What is the multiplicative rate of change for the exponential function graphed to the left?
Answers
As, the values on the x-axis changes, the value of y-axis gets tripled,the rate of change of values of response with respect to the domain is 3. Hence, the multiplicative rate of change of the exponential function is 3.
Given information:
The graph of an exponential function is having the different rate of change of function with respect to the values of x and y.
The values given for the function are ,
[tex]f(-2)=2/9\\f(-1)=2/3\\f(0)=2\\f(1)=6\\f(2)=6\\f(3)=54\\[/tex]
As, the given function is having a growth on every point which is multiplicative, hence the multiplicative rate of change for the exponential function can be calculated.
According to the points given, the rate of change of values of response with respect to the domain is 3,
Hence, the multiplicative rate of change of the exponential function is 3.

It takes Susan 3 hours to fix 2 broken cars and it takes Joseph 4 hours to fix 3 broken cars. If they work together how long will it take them to fix 17 broken cars?
Answers
Susan = 2 car / 3 hr
= 2/3
Joe = 3 car / 4 hr
= 3/4
add the rates to get the new combined rate as 17 cars in "t" hours.
2/3 + 3/4 = 17/t
Need common denominator
2/3(4/4) + 3/4(3/3) = 17/t
8/12 + 9/12 = 17/t
17/12 = 17/t
see that "t" is 12 hours
Susan and Joseph can fix 17 broken cars together in 12 hours.
Explanation:To calculate the time it takes for Susan and Joseph to fix 17 broken cars together, we can calculate their individual rates of work.
Susan takes 3 hours to fix 2 cars, so her rate is 2/3 cars per hour.
Joseph takes 4 hours to fix 3 cars, so his rate is 3/4 cars per hour.
When they work together, their rates are additive. So their combined rate is (2/3 + 3/4) cars per hour. This is equal to (8/12 + 9/12) cars per hour, which simplifies to 17/12 cars per hour.
To find the time it takes to fix 17 cars, we can divide the number of cars by the combined rate: 17 cars / (17/12 cars per hour) = 12 hours.

Derek's phone number, $336$ - $7624,$ has the property that the three-digit prefix, $336,$ equals the product of the last four digits, $7 \times 6 \times 2 \times 4.$ how many seven-digit phone numbers beginning with $336$ have this property?
Answers
To find the number of seven-digit phone numbers beginning with 336 that have the given property, we need to determine the number of possible combinations for the middle three digits. The number of different seven-digit phone numbers that satisfy the given property is 7.
Explanation:To find the number of seven-digit phone numbers beginning with 336 that have the given property, we need to determine the number of possible combinations for the middle three digits.
The last four digits of the phone number are the product of 7, 6, 2, and 4, which is 336.
Since the three-digit prefix is also 336, the remaining three digits in the middle should be such that their product is also 336.
336 can be factored as 2 x 2 x 2 x 2 x 3 x 7. So, we need to find the number of ways to distribute these factors over the three middle digits.
Since the digits cannot be repeated, we can list down all the possibilities:
2 x 2 x 7
2 x 4 x 3
2 x 2 x 3 x 2
4 x 2 x 3
3 x 2 x 2 x 2
2 x 3 x 2 x 2
2 x 2 x 2 x 3
Each of these combinations can be arranged in different ways, resulting in multiple seven-digit phone numbers.
Therefore, there are 7 different seven-digit phone numbers beginning with 336 that have the given property.Learn more about Phone Numbers here:

A square prism has a base with the length of 23 cm. What is the area, in square centimeters, of the base of the prism?
Answers
Your friend wants to borrow $1,137.45 from you to pay off a credit card that charges a 14.7% APR. You agree to the loan but require your friend to pay you interest of 3.6% APR on the loan and your friend agrees.
Your friend pays you $200.00 at the end of the first month. How much goes toward the principal?
Answers
Let's start by calculating the interest on the first month. 1137.45 * (0.036/12) = 1137.45 * 0.003 = 3.41235
So at the end of the 1st month, the amount owed will be 1137.45 + 3.41 = 1140.86
And after the 200 payment is done, the new balance will be:
1140.86 - 200 = 940.86
Meaning that the principle reduced is: 1137.45 - 940.86 = 196.59
We could have also gotten the amount going towards the principle by subtracting the interest from the paying like: 200 - 3.41 = 196.59
The amount that goes into the principal when friend pays you $200.00 at the end of the first month is $296.56.
How to calculate the amount?The first interest will be:
= 1137.45 × (0.036/12)
= 3.41
The amount owed at the month end will be:
= 1137.45 + 3.41
= 1140.86
The new balance after 200 payment will be:
= 1140.86 - 200
= 940.86
Therefore, the reduction in principal will be:
= 1137.45 - 940.86
= 196.59

The angles opposite the congruent sides of an isosceles triangle are congruent find the value of x in the triangle TRIANGLE BOTTOM LEFT OF TRIANGLE 70 DEGREES VERY TOP OF TRIANGLE X!!!! PLS HELP WITHOUT COPY AND PASTING. SHOW ALL UR WORK
Answers
Final Answer:
In the isosceles triangle, the base angles are congruent, and the given angle at the top is [tex]\(70^\circ\)[/tex]. Using the sum of angles in a triangle, we find that the value of (x) is [tex]\(40^\circ\)[/tex]. Therefore, the final answer is [tex]\(x = 40^\circ\)[/tex].
Step-by-step explanation:
The base angles of the isosceles triangle as (A) and (B), and the vertex angle as (x). Since we know that the angles opposite the congruent sides are congruent, we have:
[ A = B ]
Now, let's consider the sum of angles in a triangle. The sum of all angles in a triangle is always [tex]\(180^\circ\)[/tex]. Therefore:
[tex]\[ A + B + x = 180^\circ \][/tex]
But since (A = B), we can rewrite this as:
[tex]\[ 2A + x = 180^\circ \][/tex]
Now, substitute (A) with [tex]\(70^\circ\)[/tex] (as given in the problem):
[tex]\[ 2(70^\circ) + x = 180^\circ \][/tex]
Simplify the equation:
[tex]\[ 140^\circ + x = 180^\circ \][/tex]
Now, isolate (x) by subtracting [tex]\(140^\circ\)[/tex] from both sides of the equation:
[tex]\[ x = 180^\circ - 140^\circ \][/tex]
[tex]\[ x = 40^\circ \][/tex]
So, the value of (x) in the given isosceles triangle is [tex]\(40^\circ\)[/tex].
Final answer:
The value of x in the isosceles triangle is 40 degrees, which is found by using the property that the angles opposite the congruent sides are congruent and the sum of the angles in any triangle is always 180 degrees.
Explanation:
To find the value of x in an isosceles triangle where one of the angles at the base is 70 degrees, we employ the property that the angles opposite the congruent sides of an isosceles triangle are also congruent. This means that the other angle at the base is also 70 degrees. Since the sum of the angles in any triangle is always 180 degrees, we can set up an equation to solve for x:
70° (angle at the left base) + 70° (angle at the right base) + x (angle at the top) = 180°
Adding the base angles together gives us:
70° + 70° = 140°
To find x, we simply subtract the sum of the base angles from 180 degrees:
180° - 140° = 40°
Therefore, the value of x, the angle at the top of the isosceles triangle, is 40 degrees.

multiply the term number by 2, subtract 1 from the result, multiply by 2 times the term number, and divide the result by 2.
if term number is x,
the number in the pattern for xth term is ;
multiply term number by 2 - 2x
subtract 1 - 2x - 1
multiply by 2 times the term number - (2x-1) * 2x
divide by 2 - ((2x-1) * 2x)/2
so first term x=1
((2*1-1) * 2*1)/2
2/2 = 1
second term x = 2
((2*2-1) * 2*2)/2
(3*4)/2 = 6
third term x = 3
((2*3-1) * 2*3)/2
5*6/2 = 15

Angle C < Angle B < Angle A
