The function given is an exponential function as the slope constantly changes

To solve this problem, we simply need to determine if the relationship is linear or not or if its a proportional relationship.

Taking two points;

6/0.25 = 11/0.5

24 = 22

The relationship is not proportional.

Let's try and determine if it has a linear relationship.

To do this, we need to calculate for the slope.

Taking two points again;

m = y2 - y1 / x2 - x1

m = 11 - 6 / 0.5 - 0.25

m = 20

Taking another two points again;

m = y2 - y1 / x2 - x1

m = 18 - 11 / 1.0 - 0.5

m = 14

This is most likely an exponential function as the slope constantly changes.

Answer:

The numbers are 1/2 and 17/2

Explanation:

Let the two numbers be represented by a and b.

Given that

Their sum is 9, we have:

a + b = 9 ......................................................................................(1)

Their difference is -8, then

a - b = -8 .......................................................................................(2)

To know the values of the numbers a and b, we need to solve the equations (1) and (2) simultaneously.

From (2)

a = b - 8 .......................................................................................(3)

Using equation (3) in (1)

b - 8 + b = 9

2b - 8 = 9

Add 8 to both sides

2b - 8 + 8 = 9 + 8

2b = 17

Divide both sides by 2

b = 17/2 ......................................................................................(4)

Using (4) in (3)

a = 17/2 - 8

a = 1/2

Keep in mind that without the population standard deviation, it is impossible to provide an exact sample size. However, this formula will give you a good starting point.

To find the sample size needed for a 99.5% confidence interval with a margin of error of 1.5, we can use the formula:

n = (Z * σ / E)^2

where n is the sample size, Z is the Z-score corresponding to the desired confidence level, σ is the population standard deviation, and E is the margin of error.

For a 99.5% confidence interval, the Z-score is approximately 2.807 (from a standard normal distribution table). Since we do not have the population standard deviation (σ), we will need to estimate it using a sample standard deviation or use a conservative approach by assuming the maximum possible value. For now, let's assume we have an estimated standard deviation.

n = (2.807 * σ / 1.5)^2

Solve for n by plugging in the estimated standard deviation (σ) and then round up to the nearest whole number, as you cannot have a fraction of a sample.

The output value of (f∘g)(x) is:  \((f \circ g)(x) = \frac{4x^2-29x+60}{x +3}\)

The domain of (f∘g)(x) is (-∞, -3) U (-3, ∞).

In this scenario, we would determine the corresponding composite function of f(x) and g(x) under the given mathematical operations (multiplication) in simplified form as follows;

\(f(x) = \frac{x-6}{x +3}\)

g(x) = 4x - 15

Next, we would write the numerators and denominators in factored form as follows;

(x - 6)(4x - 15)

4x² - 15x - 24x + 60

4x² - 29x + 60

Now, we can derive the corresponding composite function of f(x) and g(x);

\((f \circ g)(x) = \frac{4x^2-29x+60}{x +3}\)

For the restrictions on the domain, we would have to equate the denominator of the rational function to zero and then evaluate as follows;

x + 3 ≠ 0

x ≠ -3

Domain = (-∞, -3) U (-3, ∞).

60/14 =127.8/X cross multiply

60X= 14×127.8

X=( 14×127.8)÷60

X= 29.82 miles

Answer: The answer to your question is C. Brainliest?

Step-by-step explanation:

For the first square, we can multiply both the numerator and denominator by 5 to get an equivalent fraction with a denominator of 60:

2/12 = (2 x 5) / (12 x 5) = 10/60

For the second square, we can multiply both the numerator and denominator by 4 to get an equivalent fraction with a denominator of 60:

2/15 = (2 x 4) / (15 x 4) = 8/60

Now, we can add the two fractions:

10/60 + 8/60 = 18/60

Simplifying this fraction by dividing both numerator and denominator by 6, we get:

18/60 = 3/10

Therefore, the total shaded area in the diagram is 3/10 or 0.3 in decimal form.

The answer is C. 0.3.

Step-by-step explanation:

Let M = Event of getting an A in Marketing class.

S = Event of getting an A in Spanish class,

i.e. P(M) = 0.80 , P(S) = 0.60 and P(M∩S)=0.45

Required probability = P(neither M nor S)

= P(M'∩S')

= P(M∪S)'                                 [∵P(A'∩B')=P(A∪B)']

=1- P(M∪S)                               [∵P(A')=1-P(A)]

= 1- (P(M)+P(S)- P(M∩S))   [∵P(A∪B)=P(A)+P(B)-P(A∩B)]

= 1- (0.80+0.60-0.45)

= 1- 0.95

= 0.05

hence, the probability that Helen does not get an A in either class= 0.05

The correlation between the obesity rate and the mortality rate is moderately strong.

Step-by-step explanation:

side BC = side AB

so their base angles that is ∠A = ∠C = (3x+20)°

now, total measure of the angles of a triangle is 180° & ∠B = x°

Now,

m∠A + m∠B + m∠C = 180

⇒ 3x + 20 + x + 3x + 20 = 180

⇒ 7x + 40 = 180

⇒ 7x = 140

⇒x = 20

The property illustrated in equation 4(-8+5) = -32 + 20 is the Distributive Property.

The Distributive Property states that when a number is multiplied by a sum or difference in parentheses, it can be distributed or multiplied by each term inside the parentheses separately, and then the results can be added or subtracted.

In this case, the number 4 is multiplied by the sum (-8 + 5). By applying the Distributive Property, we distribute the 4 to each term inside the parentheses:

4(-8 + 5) = (4 * -8) + (4 * 5)

This simplifies to:

4(-8 + 5) = -32 + 20

Finally, we can perform the addition:

-32 + 20 = -12

Therefore, the equation demonstrates the application of the Distributive Property.

Step-by-step explanation:

The intercepts of the car depreciation equation are (0, 32000) and (12, 0).

Equations can also be written in different forms, such as standard form, slope-intercept form, and point-slope form, depending on the context and the specific problem being solved. Additionally, equations can be manipulated and solved using a variety of techniques, including algebraic manipulation, factoring, substitution, and graphing.

If the car depreciates in a straight line form, we can assume that its value decreases linearly over time. Let's use the point-slope form of a linear equation to find the depreciation equation:

y - y1 = m(x - x1)

where y is the value of the car, x is the number of years since it was purchased, m is the rate of depreciation per year, and (x1, y1) is a point on the line.

We know that the car is worth $32,000 when it is purchased (i.e., at x = 0), so we can use this as our point (x1, y1). We also know that the car has no marketable value after 12 years (i.e., at x = 12), so we can use this as another point on the line.

Using the two points, we have:

y - 32000 = m(x - 0)

y - 0 = m(x - 12)

Simplifying these equations, we get:

y = mx + 32000

y = mx

Setting the right-hand sides of these equations equal to each other, we get:

mx + 32000 = mx

Solving for x, we get:

32000 = mx

x = 32000/m

Since the car loses all of its marketable value after 12 years, we know that the value of the car is 0 at x = 12.

0 = m(12) + 32000

m = -2666.67

Now we can substitute m into our equation to get:

y = -2666.67x + 32000

To find the intercepts of the depreciation equation, we set y = 0 and solve for x:

0 = -2666.67x + 32000

2666.67x = 32000

x = 12

So one intercept is at x = 12, which we already knew. To find the other intercept, we set x = 0 and solve for y:

y = -2666.67(0) + 32000

y = 32000

Therefore, the intercepts of the depreciation equation are (0, 32000) and (12, 0).
