Hello from MrBillDoesMath!

Answer: b = 4, h = 13

Discussion:

For a triangle with base b" and height "h, the area formula is

A= (1/2)bh.

In our case A = 26, h = 5b-7, so

26 = (1/2) b (5b-7). Multiply both sides by 2:

26*2 = b(5b-7) =>

52 = b(5b-7) =>

52 = 5b^2 - 7b => (subtract 52 from both sides)

5b^2 - 7b - 52 = 0. This factors as follows:

(b - 4) (5 b + 13) = 0 (use quadratic formula to find this)

so b = 4 and h = 5b -7 = 5*4 - 7 = 13

Thank you,

MrB

The altitude of a triangle is increasing at a rate of 3 centimeters/minute while the area of the triangle is increasing at a rat

sp2606 [1]

The base of the triangle is decreasing at a rate of 3.60 centimeters/minute.

According to the statement

we have to find that the rate at which the base of triangle changing.

So, For this purpose,

Area of triangle: A = (1/2)(b * h)

Related Rates - Derivative with respect to time:

(d/dt)[A = (1/2)(b * h)]

Then

dA/dt = (1/2)[b * dh/dt + h * db/dt]

Given: h = 11 centimeters, A = 91 square centimeters, b = ??

A = (1/2)(b * h)

Then it becomes

b = 2A/h

substitute the value then

b = 2(91)/11

b = 16.54 centimeters

Then

h = 11 centimeters, b = 16.54 centimeters, dA/dt = 5 square centimeters/minute, dh/dt = 3 centimeters/minute, db/dt = ?? centimeters/minute

So,

(d/dt)[A = (1/2)(b * h)]

Then it become

dA/dt = (1/2)[b * dh/dt + h * db/dt]

5= (1/2)[16.54 * 3 + 11 * db/dt]

5= 49.62/2 + 11/2 * db/dt

11/2 * db/dt = 5- 49.62/2

5.5*db/dt = 5 - 24.81

db/dt = -19.81/5.5

db/dt = -3.60 centimeters/minute

So, The base of the triangle is decreasing at a rate of 3.60 centimeters/minute.

The function M(s) = 225 + 0.65s represents the material cost of manufacturing gardening scissors when s scissors are produced. T

Llana [10]

Answer:

$\frac{279 + 1.8s}{s}$

Step-by-step explanation:

The material cost of manufacturing gardening scissors when s scissors are produced : $M(s) = 225 + 0.65s$

The labor cost for producing s scissors: $L(s) = 54 + 1.15s$

So, total cost of producing s scissors = $M(s)+L(s)$

= $225 + 0.65s+54 + 1.15s$

= $279 + 1.8s$

So, total cost for s scissors = $279 + 1.8s$

So, manufacturing cost for 1 scissor= $\frac{279 + 1.8s}{s}$

Hence the manufacturing cost per scissors is $\frac{279 + 1.8s}{s}$
