Equation B: 2x+3x-6 is accurate
Answer:
A: x2+3x-6=x+2
Step-by-step explanation:
A: x2+3x-6=x+2
x2+3x-x-6-2=0
x2+2x-8=0
(x+4)(x-2)=0
x=-4, x=2
B:x2+3x-6=3x+2
x2+3x-3x-6-2=0
x2-8=0

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.
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

A car dealership decreased the price of a certain car by 12%. The original price was $37,400.
(a) Fill in the blank to write the new price in terms of the original price. Write your answer as a decimal.
New=price × Originalprice
(b) Use your answer in part (a) to determine the new price.
Newprice:$
Answer:
$32912
Step-by-step explanation:
new price = price decrease × original price
new price = 0.88 × 37400
37400 decrease 12% =
37400 × (1 - 12%) = 37400 × (1 - 0.12) = 32912

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.

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°
