f(x) = -4x2 + 10
Find f(-2)
Answer:
f(-2) = -6
Step-by-step explanation:
In the expression, to get f(-2);
we simply substitute the value of x with -2
We have this as;
f(-2) = -4(-2)^2 + 10
f(-2) = -4(4) + 10
f(-2) = -16 + 10
f(-2) = -6
The scale drawing of a porch is 8 inches wide by 12 inches long. If the actual porch is 12 feet wide, find the length of the porch. (Draw and label polygons then solve.)
Answer: The length of porch is 18 feet.
Step-by-step explanation:
Given: The scale drawing of a porch is 8 inches wide by 12 inches long.
The actual porch is 12 feet wide.
Actual porch and the drawing are similar, then
[tex]\dfrac{\text{Actual length}}{\text{Actual width}}=\dfrac{\text{ length in drawing}}{\text{Width in drawing}}[/tex]
[tex]\Rightarrow\ \dfrac{\text{Actual length}}{12}=\dfrac{12}{8}\\\\\Rightarrow\ \text{Actual length}= \dfrac{12}{8}\times12\\\\\Rightarrow\ \text{Actual length}= 18[/tex]
Hence, the length of porch is 18 feet.
Given that the corresponding sides of similar shapes are proportional, the length of the porch would be calculated as: 18 inches.
What are Similar Shapes?Shapes that are similar have corresponding sides that are proportional to each other.
Thus:
Length of scale drawing = 12 inchesActual length of porch = xWidth of scale drawing = 8 inchesActual width of porch = 12 ftTherefore:
x/12 = 12/8
Cross multiply
8x = (12)(12)
x = 18 inches.
Therefore, given that the corresponding sides of similar shapes are proportional, the length of the porch would be calculated as: 18 inches.

Identify the domain and range of each of the graphs below.
Domain:
Range:
Answer:
Domain → (-∞, ∞)
Range → (-∞, ∞)
Step-by-step explanation:
Domain of a function is defined by the x-values or input values of the graph.
Similarly, Range of the function is defined by the y-values or output values from the graph.
From the picture attached,
x - values for the line shown in the graph vary from negative infinity to positive infinity.
Therefore, Domain of the function will be → (-∞, ∞)
And for every x-value there is a y-value, so Range of the function will be same as domain (varying from negative infinity to positive infinity) → (-∞, ∞)

The equation perpendicular to the given equation is y=-3x-9. Therefore, option B is the correct answer.
Given that, the equation of the line is y+2 = 1/3 (x-5) and the coordinate point is (-4, 3).
Here, the slope is 1/3
The slope of a line perpendicular to given line is m1=-1/m2
So, the slope is m=-3
Substitute m=-3 and (x, y)=(-4, 3) in y=mx+c, we get
3=-3×(-4)+c
3=12+c
c=-9
So, the equation is y=-3x-9
Therefore, option B is the correct answer.

Step-by-step explanation:
A weather station reported 90% of the days in a 30-day period had measurable snowfall. How many of these days received measurable snowfall?
Answer:
27 days.
Step-by-step explanation:
Find 1% out of the 30-day period.
100% = 30 days
1% = 30 ÷ 100 = 0.30
Now find the percentage reported that had measurable snowfall which is 90%.
90% = 0.30 x 90 = 27
Out of the 30-day period, only 27 days received measurable snow.
Fourteen of the people signed up for the ski classes are beginners. If 56% of those signed up are beginners, how many people signed up for classes?
Answer:
25
Step-by-step explanation:
An unknown number of people signed up for the class. Let the total number of people who signed up be x.
56% of the people who signed up are beginners. 14 people are beginners.
That means that
56% of the people who signed up is 14 people.
56% of x = 14
56% * x = 14
0.56x = 14
Divide both sides by 0.56.
0.56x/0.56 = 14/0.56
x = 25
Answer: 25
