Answer:

y = 5

Step-by-step explanation:

A line with a slope of 0 is a horizontal line parallel to the x- axis with equation

y = c ( c is the value of the y- coordinates the line passes through )

the line passes through (- 4, 5 ) with y- coordinate 5 , then

y = 5 ← equation of line

A difference quotient that best approximates the instantaneous rate of change of g at x=2.5 is; -3

We can define the average rate of change of a function g(x) in an interval [a, b] as:

r = [g(b) - g(a)]/(b - a)

Particularly, if we want to find an approximation of the rate of change for a particular value x', we can choose:

a < x' < b

Such that a and b are really close to x'.

Then if we want to find the instantaneous rate of change of g at x = 2.5, we need to find values of a and b really close to 2.5.

Looking at the graph, we can choose:

a = 2

b = 3

(are the two closer ones to 2.5)

Then the rate of change can be written as:

f'(x) = g(3) - g(2)]/(3 - 2)

f'(x) = (1 - 4)/1

f'(x) = -3

Thus, we can conclude that a good approximation of the instantaneous rate of change is -3.

Answer: It is m<U = 60 and m<V = 120 (x = 20)

Step-by-step explanation:

1. We know that these 2 angles are supplementary, which means both adds up to 180 degrees.

2. So first, we do this:
             3x + 2(m<U) = 180
          2a. We do this to find m<U

3. We can also notice that 3x is m<U, so substituting m<U with 3x makes sense. 3x + 2(3x) = 180

4. We then simplify:
3x + 6x = 180
9x = 180

5. We will then divide:
x = 20

6. With the new found info, we substitute x with 20:
m<U = 3(20)
m<V = 2(3(20))

7. Doing the math, it becomes:
m<U = 60
m<V = 120

Step-by-step explanation:

(4h⁴)⁴ / (4h^-8)

remember, multiplying exponents means adding them. exponents of exponents means multiplying them.

and dividing exponents means subtracting them.

also, n^-a = 1/(n^a).

let's look at the numerator (top part) first :

(4h⁴)⁴ = 4^1×4 × h^4×4 = 4⁴×h¹⁶

now, for the denominator, the exponent -8 applies only to h. not to 4.

so,

1/(4h^-8) = h⁸/4

and so, the whole expression is then simplified

4⁴×h¹⁶ × h⁸/4 = 4³ × h²⁴

Solution:

[tex]y = \frac{1}{2}[/tex]

Process of Solution:

1. Switch sides.

[tex]y-1=-\frac{1}{2}[/tex]

2. Add 1 to both sides.

The area of triangle ABC when Angle B=120°, AB= 6, BC = 10 is 25.980 square unit.

As per the question statement, we are supposed to find out the area of triangle ABC in which angle B=120°, AB= 6, BC = 10.

Lets find out AC for which we should know about Cosine formula

i.e., [tex]AC^{2} =AB^{2} +BC^{2} -2(AB)(BC)cos(B)\\AC^{2} =6^{2} +10^{2} -2*6*10cos120\\AC^{2}= 36+100-120*(-0.5)\\AC^{2}=196\\AC=\sqrt{196} =14[/tex]

Hence We have measures of all three sides of the triangle ABC.

Now we use the Heron's formula for calculating the area of triangle ABC.

We need semi perimeter i.e., [tex]s=\frac{AB+BC+AC}{2}[/tex]

[tex]s=\frac{30}{2} =15[/tex]

Now Area is given by,

[tex]area=\sqrt{s(s-AB)(s-BC)(s-AC)} \\area=\sqrt{15(15-6)(15-10)(15-14)} \\area=\sqrt{15*9*5*1} \\area=\sqrt{675} \\area = 25.980 unit^{2}[/tex]

Answer:Answer:

The measurement of the angle is 60

Step-by-step explanation:

The two blue lines are straight and parallel lines. The sum of the angles on a straight line is 180 degrees. Angle 5 and angle 6 are on a straight line. Therefore

Angle 5 + angle 6 = 180

If angle 5 is 120 degrees, then

Angle 6 = 180 - 120 = 60 degrees.

The probability that the bolt will be inserted in 19 minutes or less is 0.8413.

It should be noted that the probability will be illustrated as:

P(X < x) = P[z < (x - u/sd)]

where

x = number

u = mean

SD = standard deviation

Therefore given the numbers, this will be:

P(x < 19) = P(z < (19 - 15)/4)

= P(z < 4/4) = P(z < 1)

= 0.8413

There is no relationship between the number of movies and the number of sleep hours.

It is always a thing of importance to show data by the use of a scatter plot. The scatter plot must always have two axes. The vertical (y axis ) and the horizontal (x axis). It is always common to plot the independent variable on the x axis and the dependent variable on the y axis.

The scatter plot thus represented shows how one variable is related to another. In this case, we are trying to obtain how the number of sleep  hours tend to be related with the number of movies and this has been shown on the scatter plot that is shown in the question above.

It is clear from the statements in the question that the line of best fit would show that as the number of movies remained constant, the number of sleep hours decreased. This now implies that there is no relationship between the number of movies and the number of sleep hours.
