What is exponential equation that has a y-intercept of 5 and a multiplier of 1.7

The answer is 18

You first multiply both sides by 6 which will make 15, now 90

then divide both sides by 5 so that will make 90, 18 thus x=18 is correct

As it is a proportional relationship then this relationship can be described by a line. To find the equation of the line that passes through the points shown in the table, you can first find the slope and then use the point-slope formula.

The range will be impacted by A. The range will increase by 12.

A range simply means the difference between the highest and the lowest number.

Highest number = 34

Lowest number = 15

Range = 34 - 15 = 19

When the highest number is 46, the range will be:

= Highest number - Lowest number

= 46 - 15

= 31

The difference will be:

= 31 - 19

= 12

The average rate of change of the function f(x) on the interval−6≤x≤2 is  -0.5

This is further explained below.

Generally, The average rate of reaction is referred to as the change in concentration of any of the reactants or any of the products per unit of time during a specific period of time. This change may occur at any point throughout the reaction.

A single rate is applicable to property that is located in more than one place and that is calculated by weighting the separate rates that are calculated for each location.

The approximate surface area of the right triangular prism is 141.5 cm².

The surface area of a triangular prism can be found as follows;

surface area of a triangular prism = (perimeter × length) + (2 × base area)

Therefore,

perimeter of the triangular base = 5 + 5 + 5

perimeter of the triangular base = 15 cm

length = 8 cm

The base area = 1 / 2 bh

where,

The base area = 1 / 2 × 4.3 × 5

The base area = 1 / 2 × 21.5

The base area = 10.75 cm²

Hence,

surface area of a triangular prism = (15 × 8) + 2(10.75)

surface area of a triangular prism = 21.5 + 120

Answer : r = 3%

Answer:

100 is the number

Step-by-step explanation:

For this equation, it may be helpful to replace words with symbols.
The question is:
if 6% of x is the same as 5% of 120, then what is x?

The comma splits the sentence into two parts

if 6% of x is the same as 5% of 120 is the main focus, and the second part requires you to find x.

In the question "if 6% of x is the same as 5% of 120"
the word "of" can be replaced with " * ", and the words "is the same as" can be replaced with "=". The if can be dropped

The question becomes:

6% * x = 5% * 120

This equation can be easily solved.

6% = 0.06
5% = 0.05

So,

0.06x=0.05*120

0.06 x = 6

x = 6 / 0.06

x = 100

In a population of values having a normal distribution with (μ = 62.9) and (σ = 25.8), and we intend to draw a random sample of size (n = 22),

(i) The probability that a single randomly selected value is less than 45.3 [P(X < 45.3) is 0.2476

(ii) The probability that a sample of size (n = 22) is randomly selected with a mean less than 45.3 [P(M < 45.3)] is (0.0007)

As per the question statement, a population of values has a normal distribution with (μ = 62.9) and (σ = 25.8) and we intend to draw a random sample of size (n = 22).

We are required to calculate:

(i) The probability that a single randomly selected value is less than 45.3 [P(X < 45.3)

(ii) The probability that a sample of size (n = 242) is randomly selected less than 45.3 [P(M < 45.3)].

Let us assume that, a random variable "X" follows normal distribution with mean (μ = 62.9), standard deviation (σ = 25.8) and a sample size of (n = 22).

(i) The probability that a single randomly selected value is less than 45.3 [P(X < 45.3) is,

P (X < 45.3) = P[{(X - μ)/σ} < {(45.3 - 62.9)/25.8}]

= [P{Z < (-0.6822)}]

=0.247556247343...[Using Excel Function "NORMSDIST (-0.6822)]

≈ 0.2476

(ii) The probability that a sample of size (n = 22) is randomly selected with a mean less than 45.3 [P(M < 45.3)] is,

P(M < 45.3) = P[{(M - μ)/(σ/√n)} < {(45.3 - 62.9)/25.8/√22)}]

= P[{(M - μ)/(σ/√n)} < {(45.3 - 62.9)/5.5006}]

Simple interest is the cost of borrowing money without accounting for the effects of compounding.12672 is the size of Kathleen’s total interest when she retires.

Simple interest is the cost of borrowing money without accounting for the effects of compounding.

Given that Kathleen begins working and at age 32 she invests $6000.00 into a retirement account that pays an APR of 6.4% compounded monthly. She expects to retire at age 65.

Let us calculate the age or time

65-32 =33 years

A=P(1+rt)

A= Final Amount

P=Principle amount=6000

r = rate of interest=6.4%

t is time =33 years

Substitute these values in Formula.

Convert 6.4% to decimal number by dividing with 100.

A=6000(1+0.064(33))

A=6000(1+2.112)

A=6000(3.112)

A=18672

The final Amount she got is 18,672.

To find the interest amount we have to substitute initial amount from final amount.

18672-6000

=12672

Hence 12672 is the size of Kathleen’s total interest when she retires.

Answer

a) The plotted graph is shown in the Explanation below.

b) a = 12, b = 2

Explanation

n = a(b^m)

Taking the logarithm of both sides

log n = log [a(b^m)]

log n = log a + log (b^m)

log n = log a + m log b

So, to first plot the graph, we know we need to rewrite this equation to match the equation of a straight line. Equation of a straight line is

y = mx + b

where

y = y-coordinate of a point on the line.

m = slope of the line.

x = x-coordinate of the point on the line whose y-coordinate is y.

b = y-intercept of the line.

log n = (log b) m + log a

y = mx + b

y-axis = log n

slope = log b

x-axis = m

intercept = log a

So, we need to plot log n (on the y-axis) against m (on the x-axis)

m | n | log n

1 | 24 | 1.38

2 | 48 | 1.68

3 | 96 | 1.98

4 | 192 | 2.28

5 | 384 | 2.58

The values for log n are then plotted against the corresponding value of m

The image is presented below.

From the graph, we can easily see that

Intercept = 1

To obtain the slope, for a straight line, the slope of the line can be obtained when the coordinates of two points on the line are known. If the coordinates are (x₁, y₁) and (x₂, y₂), the slope is given as

Using the two farthest points,

(x₁, y₁) and (x₂, y₂) = (1, 1.38) and (5, 2.58)

b) Intercept = log a = 1.08

a = log⁻¹ (1.08) = 12

Slope = log b = 0.3

b = log⁻¹ (0.3) = 1.995 = 2

n = 12 (2^m)

We can test this by putting values of m in the expression looking to get n

when m = 1,

n = 12 (2^1)

n = 12 (2) = 24

when m = 5

n = 12 (2^5)

n = 12 (32) = 384

So, our model works!!!

Hope this Helps!!!
