If he reads 4.5 pages a minute, which I assume is (4.5, 1) as an ordered pair, then he read 90 pages in 20 minutes (90, 20)

A toy company has determined that the revenue generated by a particular toy is modeled by the following equation: 10x - 0.025x²

Digiron [165]

Answer:

Maximum revenue = 1000 thousands of dollars.

Explanation:

We have the revenue equation $r(x)=10x - 0.025x^2$ , where x is measured in thousands of toys produced, and r(x) is measured in thousands of dollars.

At maximum revenue the derivative of equation is zero

So, $r'(x)=0\\ \\10 - 0.025*2x=0\\ \\ x=10/0.05\\ \\ x=1000/5=200$

So maximum revenue is when 200 thousands of toys are produced.

Maximum revenue, $r(200)=10*200 - 0.025*200^2\\ \\ r(200)=1000$

Maximum revenue = 1000 thousands of dollars.

What type of triangle is triangle ABC give reasons for your answer help please I need 1 more mark But I don't know what I'm doin

ladessa [460]

Answer: isosceles

Step-by-step explanation:

By the alternate interior angles theorem, $\angle CAB=50^{\circ}$

Since angles in a triangle add to 180 degrees, $\angle ACB=180^{\circ}-80^{\circ}-50^{\circ}=50^{\circ}$

Since sides opposite equal angles in a triangle are equal, $AB=BC$ .

So, triangle ABC is <u>isosceles</u>

givi [52]

Answer:

<u>13 inches</u>

Step-by-step explanation:

<u>Area of fabric</u> : 117 square inches
<u>Height</u> : 18 inches

Base x Height x 1/2 = Area (Fabric)
Base x 18 x 1/2 = 117
Base x 9 = 117
Base = <u>13 inches</u>
