Answer:

∠ABC = 98°

Step-by-step explanation:

an isosceles triangles base angles have the same angle measures

so both are 71

add them and then subtract that from 180 to find ∠ABD

180 - (71 + 71)

180 - 142 = 38

that is ∠ABD

to find ∠ABC you must add ∠DBC to ∠ABD

all angles of an equilateral triangle are equivalent

they are also 60 degrees

so add 60 to 38

38 + 60 = 98

that is your answer

Applying the property of exponents, the remainder that the number 10^2023 leaves after division by 13 is 9.

The remainder is the amount left over after a division operation.

An exponent is a number that indicates how many times a base number is used as a factor in a multiplication expression.

From the property of exponent:

We can rewrite 10^2023 as (10^13)^155 * 10^8:

10^2023 = (10^13)^155 * 10^8

We can then use the property of exponents to simplify:

10^2023 = (10^(13*155)) * 10^8

Since 10^13 is congruent to 1 mod 13, 10^(13*155) is congruent to 1 mod 13 as well. Therefore, 10^2023 is congruent to 10^8 mod 13.

We can find the remainder by calculating 10^8 mod 13:

10^8 = 100000000

After dividing 100000000 by 13, we get a remainder of 9.

Hello,

I hope you and your family are doing well!

A) To find the annual growth rate between 1991 and 2008, we can use the compound interest formula:

S = P(1 + r)

Where S is the final value of the house, P is the initial value of the house, and r is the annual growth rate.

Plugging in the values from the problem, we get:

165,000 = 95,000(1 + r)

Dividing both sides of the equation by 95,000 gives:

1.737 = 1 + r

Subtracting 1 from both sides of the equation gives:

0.737 = r

The annual growth rate between 1991 and 2008 is 0.737.

B) To express the growth rate in percentage form, we can multiply it by 100%:

0.737 * 100% = 73.7%

So the annual growth rate between 1991 and 2008 was 73.7%.

C) To find the value of the house in the year 2011, we can use the compound interest formula again, with the initial value of the house set to the final value in 2008:

S = P(1 + r)

Plugging in the values from the problem, we get:

S = 165,000(1 + 0.737)

Solving for S gives:

S = 165,000 * 1.737 = 285,195

So the value of the house in the year 2011 will be approximately $285,195. Rounded to the nearest thousand dollars, this is $285,000

Fill in y1 and x1 with the points given in the multiple choices.

If you look at Letter A, it shows the point (0,9). If you fill that in the formula. You solve the equation:

y - 9 = -3/4(x - 0)

y - 9 = -3/4x

Therefore your answer is letter A.

The number of leaves on a tree which is 2 yards tall and receives 9 hours of sunlight is 324 leaves.

z = k × y × x

Where,

If y = 10 yards, x = 3 hours, z = 540 leaves

z = k × y × x

540 = k × 10 × 3

540 = 30k

k = 540/30

k = 18

Then, find z when y = 2 yards and x = 9 hours

z = k × y × x

= 18 × 2 × 9

z = 324 leaves.

In conclusion, given the constant of proportionality, the number of leaves on the tree is 324 leaves.

The x-intercepts of the parabola are (x₁, y₁) = (6.67, 0) and (x₂, y₂) = (5.33, 0).

What is the equation of a parabola?

The general equation of a parabola is given by y = a(x – h)2 + k or x = a(y – k)2 +h. Here (h, k) denotes the vertex.

To write the equation of the given parabola in the desired form, we can complete the square.

The equation of a parabola with vertex at (h, k) and axis of symmetry x = h is given by:

y = a(x - h)^2 + k

where a is a nonzero constant.

In this case, the vertex is (6, -5) and the y-intercept is (0, 175), so the equation of the parabola is of the form:

y = a(x - 6)^2 - 5

Substituting the y-intercept, we have:

175 = a(0 - 6)^2 - 5

Solving for a, we find that a = 15/4.

Thus, the equation of the parabola is:

y = 15/4(x - 6)^2 - 5

To find the x-intercepts, we need to find the values of x such that y = 0. Substituting y = 0 into the equation of the parabola, we have:

0 = 15/4(x - 6)^2 - 5

Adding 5 to both sides, we have:

5 = 15/4(x - 6)^2

Dividing both sides by 15/4, we have:

4/15 = (x - 6)^2

Taking the square root of both sides, we have:

x - 6 = +/- 2/3

Thus, the x-intercepts are at x = 6 +/- 2/3.

Therefore, the x-intercepts of the parabola are (x₁, y₁) = (6 + 2/3, 0) and (x₂, y₂) = (6 - 2/3, 0).

Rounded to the nearest hundredth, the x-intercepts are (x₁, y₁) = (6.67, 0) and (x₂, y₂) = (5.33, 0).

The slope-intercept form of the equation of the line through the given point with the given slope is y=-4x+1.

The given coordinate point is (-1, 5) and slope=-4.

The slope intercept form of a straight line is one of the most common forms used to represent the equation of a line. The slope intercept formula can be used to find the equation of a line when given the slope of the straight line and the y-intercept.

The standard form of the slope intercept form is y=mx+c.

Substitute (x, y)=(-1, 5) and m=-4 in standard form of the slope intercept form, we get

5=-4×(-1)+c

⇒ c=5-4

⇒ c=1

Substitute m=-4 and c=1 in y=mx+c, we get

y=-4x+1

The null hypothesis (H0) would be that the population mean number of hours married men in your area spend on child care per week is equal to the reported mean of 6.0 hours per week.

The population mean number is equal to the reported mean according to null hypothesis. The alternative hypothesis (HA) would be that the population mean differs from the reported mean.

H0: μ = 6.0 hours/week

HA: μ ≠ 6.0 hours/week

b. To find the sample mean, we need to add up all of the values in the sample and divide by the number of values. The sample mean is 6.34 hours/week.

To calculate the test statistic, we can use the formula:

t = (x' - μ0) / (s / √n)

where x' is the sample mean, μ0 is the hypothesized mean (in this case, 6.0 hours/week), s is the sample standard deviation, and n is the sample size.

Plugging in the values, we get:

t = (6.34 - 6.0) / (3.23 / √40) = 0.34 / (0.53 / 6.32) = 0.34 / 0.08 = 4.25

The p-value is the probability of getting a result as extreme as the one we observed, given that the null hypothesis is true. In this case, we would need to use a t-distribution table or a computer program to find the p-value, since the sample size is small and the population standard deviation is unknown.

c. If we select a level of significance of 0.05, then we can use the p-value to make a decision about the null hypothesis. If the p-value is less than 0.05, we would reject the null hypothesis and conclude that the population mean differs from the reported mean. If the p-value is greater than 0.05, we do not have enough evidence to reject the null hypothesis and would conclude that the population mean is likely to be the same as the reported mean.

In this case, the p-value is greater than 0.207, so we do not have enough evidence to reject the null hypothesis. We would conclude that the population mean number of hours married men in your area spend on child care per week is likely to be the same as the reported mean of 6.0 hours per week.
