Answer:
length 15 width 9
Step-by-step explanation:
Then the length can be represented by the following expression: (x + 6)
Since area is equal to length times width, we can write the following equation for the area:
A = length * width
135 = (w + 6) * w
Now we can solve for w after using the distributive property and factoring:
135 = (w + 6) * w
135 = w^2 + 6w
0 = w^2 + 6w - 135
This factors to:
0 = (w + 15) (w -9)
w = -15 OR w = 9

The radius of a sphere is increasing at a rate of 4 mm/s. How fast is the volume increasing (in mm^3/s) when the diameter is 60 mm
Answer:
The volume is increasing at a rate of 1508 cubic millimeters per second when the diameter is 60 mm.
Step-by-step explanation:
Volume of a sphere:
The volume of a sphere is given by the following equation:
[tex]V = \frac{4\pi r^3}{3}[/tex]
In which r is the radius.
Implicit derivatives:
This question is solving by implicit derivatives. We derivate V and r, implicitly as function of t. So
[tex]\frac{dV}{dt} = 4\pi r^2 \frac{dr}{dt}[/tex]
The radius of a sphere is increasing at a rate of 4 mm/s.
This means that [tex]\frac{dr}{dt} = 4[/tex]
How fast is the volume increasing (in mm^3/s) when the diameter is 60 mm?
This is [tex]\frac{dV}{dt}[/tex] when [tex]r = \frac{d}{2} = \frac{60}{2} = 30[/tex]. So
[tex]\frac{dV}{dt} = 4\pi r^2 \frac{dr}{dt}[/tex]
[tex]\frac{dV}{dt} = 4\pi*(30)^2*4[/tex]
[tex]\frac{dV}{dt} = 1508[/tex]
The volume is increasing at a rate of 1508 cubic millimeters per second when the diameter is 60 mm.

given h(x) = 5x -1, find h(1).
The required value of h(1) for the function h(x) = 5x -1 is 4.
Given that,
A polynomial function is given h(x) = 5x -1, it value at x = 1 ios to be determined.
Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
What is a polynomial function?A polynomial function is a function that applies only integer dominions or only positive integer powers of a value in an equation such as the quadratic equation, cubic equation, etc. ax+b is a polynomial.
Here, according to the question
function h(x) = 5x -1
at x = 1
h(1) = 5(1) - 1
= 5 - 1
= 4
Thus, the required value of h(1) for the function h(x) = 5x -1 is 4.

4. Cassie has a total of 110 coins in her piggy bank. All the coins are q
total value of $20.30. How many quarters and how many dimes are
Solution:
Reply Reply all Forward
Answer:
b
Step-by-step explanation:
its easy
Answer:
there are 62 quarters and 48 dimes
Step-by-step explanation:
d + q = 110......d = 110 - q
0.10d + 0.25q = 20.30
0.10(110 - q) + 0.25q = 20.30
11 - 0.10q + 0.25q = 20.30
-0.10q + 0.25q = 20.30 - 11
0.15q = 9.30
q = 9.30/0.15
q = 62 <==== there are 62 quarters
d = 110 - q
d = 110 - 62
d = 48 <==== there are 48 dimes

What is a circle?It is a locus of a point drawn an equidistant from the center. The distance from the center to the circumference is called the radius of the circle.
A ΔGRV is inscribed in a circle as shown in the figure below.
In ΔGRV, GR is congruent to GV.
Then the angle ∠V and ∠R are also equal.
The sum of the angle of the triangle is 180 degrees. Then angles ∠V and ∠R will be
∠V = ∠R = 80°
We know theorem
An arc of a circle subtends twice the angle it subtends anywhere on the circle's circumference at its center.
Then the measure of the angle GR will be
→ 2 × 80°
→ 160°
