Step-by-step explanation:
The given parameters are
To translate the square OABC by the vector [tex]\dbinom{1}{3}[/tex], we have;
The coordinates of the point O is (0, 0)
The coordinates of the point A is (3, 0)
The coordinates of the point B is (3, 3)
The coordinates of the point C is (0. 3)
The translation is by moving 1 step right and three steps up to give;
O' is (0+1, 0+3) which is (1, 3)
A' is (3+1, 0+3) which is (4, 3)
B' is (3+1, 3+3) which gives (4, 6)
C' is (0+1, 3+3) which gives (1, 6)
As all the points change, there are no invariant points and the number of invariant points is zero.

Sophia‘s favorite homemade cookie recipe requires one cup of chocolate chips for 10 servings if the number of cups required for multiple batches is proportional to the number of servings being made how many cups of chocolate chips will she need to make enough cookies for 30 servings
Answer:
3 cups
Step-by-step explanation:
We can use a proportion to find how many cups of chocolate chips she needs for 30 servings. Assuming c = cups of chocolate chips and b = batches
[tex]\frac{c}{b}[/tex]
[tex]\frac{1}{10} = \frac{c}{30}[/tex]
We can now multiply the diagonal values that don't include the missing variable (30 and 1) and then divide it by the value that is diagonal to the variable (10)
[tex]30 \cdot 1 = 30\\30 \div 10 = 3[/tex]
Therefore, she needs 3 cups of chocolate chips to make 30 servings.
Answer:
3 cups
Step-by-step explanation:
We can use ratios to solve
1 cup x cups
---------------- = ----------------
10 servings 30 servings
Using cross products
1*30 = 10x
Divide by 10
30/10 = x
3 =x

continuation of previous question :)
Answer:
Below
Step-by-step explanation:
First let's determine the slope if thus function
Let m be the slope of this function
m = [0-(-4)]/ 2-0 = 4/2 =2
So our equation is:
y = 3x +b
b is the y-intercept wich is given by the image of 0
Here it's -4
So the equation is:
y = 2x-4 wich is also y = x-2 after simplifying
●●●●●●●●●●●●●●●●●●●●●●●●
A line that is parallel to this one will have the same slope.
Examples:
● y= 2x+3
● y = 2x-7
■■■■■■■■■■■■■■■■■■■■■■■■■■
A line that is perpendicular to this one and has a slope m' satisfy this condition:
m*m'= -1
m'= -1/m
m' = -1/2
So this line should have a slope that is equal to -1/2
Answers from the choices:
y = -1/2 x +1/2
y+1= -1/2 (x-3)
The formula for the area of a triangle is A = 1/2bh, where b represents the length of the base and h represents the height. Part A; solve the formula for b.
Answer:
b = [tex]\frac{2A}{h}[/tex]
Step-by-step explanation:
Given
A = [tex]\frac{1}{2}[/tex] bh
Multiply both sides by 2 to clear the fraction
2A = bh ( divide both sides by h )
[tex]\frac{2A}{h}[/tex] = b
Parallel lines p and q are cut by transversal r. On line p where it intersects with line r, 4 angles are created. Labeled clockwise, from the uppercase left, the angles are: 1, 2, 4, 3. On line q where it intersects with line r, 4 angles are created. Labeled clockwise, from the uppercase left, the angles are: 5, 6, 8, 7. m∠3 is (3x + 4)° and m∠5 is (2x + 11)°. Angles 3 and 5 are . The equation can be used to solve for x. m∠5 = °
Answer:
m∠5 = 77
Step-by-step explanation:
∠3 & ∠ 5 are the co interior angles in the same side of the transversal
∠3 + ∠5 = 180 {sum of co interior angles is 180}
3x + 4 + 2x +11 = 180 {Add like terms}
5x + 15 = 180
Subtract 15 from both sides
5x + 15 - 15 = 180 -15
5x = 165
Divide both side by 5
5x/5 = 165/5
x = 33°
m∠5 = 2x + 11 = 2*33 + 11
= 66 + 11
= 77
Answer:
m∠3 is (3x + 4)° and m∠5 is (2x + 11)°.
Angles 3 and 5 are "same side interior angles"
The equation "(3x + 4) + (2x + 11) = 180" can be used to solve for x.
m∠5 = "77°"
Step-by-step explanation:
4^3/4 x 2^x = 16^2/5
work out the exact value of x
Answer:
x = 1/10Step-by-step explanation:
[tex] {4}^{ \frac{3}{4} } \times {2}^{x} = {16}^{ \frac{2}{5} } [/tex]
In order to solve the equation express each of the terms in the same base .
in this case we express each of the terms in base 2
That's
[tex] {4}^{ \frac{3}{4} } = {2}^{2 \times \frac{3}{4} } = {2}^{ \frac{3}{2} } [/tex]
And
[tex] {16}^{ \frac{2}{5} } = {2}^{4 \times \frac{2}{5} } = {2}^{ \frac{8}{5} } [/tex]
So we have
[tex] {2}^{ \frac{3}{2} } \times {2}^{x} = {2}^{ \frac{8}{5} } [/tex]
Since the left side are in the same base and are multiplying, we add the exponents
[tex] {2}^{ \frac{3}{2} + x } = {2}^{ \frac{8}{5} } [/tex]
Since they have the same base we can equate them
That's
[tex] \frac{3}{2} + x = \frac{8}{5} [/tex]
[tex]x = \frac{8}{5} - \frac{3}{2} [/tex]
[tex]x = \frac{1}{10} [/tex]

Answer:
m∠C = 90°
Step-by-step explanation:
Triangle BDC is a right triangle with the measure of angle D = 90°
By applying Cosine rule in the given triangle,
Since, Cosine of any angle in a right triangle is a ratio of Its adjacent side and Hypotenuse (Opposite side of the right angle)
CosC = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]
CosC = [tex]\frac{\text{DC}}{\text{BC}}[/tex]
CosC = [tex]\frac{7}{8}[/tex]
[tex]C=\text{Cos}^{-1}(\frac{7}{8})[/tex]
C = 28.955
C = 29°
Therefore, m∠C = 29° will be the answer.

The length of a rectangular field is twice its breadth. If the area of the rectangular field is 98 sq. M., then what is the perimeter of the field? Also find the approximate length of the diagonal of the field.
Answer:
Perimeter = 42mlength of the diagonal ≈ 16mStep-by-step explanation:
The Area of the rectangular field is expressed as A = LB and its perimeter
P = 2(L+B)
L is the length of the rectangular field
B is the Breadth of the rectangular field
If the length of a rectangular field is twice its breadth i.e L = 2B and the area is 98m² then;
98 = LB
98 = 2B*B
98 = 2B²
B² = 98/2
B² = 49
B = √49
B = 7m
if B = 7m
L = 98/B
L = 98/7 = 14m
The perimeter of the field P = 2(L+B)
P = 2(14+7)
P = 2*21
P = 42m
The perimeter of the field is 42m.
The length of the diagonal of the field can be expressed using Pythagoras theorem.
d = √L²+B²
d = √14²+7²
d = √196+49
d = √245
d = 15.7m ≈ 16m
Hence, the approximate length of the diagonal of the field is 16m
The speed(S) of a car varies partly directly as its mass(M) and partly directly as the quantity (Q) of fuel in it. When the speed is 80km/hr, the mass is 220kg and the quantity of fuel is 30litres, when the speed is 60km/hr, the mass is 300kg and the quantity of fuel is 40 litres. Find the volume of fuel if the speed is 100km/hr and the mass 250kg. DO NOT WRITE TRASH I WILL REPORT YOU
Answer:
Quantity of fuel is 24 L, based on the model S=2400/Q when S=100
Step-by-step explanation:
If the output power of the car remains constant, the speed would reduce as the masses increase, which is the shown in the observed data.
Hence S does NOT vary directly with the mass and quantity, but varies INVERSELY with the mass and fuel (which has a mass).
Many models are possible to fit the results. Product models with a single constant k
S(m,q) = kmq and S(m,q) = k/mq
do not fit both observation, hence rejected.
A possible model with two constants is shown below
S(m,q) = k1/m + k2/q..................(1)
1. m=220, q=30 => 80 = k1/220 + k2/30 ..........(2)
2. m=300, q=40 => 60 = k1/300 + k2/40 ..........(3)
Solve system (2) and (3) gives k1=0, k2 = 2400.
So it appears that the speed is independent of the mass (m) [unlikely], but inversely proportional to the quantity (q) of fuel, giving
S(q) = 2400/q
When speed = 100 km/h, and mass = 250 kg, substitute
100 = 2400/q => q=2400/100 = 24
What is the solution to the following equation?
5(2x - 6) + 20 = 10
09
05
03
O2
Answer:
x = 2
Step-by-step explanation:
5(2x- 6) + 20 = 10
10x - 30 = -10
10x = 20
x = 2
Answer:
O2
Step-by-step explanation:
5(2x-6)+20=10
Use distirbutive property:
10x-30 because, 5×2 = 10, and 5×6=30
Now we have
10x-30+20=10
Now combine the like terms
10x-10=10
Send the 10 to the other side(it turns into positive 10 because it was negative 10 on the other side)
10x = 10+10
10x=20
Divide 10 by both sides
x/10 = 20/10
x=2

Justin weighed 8 lb 12 oz when he was born. At his two-week check-up, he had gained 8 ounces. What was his weight in pounds and ounces?
Answer:
9 lb 4 oz
Step-by-step explanation:
Justin weighed 8 lb 12 oz at birth. He gained 8 ounces by his two-week checkup. So,
8 lb 12 oz + 8 oz = 8 lb 20 oz
But, 16 oz equals one pound. So,
20 oz = 1 lb with 4 oz remaining
Now add them together.
8 lb + 1 lb 4 oz = 9 lb 4 oz
Justin's weight is 9 lb 4 oz.
Hope that helps.
Help please you need to find the rise in the blue triangle. Thank you!!
Answer:
12.65
Step-by-step explanation:
In the case of the blue triangle, to calculate the rise, which would be the increase, therefore it would be the hypotenuse formed by the arrow.
We have to Pythagoras is:
h ^ 2 = a ^ 2 + b ^ 2
In this case:
a (x-axis) = 4
b (y-axis) = 12
replacing:
h ^ 2 = 4 ^ 2 + 12 ^ 2
h ^ 2 = 160
h = 12.65
Which means that the rise in the blue triangle is 12.65 units
NEED HELP ON THIS A S A P
Answer:
150
Step-by-step explanation:
Given the function [tex]h:x=px-\frac{5}{2}[/tex] and the inverse function [tex]h^{-1} :x=q+2x[/tex], where p and q are constants, find a) the value of p and q c)[tex]h^{-1} h(-3)[/tex]
Answer:
[tex]p = \frac{1}{2}[/tex]
[tex]q = 5[/tex]
[tex]h^{-1}(h(3)) = 3[/tex]
Step-by-step explanation:
Given
[tex]h(x) = px - \frac{5}{2}[/tex]
[tex]h^{-1}(x) = q + 2x[/tex]
Solving for p and q
Replace h(x) with y in [tex]h(x) = px - \frac{5}{2}[/tex]
[tex]y = px - \frac{5}{2}[/tex]
Swap the position of y and d
[tex]x = py - \frac{5}{2}[/tex]
Make y the subject of formula
[tex]py = x + \frac{5}{2}[/tex]
Divide through by p
[tex]y = \frac{x}{p} + \frac{5}{2p}[/tex]
Now, we've solved for the inverse of h(x);
Replace y with [tex]h^{-1}(x)[/tex]
[tex]h^{-1}(x) = \frac{x}{p} + \frac{5}{2p}[/tex]
Compare this with [tex]h^{-1}(x) = q + 2x[/tex]
We have that
[tex]\frac{x}{p} + \frac{5}{2p} = q + 2x[/tex]
By direct comparison
[tex]\frac{x}{p} = 2x[/tex] --- Equation 1
[tex]\frac{5}{2p} = q[/tex] --- Equation 2
Solving equation 1
[tex]\frac{x}{p} = 2x[/tex]
Divide both sides by x
[tex]\frac{1}{p} = 2[/tex]
Take inverse of both sides
[tex]p = \frac{1}{2}[/tex]
Substitute [tex]p = \frac{1}{2}[/tex] in equation 2
[tex]\frac{5}{2 * \frac{1}{2}} = q[/tex]
[tex]\frac{5}{1} = q[/tex]
[tex]5 = q[/tex]
[tex]q = 5[/tex]
Hence, the values of p and q are:[tex]p = \frac{1}{2}[/tex]; [tex]q = 5[/tex]
Solving for [tex]h^{-1}(h(3))[/tex]
First, we'll solve for h(3) using [tex]h(x) = px - \frac{5}{2}[/tex]
Substitute [tex]p = \frac{1}{2}[/tex]; and [tex]x = 3[/tex]
[tex]h(3) = \frac{1}{2} * 3 - \frac{5}{2}[/tex]
[tex]h(3) = \frac{3}{2} - \frac{5}{2}[/tex]
[tex]h(3) = \frac{3 - 5}{2}[/tex]
[tex]h(3) = \frac{-2}{2}[/tex]
[tex]h(3) = -1[/tex]
So; [tex]h^{-1}(h(3))[/tex] becomes
[tex]h^{-1}(-1)[/tex]
Solving for [tex]h^{-1}(-1)[/tex] using [tex]h^{-1}(x) = q + 2x[/tex]
Substitute [tex]q = 5[/tex] and [tex]x = -1[/tex]
[tex]h^{-1}(x) = q + 2x[/tex] becomes
[tex]h^{-1}(-1) = 5 + 2 * -1[/tex]
[tex]h^{-1}(-1) = 5 - 2[/tex]
[tex]h^{-1}(-1) = 3[/tex]
Hence;
[tex]h^{-1}(h(3)) = 3[/tex]
Lily is using dark power crystals to raise an army of zombies. Each crystal can raise 999 zombies. How many crystals does Lily need to raise 6{,}1746,1746, comma, 174 zombies?
Answer:
X= 618079825.9
Y= 6.18 crystals
Step-by-step explanation:
It takes Lily a crystal to raise 999 zombies.
It will take her x crystals to Raise 617461746174 zombies
Mathematically
One crystal= 999 zombies
X = 617461746174
X=( 617461746174*1)/999
X= 617461746174/999
X= 618079825.9
Again
It took one crystal to raise 999 zombies
It will take y crystal to raise 6174 zombies
Mathematically
One = 999
Y =( 6174*1)/999
Y= 6.18 crystals

Answer:
E. y = 2/3x
Step-by-step explanation:
You need to make an equation in slope-intercept form.
First, you need to find the slope. You can do this by taking two points and dividing the difference of the y's by the difference of the x's. I will use the first two points, but you can pick whichever points you want and still get the right answer. Also, the values in the left column will be x's, and the values in the right column will be y's.
8 - 2 = 6
12 - 3 = 9
6/9 = 2/3
The slope is 2/3. The only equation with this value is E.
Let $S = 2010 + 2011 + \cdots + 4018$. Compute the residue of $S$, modulo 2009.
Notice that
2010 ≡ 1 mod 2009
2011 ≡ 2 mod 2009
2012 ≡ 3 mod 2009
...
4017 ≡ 2008 mod 2009
4018 ≡ 0 mod 2009
So really, S is just the sum of the first 2008 positive integers:
[tex]S=\displaystyle\sum_{n=1}^{2008}n=\frac{2008\cdot2009}2[/tex]
where we invoke the formula
[tex]\displaystyle\sum_{i=1}^ni=\frac{n(n+1)}2[/tex]
and so S ≡ 0 mod 2009.

A car travels 32 km due north and
then 46 km in a direction 40° west of
north. Find the magnitude of the
car's resultant vector.
Answer:
73.2km
Step-by-step explanation:
first you have to decompose 46 km into y and x components.
x=sin40°*46km
x=0.64*46km
x=29.44km
y=cos40°*46km
y=0.76*46km
y=34.96
now you add the y components together
32+34.96=66.98
finally use Pythagorean thereom to find the resultant vector.
a*a+ b*b=c*c
66.98*66.98+29.44*29.44=c*c
c*c= 4486.3+866.7
c=√5353
c=73.2 km this is the approximate value
