For 9, we have multiplying (multiplication) of h and the sum (addition of base1 and base2). Since it doesn't say to multiply them individually, we have h*(base1+base2)

For 10, we have the surface area = 2 times pi * r^2 (the square of the radius) plus the product (multiplication) of pi, the radius, and the height =
2*(pi*r^2)+(pi*r*h)

Write an equation for the

Travka [436]

Answer:

See below

Step-by-step explanation:

For the model function $f(x)=a|x-h|+k$ , $(h,k)$ is the vertex, and $a$ is the horizontal growth or shrink factor.

We know that our vertex is $(-1.5,0)$ from our graph, so we'll need to determine the value of $a$ by using one of the points on the graph:

$f(x)=a|x-h|+k\\\\f(x)=a|x-(-1.5)|+0\\\\f(x)=a|x+1.5|\\\\f(0)=a|0+1.5|\\\\3=a|1.5|\\\\3=1.5a\\\\2=a$

Thus, our equation for the given graph is $f(x)=2|x+1.5|$ .

The domain of a function is the set of all existing real x-values, thus, our domain for the given function is $(-\infty,\infty)$ , or all real x-values.

The range of a function is the set of all existing real y-values, thus, our range for the given function is $[-1,\infty)$ , or all real y-values starting with y=-1 which is included.

Radius OB measures x units. Which expression represents

777dan777 [17]

Answer:

Circumference of the smaller circle = 2.1x units

Step-by-step explanation:

Given question is incomplete; here is the complete question.

Two similar circles are shown. The circumference of the larger circle, with radius OB, is 3 times the circumference of the smaller circle, with radius OA. Radius OB measures x units. Which expression represents the circumference of the smaller circle with radius OA ?

Radius of the larger circle OB = x units

Radius of the smaller circle OA = y units

Circumference of larger circle = 2πx units

Circumference of smaller circle = 2πy units

Since circumference of larger circle is 3 times the circumference of smaller circle,

2πx = 3(2πy)

2πx = 6πy

x = 3y

y = $\frac{x}{3}$

Therefore, circumference of the smaller circle = $2\pi (\frac{x}{3})$ units

= $\frac{2\pi x}{3}$ units

= 2.094x

≈ 2.1x

Circumference of the smaller circle circle = 2.1x units
