Let's plug in 2 for t and solve and h:
h(t) = -16t^2 + 541
h(2) = -16(2^2) + 541
h(2) = -16*4 + 541
h(2) = -64 + 541
h(2) = 477 feet
Answer is b) 477 feet

After completing the fraction division 5 divided by five-thirds, Miko used the multiplication shown to check her work. 3 times f
Dmitry [639]

Step-by-step explanation:

5 divided by five-thirds can be written in the fractional form is as follows :

\dfrac{5}{\dfrac{5}{3}}

It can be also written as :

\dfrac{5}{\dfrac{5}{3}}=5\times \dfrac{3}{5}\\\\=3

He has done calculations as follows :

3 x 5/3=3/1 x 5/3 = 15/3 or 5

Miko was wrong in the first step where he multiplied 3 by (5/3). It should be 5 multiplied by (3/5). He has done multiplication incorrectly.

WILL GIVE BRAINIEST 2.find the values of x and y a. x=15 y=12 b.x=14 y=11 c.x=14 y=12 d.x=15 y=11
liubo4ka [24]

3x - 7 = 2x + 7

3x - 2x = 7 + 7

x = 14


2x + 7 + 12y + 1 = 180

2(14) + 7 +  12y + 1 = 180

12y + 36 = 180

12y = 144

y = 12

Answer

x = 14 and y = 12

Math homework help please thanks!
trapecia [35]

Answer:

x = 5

Step-by-step explanation:

I already answer this on another question you actually made, but here it is again:

To do this, you need to use the Thales theorem.

You can actually apply this theorem and choose two sides of the figure to do it.In this case, I will choose segment LM and MN and look for a ratio with DE and EF like this:

LM/MN = DE/EF

This theorem states that you can stablish a ratio between two segments assuming that you have at least two paralels lines, like DL || EM || FN

Therefore, it's time to replace the values of those segments and solve for X:

LM/MN = DE/EF

14/16 = 6x -9 / 4x + 4

7/8 = 6x - 9 / 4x + 4

7(4x+4) = 8(6x-9)

28x + 28 = 48x - 72

72 + 28 = 48x - 28x

100 = 20x

x = 100/20

x = 5
