The vertex of this parabola is at -5, -2. when the x-value is 4, the y-value is 2. What is the coefficient of the squared expression in the parabola's equation
Answer:
4/81 = a
Step-by-step explanation:
The vertex form of a parabola is
y = a (x-h)^2 +k where (h,k) is the is the vertex
y = a (x- -5)^2 -2
y = a (x+5)^2 -2
Substituting the point into the equation
2 = a( 4+5)^2 -2
2 = a( 9)^2 -2
2 = a (81) -2
Add 2 to each side
4 = 81 a
Divide each side by 81
4/81 = a
Answer:
a=4/81

Answer:
44,39 in
Step-by-step explanation:
To find the space diagonal (whatever it's called in English) you begin looking at the bottom of the box. We want to know the diagonal since the diagonal is one of the sides of the other triangle.
To do this we can start by using trigonometry. (SOH-CAH-TOA)
We need to use Sin t. (Since we wanna know the hypothenuse and we have the opposite.)
So...
Sin(40) = 24 in ÷ h
Then we need to actually be able to calculate this, which we will be able to do if we multiply with h on both sides.
hSin(40) = 24 in
Like that. And now we can divide both sides with Sin(40). So we calculate 24 in devided by Sin(40).
h = 24 in ÷ Sin(40) = 37,34 in
Okay so now we now the diagonal, 37,34 in. Now we can use Pythagorean theorem. (2a+2b=2c and c = square root of (2a+2b))
37,34 in^(2) + 24 in^(2) = 1970,28
And now we take the square root of 1970,28.
Which is about 44,39 in.

Enter the numerical coordinates of the vertices of quadrilateral ABCD in the table. (Point A has been done for you.) Then predict the numerical
coordinates of the vertices of quadrilateral A'B'C'D' as the figure translates four different ways: 7 units up, 1 unit down, 4 units to the right, and 3
units to the left.
9514 1404 393
Answer:
up: (-3, 5); down: (-3, -3); right: (1, -2); left: (-6, -2)
Step-by-step explanation:
As you know, the coordinates of a given point tell you the distance ...
(right, up)
So, a displacement 7 units up adds 7 to the second coordinate value:
A(-3, -2) ⇒ A'(-3, -2+7) = A'(-3, 5) . . . . 7 units up
Likewise, 1 unit down subtracts 1 unit from the second coordinate value:
A(-3, -2) ⇒ A'(-3, -3) . . . . 1 unit down
__
Similarly, left-right changes affect only the first coordinate. Displacements right are added; displacements left are subtracted.
A(-3, -2) ⇒ A'(-3+4, -2) = A'(1, -2) . . . . 4 units right
A(-3, -2) ⇒ A'(-6, -2) . . . . 3 units left

-5x-4y=2a 4x-5y=2 which of the following choices of A will results in a system of linear equations with exactly one solution
Answer:
Any of them. a ∈ RStep-by-step explanation:
-5x - 4y = 2a 4x - 5y = 2
-4y = 5x + 2a -5y = -4x + 2
y = (5x + 2a):(-4) y = (-4x + 2):(-5)
y = -⁵/₄x - ¹/₂a y = ⁴/₅x - ²/₅
m₁ = -⁵/₄, b₁ = -¹/₂a m₂=⁴/₅, b₂= -²/₅
-⁵/₄ ≠ ⁴/₅
Different slopes means that two lines have one point of intercept (no mater what the b's are). That means that the system of linear equations has exactly one solution for any value of a.
On the first visit to the veterinarians office chorus kitten weighed 550 g on the second visit the kitten had ganged 350 g on the third visit the kitten had gained 300 g what is the percent increase since the first visit in the kittens wait rounded to the nearest percent
Answer:
[tex]\%Increase = 118\%[/tex]
Step-by-step explanation:
Given
[tex]Initial\ Weight = 550g[/tex]
[tex]First\ Addition = 350g[/tex]
[tex]Second\ Addition = 300g[/tex]
Required
Determine the percentage increment
First, we have to calculate the new weight
[tex]New\ Weight = Initial\ Weight + First\ Addition + Second\ Addition[/tex]
[tex]New\ Weight = 550g + 350g + 300g[/tex]
[tex]New\ Weight = 1200[/tex]
The percentage increment is then calculated as:
[tex]\%Increase = \frac{New\ Weight - Initial\ Weight}{Initial\ Weight} * 100\%[/tex]
[tex]\%Increase = \frac{1200g - 550g}{550g} * 100\%[/tex]
[tex]\%Increase = \frac{650g}{550g} * 100\%[/tex]
[tex]\%Increase = \frac{650}{550} * 100\%[/tex]
[tex]\%Increase = 1.182* 100\%[/tex]
[tex]\%Increase = 118.2\%[/tex]
[tex]\%Increase = 118\%[/tex] -- Approximated
Hence, the percentage increment is approximately 118%
Kendra just bought a new house and needs to buy new sod for her backyard. If the dimensions of her yard are 24.6 feet by 14.8 feet, what is the area of her yard? Do not include units (ft2) in your answer.
Given:
Dimensions of Kendra's yard are 24.6 feet by 14.8 feet.
To find:
The area of her yard.
Solution:
Let as consider,
Length of yard = 24.6 ft
Width of yard = 14.8 ft
We know that,
Area of a rectangle = Length × Width
Using the above formula, we get the area of her yard.
[tex]Area=24.6\times 14.8[/tex]
[tex]Area=364.08[/tex]
Area of her yard is 364.08 ft² and without including the units ft², we get 364.08.
Therefore, the area of her yard is 364.08.

2 triangles are shown. The first triangle has side lengths x, x, 50. The second triangle has side lengths 45, 45, 75. What value of x will make the triangles similar by the SSS similarity theorem? 1.5 20 30 67.5
Answer:
30
Step-by-step explanation:
yes I can tell what it is
The value of x that will make the two triangles similar by the SSS similarity theorem is: C. 30.
What is the SSS Similarity Theorem?According to the SSS similarity theorem, if all the three corresponding sides of two triangles are proportional or have the same ratio, then both triangles are similar.
If the two triangles are similar we would have:
75/50 = 45/x
Cross multiply and find x
x = (45 × 50)/75
x = 30
Thus, the value of x would be: C. 30.

how do you isolate 1/2h -2 = -5
Answer:
Here is how to isolate the variable h.
Step-by-step explanation:
First, you have to isolate the variable which in this equation is "h." So you're going to add 2 to each side, which will give you
1/2h -2 + 2 = -5 + 2
1/2h = 3
now you've isolate the variable and you can solve for h.
(h = 6)
The i-Ready Answer:
h=14
The i-Ready Explanation:
1/2h-12= -5
+12 +12 ( Add 12 on both sides )
1/2h=7
2 x 1/2h=2 x 7 ( Multiply by 2 on both sides )
h=14

If f(x)=1/3x+7 and g(x)=-2x-5, find f(g(-7))
Please help.
Answer:
[tex]f(g(-7))=10[/tex]
Step-by-step explanation:
We have the two functions:
[tex]\displaystyle f(x)=\frac{1}{3}x+7\text{ and } g(x)=-2x-5[/tex]
And we want to find:
[tex]f(g(-7))[/tex]
So, we will first find g(-7). We know that:
[tex]g(x)=-2x-5[/tex]
Then by substitution:
[tex]g(-7)=-2(-7)-5[/tex]
Evaluate. Multiply:
[tex]g(-7)=14-5=9[/tex]
Therefore, we can rewrite our expression as:
[tex]f(g(-7))=f(9)[/tex]
Since we know that:
[tex]\displaystyle f(x)=\frac{1}{3}x+7[/tex]
By substitution:
[tex]\displaystyle f(9)=\frac{1}{3}(9)+7[/tex]
Evaluate:
[tex]f(9)=3+7=10[/tex]
Therefore:
[tex]f(g(-7))=10[/tex]
Answer:
[tex]\boxed {\boxed {\sf f(g(-7))= 10}}[/tex]
Step-by-step explanation:
We are asked to find f(g(-7)) given these 2 functions:
[tex]f(x)=\frac{1}{3}x+7[/tex][tex]g(x)= -2x-5[/tex]We must work from the inside out, so first find g(-7).
1. g(-7)
The function for g is:
[tex]g(x)= -2x-5[/tex]
Since we want to find g(-7), plug -7 in for x.
[tex]g(-7)= -2(-7)-5[/tex]
Solve according the PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction.
Multiply -2 and -7.
[tex]g(-7)=14-5[/tex]
Subtract 5 from 14.
[tex]g(-7)=9[/tex]
2. f(9)
Refer back to the original problem: f(g(-7))
Since we found that g(-7) is 9, we can substitute 9 in: f(9)
The function for f is:
[tex]f(x)= \frac{1}{3} x+7[/tex]
Plug 9 in for x.
[tex]f(9)=\frac{1}{3}(9)+7[/tex]
Solve according to PEMDAS and multiply 1/3 and 9.
[tex]f(9)=3+7[/tex]
Add 3 and 7.
[tex]f(9)=10[/tex]
f(g(-7) is equal to 10

Calculate the marked price of a sweater purchased at Rs. 1075 allowing 14% discount. ( please do proper answer )
Answer:
Rs. 1250
Step-by-step explanation:
The sweater is purchased at Rs. 1075
The discount is 14%
Let y represent the marked price of the sweater
y × 14% = 1075
y × (100-14)/100= 1075
y × 86/100= 1075
y ×0.86= 1075
0.86y= 1075
Divide both sides by the coefficient of y which is 0.86
0.86y/0.86 = 1075/0.86
y = 1250
Hence the marked price is Rs. 1250
