Answer:
m=-4, b=3
Step-by-step explanation:
Answer:
y = 3
Step-by-step explanation:
Substitute the given points into the function and solve for a and b
Using (2, 12)
12 = ab² → (1)
Using (5, 96)
96 = a → (2)
Divide (2) by (1)
= , that is
b³ = 8 ( take the cube root of both sides )
b = = 2
Substitute b = 2 into (1) and solve for a
12 = a2² = 4a ( divide both sides by 4 )
3 = a
Thus
y = 3 ← is the exponential function
1 2/5 pounds multiplied by 5 baskets is 7 pounds of berries. 7 pounds subtract 2 1/4 pounds is 4 3/4 pounds. Her estimation is reasonable because 4 3/4 pounds is about 5 pounds.
The answer is N-7......................................
Simple interest is $ 9
<em><u>Solution:</u></em>
Given that,
P = $ 400
T = 0.25 years
<em><u>The formula for simple interest is:</u></em>
Where,
I is the simple interest earned
R is the rate of interest in decimal
T is the number of years
<em><u>Substituting the values we get,</u></em>
Thus simple interest is $ 9
