Given that h(x) = 5-2x, find the value(s) of x when h(x) =3
Answer:
x=1
Step-by-step explanation:
We have,
h(x) = 5-2x
h(x)=3
Now,
h(x)=5-2x=3
or,5-2x=3
or,5-3=2x
or,2/2=x
Therefore, x=1 when h(x)=3
Answer:
x = 1
Step-by-step explanation:
h(x) = 3
5 - 2x = 3
2x = 2
x = 1
Darias bought 5 school binders that cost $8.00 per
binder. If a back-to-school discount of 40% was
applied to his purchase, and then a 6% sales tax was
added, what was the total cost of the binders?
Answer:
$25.44
Step-by-step explanation:
First, find the original cost of the binders:
5(8)
= $40
Find the cost with the 40% discount:
40(0.6)
= $24
Find the cost with the 6% sales tax:
24(1.06)
= $25.44
So, the total cost of the binders was $25.44
Easton is going to invest $340 and leave it in an account for 8 years. Assuming the interest is compounded quarterly, what interest rate, to the nearest tenth of a percent, would be required in order for Easton to end up with $420?
Answer:
100.7%
Step-by-step explanation:
Since the interest is compounded quarterly, and there are 4 quarters per year, that would leave us with 32 quarters total where interest is acquired. Now, we need to find the interest rate, that would be required in order to end up with 420 dollars after 32 quarters.
We can setup a formula using our period of time and the money he invested into the bank:
[tex]340(x)^{32}=420[/tex]
We can divide 340 from both sides, and simplify the right side to 21 divided by 17:
[tex]x^{32}=\frac{21}{17}[/tex]
Taking the 32th root of 21/17 is equal to 1.00662, which is equal to 100.0662%. To the nearest tenth of a percent, this is equal to 100.7%.

What is the area of the square? Help me pls
Answer and Step-by-step explanation:
First, we need to find out the circumference of the circle.
We know that the circle has a radius of 1, and that we are finding the circumference. We'll use the circumference equation of a circle.
2[tex]\pi[/tex]r
Plug in 1 for r.
[tex]2\pi (1)[/tex] = [tex]2\pi[/tex] = circumference of circle
Now, multiply the answer (the circumference) by 4 to get the perimeter of the square.
[tex]2\pi[/tex] x 4 = [tex]8\pi[/tex] = perimeter of square
Now, divide the perimeter by 4 to get what the side of the square is.
[tex]8\pi[/tex] ÷ 4 = [tex]2\pi[/tex]
Now, multiply [tex]2\pi[/tex] by [tex]2\pi[/tex] (side times side) to get the area.
[tex]2\pi[/tex] x [tex]2\pi[/tex] = [tex]4\pi[/tex]
The answer is A. [tex]4\pi[/tex]

The area of a circle is 16π cm2. What is the circle's circumference?
Answer:
C = 8 pi cm
Step-by-step explanation:
The area of a circle is given by
A = pi r^2
16 pi = pi r^2
Divide each side by pi
16 = r^2
Taking the square root
4 = r
The circumference is
C = 2 * pi *r
C = 2* pi *(4)
C = 8 pi cm

Amy, a nature photographer, randomly sampled photographs she took within the last year. She wanted to find out how many of her photographs contained flowers. The proportion of photographs that had flowers was 0.61, with a margin of error of 0.04. Construct a confidence interval for the proportion of her photographs taken within the last year contained flowers.
The Constructed confidence interval for the proportion of her photographs taken within the last year contained flowers is
[tex]CI\ E(0.57,0.65)[/tex]
From the question we are told that:
The proportion of photographs that had flowers P= 0.61
Margin of error of M.E= 0.04
Generally, the equation for Confidence interval for proportion is mathematically given by
[tex]CI=0.61 \pm 0.04[/tex]P \pm M.E
Therefore Confidence interval is
[tex]CI=0.61 \pm 0.04[/tex]
And can also be written as
[tex]CI\ E((0.61+0.04),0.61-0.04))[/tex]
[tex]CI\ E(0.57,0.65)[/tex]
In conclusion the Confidence interval is

Find the surface area of the composite figure
Answer:
268
Step-by-step explanation:
2(2×6+2×2+2×6) + 2(4×5+4×10+10×5) - 2(2×2)
= 56+220-8
= 268 cm²
Answer:
272cm
Step-by-step explanation:
So the green block has 6 sides
the height of the prism is 4cm
the length is 10cm
and the width is 5cm
to find the top and bottom sides we must find the width and length
5x10=50cm so The bottom and top are double that so 100cm is covered so far
to find the longer sides, we times 4 by 10 = 40x2 = 80cm which covers 2 sides
and the last 2 sides of the green block are the smaller ones so 4x5 = 20 but that covers one side so we times by 2 andd that gives us both sides so 40cm
all 6 sides are covered so we can add up the numbers
top and bottom = 100cm
front back = 80cm
left and right = 40
add them all up and we get 220
now we see the purple block, this is the Same process as before
top = 2x2 = 4
bottom = 2x2 = 4
front = 6x2 = 12
back = 6x2 = 12
left = 6x2 = 12
right = 6x2 = 12
add them together and we get 56cm
the surface area of both of them Is 220+56 = 276cm
however the bottom of the purple prism is on top of the top of the green prism. Because we know the surface area of the bottom of the purple (4) and the top Surface of the green (50).
this allows us to subtract the prism above because of the bottom shapes surface so the actual answer is 272cm hope this helped

A. The left end goes down; the right end goes up.
B. The left end goes up; the right end goes down,
C. Both ends go down
D. Both ends go up.
SUBMI
Answer:
Both ends go down
Step-by-step explanation:
The end behavior of the function are Both ends go down. Therefore, Option C is true.
Given that,
The function is,
[tex]f (x) = - 2 (x - 17)^4[/tex]
Now the given function is defined at x → ∞,
f (x) = - 2 × ∞
f (x) → - ∞
As x goes to -∞
f(-∞) = -2(-∞)⁴
= -2 (∞)
= -∞
So, Both ends go to -∞, or go down
Hence, The end behavior of the function are Both ends go down.
Therefore, Option C is true.

2.) Find the measure of exterior angle X:
Answer:
x = 90
Step-by-step explanation:
Here 60 is angle B, 30 is Angle a, B is The third angle of the triangle, and x is the exterior angle measurement!
60 + 30 + b= 180
a + x = 180
60 + 30 + b= 180
90 + b = 180
b = 90
90 + x = 180

Find the equation of the linear function represented by the table below in slope-intercept form.
Answer:
y = 3x+1
Step-by-step explanation:
First find the slope
m = ( y2-y1)/(x2-x1)
= (13-4)/(4-1)
= 9/3
= 3
Slope intercept form is
y = mx+b where m is the slope and b is the y intercept
y = 3x+b
Using a point from the table
10 = 3(3)+b
10 =9+b
10-9 =b
1=b
y = 3x+1
