Answer:

Vertical intercepts: (-2,pi/2) and (-10,pi/2)

Horizontal intercepts: (4,0) and (-4,0)

Step-by-step explanation:

I took the test and got it right.

The required horizontal intercepts are at approximately (41.81°, 0) and (138.19°, 0), and the vertical intercepts are at (0, 4) and (0, -10).

In the equation intercept is the value of the linear function where either of the variables is zero.

To find the horizontal intercept(s) of the limacon, we need to set r equal to zero and solve for theta.

r = 4 - 6sin(Ф)

0 = 4 - 6sin(Ф)

6sin(Ф) = 4

sin(Ф) = 4/6

sin(Ф) = 2/3

We can use an inverse sine function to find the value of theta:

Ф= sin^-1(2/3)

Ф≈ 41.81° or 138.19°

These are the values of theta where the limacon crosses the x-axis (horizontal intercepts).

To find the vertical intercept(s), we need to set theta equal to zero or pi and solve for r.

When Ф= 0:

r = 4 - 6sin(0)

r = 4

So the limacon intercepts the y-axis at (0, 4).

When Ф= pi:

r = 4 - 6sin(pi)

r = 10

So the limacon intercepts the y-axis at (0, -10).

Therefore, the horizontal intercepts are at approximately (41.81°, 0) and (138.19°, 0), and the vertical intercepts are at (0, 4) and (0, -10).

Answer:

B) 1153000

Step-by-step explanation:

Given

See attachment

Required

Number of households without computer in 2009

From the attachment, we have:

[tex]n=5170000[/tex] --- survey

[tex]p = 22.3\%[/tex] --- proportion without computer

So, the actual number is:

[tex]Number = p * n[/tex]

[tex]Number = 22.3\% * 5170000[/tex]

[tex]Number = 1152910[/tex]

[tex]Number \approx 1153000[/tex]

Answer:

range = 13

median = 23

mode = none

mean = 22

Step-by-step explanation:

Answer:

mean: 22

median: 23

mode: none

range: 13

Step-by-step explanation:

mean

the mean of a data set is the sum of all the terms divided by how many terms there is, so:

23 + 29 + 25 + 16 + 17 ÷ 5 = 22

median

the median of a data set is the middle number so we arrange in order:

16, 17,  23, 25, 29

23 is the middle, so that's the median

mode

the mode is the number that's repeated the most, there isn't any repeats, so there isn't a mode

range

The range is the lowest value (16) subtracted from the highest value (29)

29 - 16 - 13

to find the properties of the parabola.

y = -3(x+4)^2 - 8

Use the vertex form, y = a (x-h)^2 + k, to determine values of a,h and k

a = -2

h = -4

k = -8

Find the vertex (h,k)

(-4, -8)

As per the vertex form of a quadratic equation, the vertex of the given quadratic equation is (4, 8).

"A quadratic equation is an algebraic equation of the second degree in x. The quadratic equation in its standard form is ax² + bx + c = 0, where 'a' and 'b' are the coefficients, 'x' is the variable, and 'c' is the constant term. The first condition for an equation to be a quadratic equation is the coefficient of x² is a non-zero term(a ≠ 0)."

"The vertex form of a quadratic equation is:

y = a(x - h)² + k

Here, a, h, and k are real numbers, where a ≠ 0. x and y are variables.

Here, (h, k) is the vertex and (x, y) represents a point on the graph of the given equation."

Here, the given quadratic equation is:

y = f(x) = -2(x - 4)² + 8

By comparing it with the vertex form of a quadratic equation, we get:

h = 4, y = 8.

Therefore, the vertex(h, k) of the given quadratic equation is (4, 8).

Answer:

Juan has 32 dimes, 16 nickels and 8 quarters in his coin bank.

Step-by-step explanation:

Since in Juan's coin bank there are nickels (n), dimes (d), and quarters (q), and the number of quarters is one-quarter the number of dimes, and the number of nickels is twice the number of quarters, While the total value of the coins is $ 6.00, to find the number of each type of coin the following calculations must be performed:

Q = 1/4 D

N = 2Q = 1/2 D

D = D

20D + 10N + 5Q = X

20 x 0.10 + 10 x 0.05 + 5 x 0.25 = X

2 + 0.50 + 1.25 = X

3.75 = X

24D + 12N + 6Q = X

24 x 0.10 + 12 x 0.05 + 6 x 0.25 = X

2.40 + 0.60 + 1.50 = X

4.50 = X

32D + 16N + 8Q = X

32 x 0.10 + 16 x 0.05 + 8 x 0.25 = X

3.20 + 0.80 + 2 = X

6 = X

So, Juan has 32 dimes, 16 nickels and 8 quarters in his coin bank.

Explanation:

according to the coordinates the triangles is right at the pair (2, -3)

the area of the triangle = height × base × 1/2

the height is the line passing through the pairs (-1, 6) and (2, -3)

h² = (2-(-1))²+(-3-6)²

h² = 3² + (-9)²

h² = 9 + 81

h² = 90

h = √90

the base is the line passing through the pairs (5, -2) and (2, -3)

b² = (2-5)²+(-3-(-2))²

b² = 3² + (-3+2)²

b² = 9 + 1

b² = 10

b = √10

A = h×b×1/2

A = √90×√10×1/2

A = √900×1/2

A = 30×1/2

A = 15 u²

Answer: The answer to what is the measure of angle x is 48°.

Step-by-step explanation: It’s because this angle is complementary Two Angles are Complementary when they add up to 90 degrees (a Right Angle). They don't have to be next to each other, just so long as the total is 90 degrees. Example: 5° and 85° are complementary angles.

48°+42°=90° and this is a right scalene triangle.
