Question 5 of 30
What is the period of the graph of y
5cos(4x – 1) + 3?

Answers

Answer 1

Answer:

Period is [tex]\frac{\pi}{2}[/tex]

Step-by-step explanation:

For the function [tex]y=acos(bx-c)+d[/tex], the period is [tex]\frac{2\pi}{|b|}[/tex].

Therefore, the period of the function is [tex]\frac{2\pi}{|b|}=\frac{2\pi}{|4|}=\frac{2\pi}{4}=\frac{\pi}{2}[/tex].

What this means is that the function's wave cycle will repeat every [tex]\frac{\pi}{2}[/tex] units.

f(x) = x +1 g(x) = x^2 - 3
find f 3
find gf3

Answers

Given: f(x) = x + 1 and g(x) = x²−3

1. Solve for f(3)

Let f(x) = f(3).

Substitute 3 for x

f(3) = 3 + 1
= 4

Therefore f(3) = 4


Solve for gf(3)

Substitute f(3) into g(x).

f(3) = 4
gf(3) = 4² − 3
= 13

Therefore gf(3) = 13

There are 6 blue marbles, 4 green marbles, and 2 red marbles. You choose 2 marbles. What is the chance that they will be blue?

If f(x) = -x2 + 6x- 1 and g(x) = 3x2- 4x-1, find (f - g)(x).

Answers

Answer:

[tex](f-g)(x)=-4x^2+10x[/tex]

Step-by-step explanation:

We are given the two functions:

[tex]f(x)=-x^2+6x-1\text{ and } g(x)=3x^2-4x-1[/tex]

And we want to find:

[tex](f-g)(x)[/tex]

This is equivalent to:

[tex]=f(x)-g(x)[/tex]

Substitute:

[tex]=(-x^2+6x-1)-(3x^2-4x-1)[/tex]

Distribute:

[tex]=-x^2+6x-1+(-3x^2+4x+1)[/tex]

Rearrange:

[tex]=(-x^2-3x^2)+(6x+4x)+(-1+1)[/tex]

Combine like terms. Hence:

[tex](f-g)(x)=-4x^2+10x[/tex]

ANSWER: (f-g) (x)= -4x2+10x

In the following figure ABCD, find the value of x​

Answers

Answer:

80°

because its diagnol so the one in the top corner is the same as x

Answer:

x = 140°

Step-by-step explanation:

Sum of exterior angles of polygon is 360°

That is, x + 70 + 80 + 70 = 360

           x + 220 = 360

           x = 360 - 220 = 140°

The soccer team collected $800 at a car wash fundraiser. They charged $5.00 for small vehicles and $10.00 for larger vehicles. The amount collected can be modeled by the equation 5x+10y=800, where x represents the number of small vehicles and y represents the number of larger vehicles. If the number of larger vehicles washed was 50, how many small vehicles were washed in total?
55
60
130
150

Answers

Answer:

60

Step-by-step explanation:

Substitute 50 for y in the formula

5x+10y=800

5x+10*50=800

5x+500=800

5x=800-500

5x=300

x=300/5

x=60

Answer:

60

Step-by-step explanation:

5x+10y = 800

5x+10(50) = 800

5x+500 = 800

5x = 800-500

5x = 300

x = 300/5

x = 60

60 small vehicles were washed in total.

proof: 5x+10y = 800  

5(60) +10(50) =800

300 + 500 = 800

800 = 800

Answers

Answer:

39 ft^2

Step-by-step explanation:

area of small rectangle

length = 3 ft

breadth = 1 ft

area of rectangle = l*b

=3*1

=3 ft^2

area of big rectangle

length = 12 ft

breadth = 3 ft

area of rectangle = l*b

=12*3

=36 ft^2

area of the figure = area of small rectangle + area of big rectangle

=3 + 36 ft^2

=39 ft^2

39 square feet

Explanatiin:
Divide shape into 2 rectangles:

Area of upper rectangle;
1 • 3 = 3 ft2

Area of lower rectangle:
3 • 12 = 36 ft2

Add both areas of rectangles:
36 + 3 = 39 ft2
