Answer:
Step-by-step explanation:
Given
f(x) = 5x - 1
g(x) = x² - 4
Now
(fog)(0) = f (0² - 4)
= f( - 4 )
= 5 (-4) - 1
= -20 - 1
= - 21
hope it helps :)
Value of composite function fog(0) is -21
What is function?A function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the co-domain of the function.
Given,
f(x) = 5x - 1
g(x) = x² - 4
fog(x)
= f(g(x))
= 5(x² - 4) - 1
x = 0
fog(0) = 5(0² - 4) - 1
fog(0) = -20 - 1
fog(0) = -21
Hence, -21 value of composite function fog(0)

Answer:
240.34Step-by-step explanation:
ΔA = 90° - 31°
= 59°
sin A = perpendicular ÷ base
sin 59° = 400 ft ÷ y
1.6643 = 400 ft ÷ y
y = 400 ÷ 1.6643
y = 240.34 ft

Answer:
10°, 80°
Step-by-step explanation:
Setup
Let x and y represent the measures of the two acute angles in the right triangle.
From your knowledge of right triangles, you know the two acute angles are complementary:
x + y = 90
The problem statement gives you another relation:
x = 2(y + 30) . . . . twice the sum ...
__
Solution
The second equation gives you an expression for x that can be substituted into the first equation.
(2(y +30)) + y = 90
3y +60 = 90 . . . . . . . . collect terms
3y = 30 . . . . . . . . . subtract 60
y = 10 . . . . . . . . divide by 3
x = 2(y +30) = 2(40) = 80
The two angles are 10° and 80°.
Question 1 of 10 Enter the slope-intercept equation of the line that has slope 4 and y-intercept (0, 11).
Answer:
y=4x+11
Step-by-step explanation:
The formula for slope intercept is y=mx+b
m= slope
b= y intercept
hence, y=4x+11
Write the equation of the line that includes the point (3,3) and has a slope of 2.
Answer:
y = 2x - 3
Step-by-step explanation:
We are given the slope, m = 2
Our standard formula of a line is y = mx + b, so we can substitute for the x and y values of the point (3, 3). If you did not know, the x-value and the y-value are both 3 because the point (3, 3) = (x, y).
So, our equation looks like this:
3 = (2)(3) + b
We can solve for b:
3 = 6 + b
b = -3
And now we have our equation of a line:
y = 2x - 3

Answer:

Step-by-step explanation:
The sum of the measures of the angles of a quadrilateral is 360°
360 - 40 - 80 - 110 = 130
130 is the measure of the quad that is adjacent to the angle of x° and is supplementary to that angle also.

Pedro is getting balloons for his grandmother's birthday party. He wants each balloon string to be 12 feet long. At the party store, string is sold by the yard. If Pedro wants to get 52 balloons, how many yards of string will he need? 1 foot = 1 3 yard
Answer:
Total length of string required in yards [tex]8112[/tex] yards
Step-by-step explanation:
The length of the string attached with each balloon is equal to [tex]12[/tex] feet
In the party total number of balloon used is equal to [tex]52[/tex] balloons
The total length of the string required
Length of string used in one balloon * total number of balloons
[tex]= 12 * 52 = 624[/tex] feet
1 feet is equal to 13 yards
Total length of string required in yards [tex]13 * 624 = 8112[/tex] yards

32°F or lower. Recess at her school always starts on the half hour or hour. Which statement is true about recess at
Polina's school?
Only students who have recess at 11:00 a.m. or later may go outside.
Only students who have recess at 11:30 a.m. or later may go outside.
Only students who have recess at 12:00 p.m. or later may go outside,
Only students who have recess at 12:30 p.m. or later may go outside.
Save and Fxit
Answer:
12pm or later
Step-by-step explanation:
if she is starting at midnight, 12am, then it would take 12 hours to make the temperature above 32.
write an inequality that describes the situation. the starting temperature is 18, so we add the 18 to the rest of the inequality because that is what we have already so we really don't have to do anything with it. 1.2 is for the amount that the temperature rises at and x is for how many hours it will take. this all needs to be greater than 32 degrees.
18+1.2x>32
-18 -18
1.2x=14
/1.2 /1.2
x=11.67
this decimal place means that it would take over 11 and a half hours for the temperature to be above 32. therefore, anytime after 12pm would be ok for the kids to go outside.

In September, Louise planted a tree. Every month, the tree Louise planted grew 2 inches. What would the constant of proportionality of the line be?
Answer:
1/2
Step-by-step explanation:
Tree grow 2 inches per month
Let :
Month = m ; height increase, h
m α h
m = kh
k = proportionality constant
Where ; m = 1 ; h = 2
1 = 2k
1/2 = 2k/ 2
k = 1/2
Answer:1/2
Step-by-step explanation:
Tree grow 2 inches per month
Let :
Month = m ; height increase, h
m α h
m = kh
k = proportionality constant
Where ; m = 1 ; h = 2
1 = 2k
1/2 = 2k/ 2
k = 1/2
Greg chose C as the answer. How might he have gotten that answer?
Given:
The equation is
[tex]-0.4x+0.05y-1.25=0[/tex]
Where, y is the total cost and x is the number of months.
To find:
The y-intercept of the line represented by this equation.
Solution:
We have,
[tex]-0.4x+0.05y-1.25=0[/tex]
Isolate y variable.
[tex]0.05y=0.4x+1.25[/tex]
Divide both sides by 0.05.
[tex]y=\dfrac{0.4x+1.25}{0.05}[/tex]
[tex]y=\dfrac{0.4x}{0.05}+\dfrac{1.25}{0.05}[/tex]
[tex]y=8x+25[/tex]
Putting x=0, we get
[tex]y=8(0)+25[/tex]
[tex]y=0+25[/tex]
[tex]y=25[/tex]
Therefore, the y-intercept of the given equation is 25 and the correct option is D.
