Find the slope or the y-intercept.
Which table best represents the graph of the equation theta = 45 degrees
Answer: The first option.
Step-by-step explanation:
The function is:
θ(r) = 45°
so we have a constant function (because r does not apear in the right side of the equation), this means that for every value of r, we have that θ(r) is equal to 45 degrees.
then the correct answer is the first table, because for every value of r we have that the value of theta is the same.
Table 1 best represents the graph of the equation θ(r)= 45°.
It is given that
θ(r)= 45°, which is a constant function.
What is a constant function?For a constant function, the value of the dependent variable is the same for each value of the independent variable.
So, θ will remain constant for all values of r.
r =1, θ=45°
r =2, θ=45°
r=3, θ=45°
r=4,θ=45°
Therefore, Table 1 best represents the graph of the equation θ= 45°.

Please help with this question.
The maximum height occurs at the vertex found using t = -b/2a
Solve for t
t = -20 / 2(-5) = -20/-10 = 2 seconds.
Now replace t with 2 in the original equation to solve for the height:
h(t) = -5t^2 + 20t + 110
h(2) = -5(2)^2 + 20(2) +110
h(2) = -5(4) + 40 + 110
h(2) = -20 + 40 + 110
h(2) = 130

The table below represents a linear function f(x) and the equation represents a function g(x):
x f(x)
−1 −12
0 −6
1 0
g(x)
g(x) = 2x + 6
Part A: Write a sentence to compare the slope of the two functions and show the steps you used to determine the slope of f(x) and g(x).
Part B: Which function has a greater y-intercept? Justify your answer.
Answer:
1.the slope of the function f(x) is greater than the slope of the function g(x)
2. the y intercept in the function g(x) is the greater
Step-by-step explanation:
1. plot the graph for the function f(x)
identify points in on the line, i.e (2,6) and (1,0)
find the slope of function f(x)= change in y/change in x
m=(6-0)/2-1 = 6
equation for the function f(x)= {y-6/x-2}=6
y-6=6x-12
y=6x-6
2. the equations for functions
f(x) is given by y=6x-6
g(x) is given by y=2x+6
y intercept for f(x) =- 6
y intercept for g(x)= +6
g(x) has greater y intercept.
QUESTION A
We can use any two points from the table to determine the slope of the linear function represented by table.
We use (0,-6) and (1,0).
We use the formula,
[tex]m = \frac{y_2-y_1}{x_2-x_1} [/tex]
[tex]m = \frac{0 - - 6}{1 - 0} = 6[/tex]
For the second function
[tex]g(x) = 2x + 6[/tex]
This function is of the form;
[tex]y = mx + c[/tex]
where
[tex]m = 2[/tex]
is the slope.
The slope of f(x) is greater than the slope of g(x).
Part B
At y-intercept , x=0.
From the table, x=0 when y=-6.
Therefore f(x) has y-intercept -6.
For
[tex]g(x) = 2x + 6[/tex]
the y-intercept is 6.
Therefore g(x) has greater y-intercept.

Here is your answer. x^5-3x^4+6x^2+x-9
his recipe makes 5 pancakes.
Sanjay follows the recipe but wants to make 20 pancakes.
How much of each ingredient does he need?
Recipe: Makes 5
135 g flour
1 teaspoon (tsp) baking powder
2 tablespoons (tbsps) sugar
130 ml milk
1 egg
2 tablespoons (tbsps) oil
Answer:
540g flour
4tsp baking powder
8tbsps sugar
520mL milk
4 eggs
8tbsps oil
Step-by-step explanation:
To find out how many times he would need to make the recipe, we can divide 20 by 5:
[tex]\frac{20}{5} =4[/tex]
Now we know that Sanjay must make the recipe four times to make 20 pancakes. We need to multiply each value by 4 to get how much he needs to make 20.
[tex](4)(135)=540\\(4)(1)=4\\(4)(2)=8\\(4)(130)=520\\(4)(1)=4\\(4)(2)=8[/tex]
Sanjay can make 20 pancakes by multiplying each ingredient in the original recipe for 5 pancakes by 4. This gives 540 g flour, 4 tsp baking powder, 8 tbsps sugar, 520 ml milk, 4 eggs, and 8 tbsps oil.
To adjust the quantities of ingredients for a recipe to make a different number of servings, we multiply the amounts of each ingredient by the factor that represents how many times the original number of servings we want to make. Sanjay's goal is to make 20 pancakes instead of 5, which is 4 times the original recipe. We'll multiply each ingredient quantity by 4 to find out how much of each is needed for 20 pancakes.
Multiply the amount of flour (135 g) by 4 to get 540 g of flour.
Multiply the amount of baking powder (1 tsp) by 4 to get 4 tsp of baking powder.
Multiply the amount of sugar (2 tbsps) by 4 to get 8 tbsps of sugar.
Multiply the amount of milk (130 ml) by 4 to get 520 ml of milk.
Multiply the amount of eggs (1 egg) by 4 to get 4 eggs.
Multiply the amount of oil (2 tbsps) by 4 to get 8 tbsps of oil.

Answer:
[tex]x^{\frac{4}{5} }[/tex]
Step-by-step explanation:
Using the rule of exponents
[tex]a^{\frac{m}{n} }[/tex] = [tex]\sqrt[n]{x^{m} }[/tex]
[tex]a^{m}[/tex] × [tex]a^{n}[/tex] = [tex]a^{(m+n)}[/tex], hence
[tex]\sqrt[5]{x}[/tex] = [tex]x^{\frac{1}{5} }[/tex], thus
[tex]x^{\frac{1}{5} }[/tex] × [tex]x^{\frac{1}{5} }[/tex] × [tex]x^{\frac{1}{5} }[/tex] × [tex]x^{\frac{1}{5} }[/tex]
= [tex]x^{\frac{4}{5} }[/tex]
Answer:
[tex] x^{\frac{4}{5} }[/tex]
Step-by-step explanation:
We are given the following expression and we are to determine its most simplified form:
[tex] \sqrt [ 5 ] { x } . \sqrt [ 5 ] { x } . \sqrt [ 5 ] { x } . \sqrt [ 5 ] { x } [/tex]
We know that [tex] \sqrt [ 5 ] { x } [/tex] [tex] = x ^ { \frac { 1 } { 5 } } [/tex]
And since we have four of these like terms so the power of x will become 4, thus making it [tex] x ^4 [/tex].
When [tex] x ^ 4 [/tex] is combined with the square root 5, we get:
[tex]x^4 \times x^{\frac{1}{5}} = x^{\frac{4}{5} }[/tex]
(5-2i)+(3+4i)-(-6+2i)
Simplify
5 - 2i + 3 + 4i - (-6 + 2i)
Simplify brackets
5 - 2i + 3 + 4i + 6 - 2i
Collect like terms
(5 + 3 + 6) + (-2i + 4i - 2i)
Simplify
= 14
The equation (5-2i)+(3+4i)-(-6+2i) simplifies to 14 after adding real parts and imaginary parts separately, resulting in the complex number 14+0i which simplifies to 14.
Explanation:The student's question involves complex number addition and subtraction. To solve the equation (5-2i)+(3+4i)-(-6+2i), we combine like terms, which means separately adding the real parts and the imaginary parts of the complex numbers. The real parts are 5, 3, and 6 (because we subtract a negative, which becomes plus), which add up to 14. The imaginary parts are -2i, 4i, and -2i (again, subtraction of a negative becomes addition), which add up to 0i. Therefore, the final answer is 14+0i, which simplifies to 14.
A shirt originally cost $47.26, but it is on sale for $44.90. What is the percentage decrease of the price of the shirt?
Answer: 5%
Step-by-step explanation: In order to calculate the percentage of the discount we need to first calculate the amount of the discount.
$47.26 - $44.90 = $2.36 discount amount
In order to calculate the percentage of the discount you must divide the discount amount by the original cost.
$2.36 / $47.26 = .0499 = rounded off to a 5% discount
Answer:
The decrease is by 5%.

B) A rectangle with a length of 15 cm and a width of 9 cm. C) A rectangle with a length of 14 cm and a width of 7 cm. D) A rectangle with a length of 12 cm and a width of 8 cm.
Answer:
B
Step-by-step explanation:
10/6=5/3=15/9
Answer:
B) A rectangle with a length of 15 cm and a width of 9 cm
Step-by-step explanation:
In similar figures sides are in proportion .The given rectangle A has length and width in the ratio 10:6=5:3.
For option A ratio of sides for the rectangle = 9:6=3:2
For option B ratio of sides =15:9=5:3
For option C ratio of sides =14:7=2:1
For option D ratio of sides =12:8=3:2.
Option B that is A rectangle with a length of 15 cm and a width of 9 cm has the same ratio of sides as that of rectangle with side 10 cm and width 6cm.
Hence the two rectangles are similar.
If the area of a circle is 58 square feet, find the circumference. A. 42.5 ft. B. 4.25 ft. C. 22.35 ft. D. 26.99 ft.
Answer: OPTION D.
Step-by-step explanation:
The formula for calculate the circumference of a circle is:
[tex]C=2r\pi[/tex]
Where r is the radius.
The formula for calculate the area of a circle is:
[tex]A=r^2\pi[/tex]
Where r is the radius.
Solve for r from [tex]A=r^2\pi[/tex] to calculate it:
[tex]r=\sqrt{\frac{A}{\pi}}\\r=\sqrt{\frac{58ft^2}{\pi}}\\r=4.296ft[/tex]
Subsitute the radius into [tex]C=2r\pi[/tex]. Then:
[tex]C=(2)(4.296ft)\pi=26.99ft[/tex]
Answer:
D. 26.99 ft
Step-by-step explanation:
The formula for area of a circle is
A = πr², where r is the radius. We are given A = 58, so plug that in to find r...
58 = πr² solve for r...
58/π = r² (divide both sides by π)
√(58/π) = r (take the square root of both sides)
now simplify...
(√58)/(√π) = r
[(√58)(√π)]/[(√π)(√π)] = r
[√(58π)]/π = r
The formula for circumference is C = 2πr, where r is the radius....so we have
C = 2π([√(58π)]/π) now simplify...
C = 2√(58π) (the 2 pi's cancel out)
C = 26.9972124 (crunch in your calculator)

How would the graph of the function y=x2-8 be affected if the function were changed to y=x2-3
A) the graph would shift 3 units down
B) the graph would shift 5 units to the left
C) the graph would shift 5 units down
D)the graph would shift 5 units up
Answer:
D) The graph would shift 5 units up.Step-by-step explanation:
f(x) + n - shift the graph n units up
f(x) - n - shift the graph n units down
f(x - n) - shift the graph n units to the right
f(x + n) - shift the graph n units to the left
------------------------------------------------------------------
We have f(x) = x² - 8
f(x) = x² - 8 add 5 to both sides
f(x) + 5 = x² - 3
Therefore your answer is D)
The graph of the function y=x^2-8 would shift 5 units up if changed to y=x^2-3, due to the increase in the constant term.
When comparing the functions y=x^2-8 and y=x^2-3, a change in the constant term represents a vertical shift of the graph. The constant term in the function y=x^2-8 is -8, and in the function y=x^2-3 it is -3. Since -3 is greater than -8 by 5, the graph will be shifted up by 5 units. Therefore, the correct answer to how the graph of the function would be affected is that it would shift 5 units up.
