Answer:
<h2>a) 0.5367feet</h2><h2>b) 0.5223feet</h2><h2>c) 0.7292feet</h2>
Step-by-step explanation:
Given the rate at which an eucalyptus tree will grow modelled by the equation 0.5+6/(t+4)³ feet per year, where t is the time (in years).
The amount of growth can be gotten by integrating the given rate equation as shown;
a) The number of feet that the tree will grow in the second year can be gotten by taking the limit of the integral from t =1 to t = 2
b) The number of feet that the tree will grow in the third year can be gotten by taking the limit of the integral from t =2 to t = 3
c) The total number of feet grown during the second year can be gotten by substituting the value of limit from t = 0 to t = 2 into the equation as shown
Answer:
A
Step-by-step explanation:
Given
x² - x = 30
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- )x + = 30 +
(x - )² =
Take the square root of both sides
x - = ± = ±
Add to both sides
x = ± , thus
x = - = - 5
x = + = 6
Answer:
your number is 18
Step-by-step explanation:
x^2 = (x × 10 ) + 144
x^2 = 10x + 144
x^2 - 10x - 144 = 0
using quadratic method
your answer should be
(x- 18) ( x+8 )
Answer:
144 push-ups
Step-by-step explanation:
hii
assuming they did the same amount of pushups every day:
112 pushups in 14 days
112p : 14d
xp : 18d
14 ÷ 7 =2
2 × 9 = 18
do the same do the pushups ( ÷7 and ×9)
112 ÷ 7 = 16
16 ×9 = 144
should be 144 pushups
hope this helps :)
Plug -2 in for x and -5 in for y.
A. 1 - 2(-2) + 3(-5) = -10
B. - |(-2) - (-5)| = -3
C. Sqrt((-2)^2) + cubert((-5)^3) = -7
D. 1/2(-2) + 1/3(-5) = -8/3
