Step-by-step explanation:
Answer:
a = -6
b = 1
Step-by-step explanation:
The gradient of the tangent to the curve y = ax + bx^3, will be:
dy/dx = a + 3bx²
at (2, -4)
dy/dx = a+3b(2)²
dy/dx = a+12b
Since the gradient at the point is 6, then;
a+12b = 6 ....1
Substitute x = 2 and y = -4 into the original expression
-4 = 2a + 8b
a + 4b = -2 ...2
a+12b = 6 ....1
Subtract
4b - 12b = -2-6
-8b = -8
b = -8/-8
b = 1
Substitute b = 1 into equation 1
Recall from 1 that a+12b = 6
a+12(1) = 6
a = 6 - 12
a = -6
Hence a = -6, b = 1
Answer:
$9.6
Step-by-step explanation:
The computation of the price of the mixture is shown below:
The price of candy is
= 3 lbs × $1.7 per pound
= $5.1
And for other the price is
= 5 × 0.90
= $4.5
So, the total price of the mixture be
= $5.1 + $4.5
= $9.6
Answer:
Step-by-step explanation:
first athlete =28.65
second athlete=24.25
the first athlete jump - second athlete jump
28.65-24.25
= 4.40
the first athlete long jump then the second athlete
To solve for x you have to get x by itself. multiply both sides by 6. this will leave you with 12 = x
