Use the Pythagorean theorem a^2 + b^2 = c^2

45^2 + 80^2 = c^2

2025 + 6400 = c^2

c^2 = 8425

c = √8425

c = 91.787

Rounded to the nearest foot = 92 feet

How can 17/20 and 7/4 make a sum of 9/10

Anika [276]

Answer:

the answer is $\frac{35}{20}$

Step-by-step explanation:

You have to find the common denominator in order to get the sum.

multiply 5 to $\frac{7}{4}$ and you get $\frac{35}{20}$

then to double check the sum, subtract it.

$\frac{35}{20}-\frac{17}{20}=\frac{9}{10}$

hope this make sense :/

Solve for b<br><br> B=??????

kozerog [31]

Answer:

$\frac{b-7}{b+1}=\frac{b-10}{b+4}$

$\left(b-7\right)\left(b+4\right)=\left(b+1\right)\left(b-10\right)$

$\left(b-7\right)\left(b+4\right)=b^2-3b-28$

$\left(b+1\right)\left(b-10\right)=b^2-9b-10$

$b^2-3b-28=b^2-9b-10$

$b^2-3b-28+28=b^2-9b-10+28$

$b^2-3b=b^2-9b+18$

$b^2-3b-\left(b^2-9b\right)=b^2-9b+18-\left(b^2-9b\right)$

$6b=18$

$\frac{6b}{6}=\frac{18}{6}$

$b=3$

PROBLEM 2 The height of a golf ball in feet can be determined using the formula h(t) = -16t2 + 100x , where t is the number of s

wolverine [178]

Answer:

Step-by-step explanation:

Given the height of a golf ball in feet modelled by the formula h(t) = -16t² + 100x where t is in seconds, we are to find the height of the golf after 2.5 seconds. To do that we will simply substitute t = 2.5secs into the formula given;

$h(t) = -16t^2 + 100x\\\\h(2.5) = -16(2.5)^2 + 100(2.5)\\\\h(2.5) = -16(6.25) + 250\\\\h(2.5) = -100+250\\\\h(2.5) = 150\\\\$

Hence the height of the golf after 2.5 seconds is 150ft.
