Answer:
Equation : y = x2 - 20
Intercepts
when y is zero (0), x is 10
when x is zero (0), y is -20
Therefore, shift the graph, y=2x down to the negative y-axis 20 units
ALTERNATIVELY: Shift the graph to the right of positive x-axis 10 units.
The sales tax in your city is
4.4% and an item costs
$3 before tax.
How much tax would you pay on that item?
Round to the nearest hundredth or cent.
Answer:
$0.13
Step-by-step explanation:
To find how much tax you would pay, find 4.4% of 3:
3(0.044)
= 0.132
Round to the nearest hundredth:
0.132
= 0.13
So, you would pay $0.13 in tax
It is worked out that if 4 ladles full of soup are given to each person,
160 people can be fed.
The customers have complained in the past that the portions are too small.
The cook decides to give 5 ladles full of soup to each person.
How many people can now be fed soup
Answer:
128 people
Step-by-step explanation:
160 people multiplied by 4 ladles per person equal 640 ladles in total
640 ladles divided by 5 ladles each equals 128 people

Karen will divide her garden into equal parts. She will plant corn in 12 20 of the garden. What is the fewest number of parts she can divide her garden into?
Given that,
Karen will divide her garden into equal parts. She will plant corn in 12/20 of the garden.
To find,
The fewest number of parts she can divide her garden into.
Solution,
It is mentioned that she will plant corn in 12/20 of the garden.
If we divide both numerator and denominator by 4, it will become:
[tex]\dfrac{12/4}{20/4}=\dfrac{3}{5}[/tex]
It means the fewest number she can divide her garden into is 4. 3/5 part is planted with corn and rest 2/5 is not planted with corn plant.

What is this equation called and how do I do it?
Answer:
DE ≈ 40
Step-by-step explanation:
Using the Sine rule in Δ DEF
∠ D = 180° - (58 + 87)° ← sum of angles in a triangle
∠ D = 180° - 145° = 35° , then
[tex]\frac{DE}{sin87}[/tex] = [tex]\frac{EF}{sin35}[/tex] = [tex]\frac{23}{sin35}[/tex] ( cross- multiply )
DE × sin35° = 23 × sin87° ( divide both sides by sin35° )
DE = [tex]\frac{23sin87}{sin35}[/tex] ≈ 40 units ( to the nearest whole number )

The expression ( x 22)( x 7)3 is equivalent to xp . What is the value of p ?
Answer:
p = 43
Step-by-step explanation:
I assume you mean an expression with exponents.
In the future, for a to the n power use a^n.
Recall the following two rules of exponents:
[tex] x^a \times x^b = x^{a + b} [/tex]
[tex] (x^a)^b = x^{ab} [/tex]
Now we can answer your question.
[tex] (x^{22})(x^7)^3 = [/tex]
[tex]= (x^{22})(x^{21})[/tex]
[tex] = x^{43} [/tex]
Since
[tex] x^{43} = x^p [/tex]
then
p = 43
The diagram shows a 9cm x 7cm rectangle-based pyramid. all the diagonal sides - TA, TB, TC, AND TD- are length 12cm. M is the midpoint of the rectangular base.
Work out angle TAC, to 1 decimal place.
Answer:
∠TAC is approximately equal to 61.6°
Step-by-step explanation:
The given parameters for the pyramid are;
The dimension for the rectangular base are; Length = 9 cm, width = 7 cm
The length of the diagonal sides, TA, TB, TC, and TD = 12 cm each
The midpoint of the rectangular base = Point M
The diagonal AC = AM + MC
AM = MC as given M is the midpoint of the rectangular base
∴ AC = AM + MC = 2·AM
By Pythagoras' theorem, AC = √(9² + 7²) = √130
AC = √130 cm
∴ AM = AC/2 = (√130)/2 cm
Alternatively, AM = √((9/2 cm)² + (7/2 cm)²) = √(32.5) cm
∠TAC = ∠TAM
By trigonometric ratios, we have;
[tex]cos (\theta) = \dfrac{Length \ of \ adjacent \ side \ to \ angle }{Length \ of \ hypotenuse\ side \ to \ angle}[/tex]
[tex]\therefore cos (\angle TAM) = cos (\angle TAC) = \dfrac{\left (\dfrac{\sqrt{130} }{2} \right )}{12} = \dfrac{\sqrt{130} }{2 \times 12} = \dfrac{\sqrt{130} }{24}[/tex]
[tex]\angle TAC = arccos \left ( \dfrac{\sqrt{130} }{24} \right ) \approx 61.6 ^{\circ} \ to 1 \ decimal \ place[/tex]
The measure of angle TAC is 61.6 degrees
The given parameters are:
[tex]\mathbf{AB = 7}[/tex]
[tex]\mathbf{BC = 9}[/tex]
Start by calculating length AC, using the following Pythagoras theorem.
[tex]\mathbf{AC = \sqrt{AB^2 + BC^2}}[/tex]
So, we have:
[tex]\mathbf{AC = \sqrt{7^2 + 9^2}}[/tex]
[tex]\mathbf{AC = \sqrt{49 + 81}}[/tex]
[tex]\mathbf{AC = \sqrt{130}}[/tex]
[tex]\mathbf{AC = 11.40}[/tex]
Next, we calculate side length AM
[tex]\mathbf{AM = \frac{AC}{2}}[/tex]
So, we have:
[tex]\mathbf{AM = \frac{11.40}{2}}[/tex]
[tex]\mathbf{AM = 5.70}[/tex]
The measure of angle TAC is calculated using the following cosine ratio
[tex]\mathbf{cos(A)= \frac{AM}{TA}}[/tex]
So, we have:
[tex]\mathbf{cos(A)= \frac{5.70}{12}}[/tex]
[tex]\mathbf{cos(A)= 0.475}[/tex]
Take arc cos of both sides
[tex]\mathbf{A= 61.6}[/tex]
Hence, the measure of angle TAC is 61.6 degrees

What is the first step in solving this problem 4/5 + 1/2
The first step is to make the fractions have a common denominator. It can be achieved by finding the LCM (Lowest common multiple) of the fractions denominators
From the question,
The given expression is 4/5 + 1/2
This can be written properly as
[tex]\frac{4}{5}+\frac{1}{2}[/tex]
In solving the problem, the first step is to make the fractions have a common denominator. This can be achieved by finding the LCM (Lowest common multiple) of their denominators (that is, 5 and 2)
The LCM of 5 and 2 is 10
If we were to solve the equation, we will get
[tex]\frac{4}{5}+\frac{1}{2}[/tex] = [tex]\frac{2(4) + 5(1)}{10}[/tex]
Hence, the first step is to make the fractions have a common denominator. It can be achieved by finding the LCM (Lowest common multiple) of the fractions denominators.
