Can use the Pythagorean theorem to solve for b if c is 13 and a is 12

Greeley [361]

Answer:b=5

Step-by-step explanation:the formular for pythagoras theory is

C^2=a^2+b^2

13^2=12^2+b^2

169=144+b^2

Collect like terms

169-144=b^2

b^2=25

Take the the square root of both sides

b=square root of 25

An evergreen nursery usually sells a certain shrub after 5 years of growth and shaping. The growth rate during those 5 years is

ivanzaharov [21]

Answer:

$h(t) = 0.75t^2 + 4t + 12$

Step-by-step explanation:

The equation given calculates the derivative of the height in relation to the time, that is, the rate of change of the height. To find the equation for the height, we need to integrate this equation:

$dh/dt = 1.5t + 4$

Multiplying both sides by 'dt', we have:

$dh = (1.5t + 4)dt$

Using the integral in both sides:

$\int dh = \int (1.5t + 4) dt$

$h = 0.75t^2 + 4t + h(0)$

$h = 0.75t^2 + 4t + 12$

So the height after t years is represented by this equation:

$h(t) = 0.75t^2 + 4t + 12$

How do u write 4 1/4 in simplest form and not in decimals I haven't learned that yet .

alexandr1967 [171]

It already is in simplest form because the numerator and denonimator don't have a common factor to then divide them by.

Golfer had the lowest number of strokes per hole is Alicia  = 4.

Step-by-step explanation:

We have , Three different golfers played a different number of holes today. Rory played 999 holes and had a total of 424242 strokes. Alicia played 181818 holes and had a total of 797979 strokes. Rickie played 272727 holes and had a total of 123123123 strokes. We have to find , Which golfer had the lowest number of strokes per hole :

Rory:

Number of strokes per hole = $\frac{424242}{999} = 425$

Alicia:

Number of strokes per hole = $\frac{797979}{181818} = 4$

Rickie:

Number of strokes per hole = $\frac{123123123}{272727} = 451$

∴ Golfer had the lowest number of strokes per hole is Alicia  = 4.
