Can someone please check my answers and help/explain #4

Mathematics
1 answer:
nasty-shy [4]3 years ago
5 0

Answer:

(0,8)

Step-by-step explanation:

To get the y-intercept put all x values equal to 0 (because we want to see where y lies on the graph when x is zero.

y=2^0+3

y=2^3

y=8

The y-intercept is (0,8)

As for the rest of the answers.....

1)A) 2\sqrt{12}-5\sqrt{3} = 4\sqrt{3}-5\sqrt{3} so the final answer is -\sqrt{3}

1B) the problem is (3-\sqrt{7})(3+\sqrt{7}) a quick formula to help you solve this type of problem is (a-b)(a+b)= a^2-b^2 so you transform the question to 3^2-\sqrt{7} ^2

to get 9-7 which is 3 therefore the final answer is 3

2) when you transform a function from y=x^2-3 to y=x^2+1 the graph moves 4 units up. So the final answer is b)4 units up

Question 3a and 3b are correct

How do you divide 3/8 by 6/7 in simplest form
Ipatiy [6.2K]

Answer:

7/16

Step-by-step explanation:

First, it is good to know that when you divide fractions, you are <em>multiplying it's reciprocal</em>.

<em>6/7's reciprocal is 7/6, since the reciprocal is \frac{1}{6/7}</em>

3/8 / 6/7 =

<u>3/8 * 7/6</u>

Now that we have that, we can just multiply the two:

3/8 * 7/6 =

21/48 =

<u>7/16</u>

Hope this helped :)

An advertisement for the state fair will be painted on one of four silos along the highway into town. The silos are in the shape
fredd [130]
<h3>Answer: Silo D</h3>

===============================================

How I got that answer:

r = radius

h = height

LA = lateral surface area of cylinder

LA = 2*pi*r*h

Let's find the lateral surface area of each silo. The smallest lateral surface area will lead to the lowest total cost.

-------------

Silo A

LA = 2*pi*r*h

LA = 2*pi*6*60

LA = 720pi

-------------

Silo B

LA = 2*pi*r*h

LA = 2*pi*8*50

LA = 800pi

-------------

Silo C

LA = 2*pi*r*h

LA = 2*pi*10*34

LA = 680pi

-------------

Silo D

LA = 2*pi*r*h

LA = 2*pi*12*20

LA = 480pi

-------------

If we ignore the "pi" terms for each of the four answers above, we see that 480 is the smallest value. Silo D has the smallest lateral surface area at 480pi square feet.

-------------

Side note: to determine the total cost, you multiply the surface area by the cost per square foot ($1.20)

For example, the total cost to paint silo D is

cost = (surface area)*(price per square foot)

cost = (480*pi)*(1.20)

cost = 1809.557

cost = 1809.56

This section is optional as your teacher isnt requiring you to find the actual costs, but rather just the silo with the least amount of area. You could go the longer route to find each surface area, compute the total cost, and then compare the total costs. You should find that silo D's cost is the lowest.
