Answer:

the answer is 29.7

Step-by-step explanation:

inverse tangent of (4/7)

Answer: 9/1

Step-by-step explanation: Apologies for the mistake. Let's calculate the probability again.

To find the probability of rolling a sum of 9 on two number cubes, we need to determine the number of favorable outcomes and divide it by the total number of possible outcomes.

For a sum of 9, the following combinations are favorable:

(3, 6), (4, 5), (5, 4), (6, 3)

So, there are 4 favorable outcomes.

The total number of possible outcomes is still 6 × 6 = 36.

The probability of rolling a sum of 9 is:

Probability = Number of favorable outcomes / Total number of possible outcomes

Probability = 4 / 36

Simplifying the fraction, we get:

Probability = 1 / 9

Therefore, the probability of rolling a sum of 9 is 1/9, not 11/18 as previously stated.

15 minus 7 is 8

Answer:

1.) up

2.) (-2,-5)

3.) x = -2

4.) (-2,-5)

5.) y = -5

6.) -∞ < x < ∞

7.) -5 < y < ∞

8.) (0,0)

9.) (0,0) and (-4,0)

10.) two solutions

Step-by-step explanation:

1.) because the parabola opens upward and the vertex is down

2.) the lowest point of the parabola is (-2,-5)

3.) If a line was drawn through the point x = -2, the two halves of the parabola would look symmetrical ( the same on both sides).

4.) The minimum point on the graph is ( -2,-5), because that is the lowest point on this upward parabola, and we can not determine the maximum.

5.) The minimum value of y is y = -5, because that is the lowest value of y on this graph, and we can not determine the maximum.

6.) Because the arms of the parabola continue traveling through negative infinity and positive infinity on the x-axis, the domain is -∞ < x < ∞.

7.) The arms of the parabola go from y = -5 to infinity, so the range of the parabola is -5 < y < ∞.

8.) The parabola first crosses the y-axis at the point (0,0)

9.) The parabola first crosses the x-axis at the points (0,0) and (-4,0)

10,) The solution to the parabola is the variable x. The solutions (x intercepts) of the parabola are x = 0 and x = -4.

Answer:

The answer is D,

a(n) = 4/5 + 1/6(n- 1)

just took the test :)

Step-by-step explanation:

The explicit formula for the arithmetic sequence is D, a(n) = 4/5 + 1/6(n- 1)

An arithmetic sequence is sequence of integers with its adjacent terms differing with one common difference.

The explicit formula is given by:

[tex]T_n = a + (n-1)d[/tex]

Where a is the first term (4/5) and d is the common difference (the difference is any 2 terms).

Therefore, to find d:

29/30 - 4/5

29/30 - 24/30

d = 5/30

d = 1/6

Now putting them into the formula:

a(n) = 4/5 + 1/6(n- 1)

The last answer choice is right.

Answer:

2.2 : 1

Step-by-step explanation:

cube root 1331 : reciprocal of 0.2

give your answer in the form n:1

The cube root of 1331

(1331)^1/3 = 11

Reciprocal of 0.2 = 1 /0.2 = 5

Hence, the ratio Can be expressed as :

11 : 5

In the form n : 1

divide both sides by 5

Answer:

Step-by-step explanation:

1. x=-2, x=0

So, the equation in factored form would be x(x+2)=0.

2. x=0, x=4

So, the equation in factored form would be x(x-4)=0.

3. x=-2, x=0, x=4

So, the equation in factored form would be x(x+2)(x-4)=0.

Answer:

The line is a vertical line, which does not have a slope.

Step-by-step explanation:

Slope of a line:

Suppose we are given two points in the format (x,y) of a line. The slope is given by the change in y divided by the change in x.

(6,6) and (6, -7).

Change in y: -7 - 6 = -13

Change in x: 6 - 6 = 0

Slope is a division by 0, which means that the line is a vertical line, which does not have a slope.

Answer:

10

Step-by-step explanation:

Let's find f(2) first.

f(2) = 2 + 2 = 4

This means it would be f(g(4)).

Then let's find g(4).

g(4) = 4 + 4 = 8

Then, this means f(8).

f(8) = 8 + 2 = 10

Answer:

x int = (36,0)

y int = (0,2)

Step-by-step explanation:

Speed = distance / time

speed = 2/36 = 0.05555 Or 1/18 (as a fraction)

equation =      f(x) = 2 - x/18

graph

The equation that gives the distance f(x) left in miles as a function of the  number x of minutes she has been walking is [tex]f(x) = -\frac{x}{18} + 2[/tex]

The x-intercept of the graph is at (0, 2) which shows that the distance traveled at the beginning is 2 miles

The y-intercept of the graph is at (36, 0) which shows that no distance was covered when at when the time is 36 minutes

The general equation that represents the graph is expressed as:

[tex]f(x) = 2 - sx[/tex]

s is the speed of Kaitlyn

The formula for calculating the speed is expressed as;

[tex]speed = \frac{distance}{time}[/tex]

The function required will become;

[tex]f(x) = 2 - \frac{d}{t}x\\[/tex]

Given the following parameters

distance "d" = 2 miles

Time "t" = 36 minutes

Substitute the given parameters into the function as shown:

[tex]f(x) = 2 - \frac{2}{36}x\\f(x) = 2 - \frac{1}{18}x\\f(x) = -\frac{x}{18} + 2[/tex]

Hence the equation that gives the distance f(x) left in miles as a function of the  number x of minutes she has been walking is [tex]f(x) = -\frac{x}{18} + 2[/tex]

Get the y-intercept of the function:

If x = 0

[tex]f(x) = -\frac{0}{18} + 2\\f(x) = 2[/tex]

The y-intercept of the function is (0, 2)

Get the x-intercept of the function

[tex]0 = -\frac{x}{18} + 2\\-2 = -\frac{x}{18} \\x = 36[/tex]

Hence the x-intercept of the graph is expressed as (36, 0)

Answer:

[tex]C' = (2,8)[/tex]

[tex]A' = (4,4)[/tex]

[tex]T' = (10,10)[/tex]

Step-by-step explanation:

Given

[tex]k =2[/tex]

[tex]C =(1,4)[/tex]

[tex]A = (2,2)[/tex]

[tex]T =(5,5)[/tex]

Solving (a): The new points

To do this, we simply multiply the old points by the scale factor.

i.e.

[tex]New = Old * k[/tex]

So:

[tex]C' = (1,4) * 2 = (2,8)[/tex]

[tex]A' = (2,2) * 2 = (4,4)[/tex]

[tex]T' = (5,5) * 2 = (10,10)[/tex]
