Step-by-step explanation:

Given

h(x)= x^3 for 1≤x≤3

and

h(x)=5 x>3

Now finding h(1), i.e when x=1

x=1 lies in the range 1≤x≤3 hence putting value x=1 in x^3

h(1)= 1^3

     = 1

Now finding h(4), i.e when x=4

x=1 lies in the range x<3 hence putting value x=4 in h(x)=5

h(4)= 5 !

You will have to use trig to solve this:

The side you have is adjacent to the known angle

The side you are looking for is opposite the known angle

^^^This means you need to use tan:

tan(24) = [tex]\frac{x}{12}[/tex]

.445222 = [tex]\frac{x}{12}[/tex]

Volume of a rectangular prism is:

V = lwh

Given that l = 4½, w = 3½, and h = 6:

The volume is 94½ cm³.

The formula for the volume of a rectangular prism is:

V = length x width x height

OR

V = l x w x h

Answer:

C

Step-by-step explanation:

Find the height (h ) above eye level and add 5 to give height from floor level.

Since the triangle is right use the tangent ratio to find h

tan60° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{h}{5}[/tex]

Multiply both sides by 5

5 × tan60° = h, hence

h ≈8.66

The height is 8.66 + 5 = 13.66 ≈ 14 ft ( to nearest foot )

Answer:

D. The graph of h is the graph of g shifted 2 units to the left and 5 units down.

Step-by-step explanation:

Graph:  h(x) = g ( x + 2 ) - 5

x + 2 means the graph is shifted to left by 2 units.

-5 means to shift the graph down by -2 units

so, the graph of h is the graph of g shifted 2 units to the left and 5 units down.

Answer:

20

Step-by-step explanation:

Patrica got 80% correct.  She missed 4 problems, so that must have been the remaining 20% of the test.

Therefore:

4 = 20% x

Percent means out of 100, so:

4 = (20/100) x

4 = 1/5 x

x = 20

There were 20 problems on the test.

Answer: x < -1

Remember:

Answer: D, or x<-1

Step-by-step explanation:

The arrow on the number line indicates the direction in which the set of numbers represented is going. In this case, the arrow is pointing in the negative direction from -1; so we know that it will be either x < -1 or x ≤ -1

The circle represents whether the set of points is inclusive or exclusive. This is an exclusive case, which means that the point x = -1 is not included in the set of points.

That's how we know the inequality represented by the graph is x < -1

Answer:

y = [tex]\frac{2}{3}[/tex] x - 4

Step-by-step explanation:

Given y = f(x), then

y = f(x) + c represents a vertical translation

• If c > 0 then shift up by c units

• If c < 0 then shift down by c units

Here the translation is 4 units down ⇒ c = - 4, thus

y = [tex]\frac{2}{3}[/tex] x - 4

The equation of a line y = 2/3x moved 4 units down would be y = 2/3x - 4.

In the case of a vertical translation, the equation of a line y = mx + b is altered by adding or subtracting a constant value, which moves the line up or down on the coordinate plane. For example, with the given equation of a line, y = 2/3x, to translate it 4 units down, we subtract 4 from y. Therefore, the equation for the vertical translation would be y = 2/3x - 4.

The correct answer is B

Answer:

y=-4x-17

Step-by-step explanation:

You want to find the equation for a line that has a slope of -4 and a y-intercept of -17.

First of all, remember what the equation of a line is:

y = mx+b

Where:

m is the slope, and

b is the y-intercept

All you really have to do here is

replace m with -4, which is the slope you gave, and

replace b with -17, the y-intercept you gave,

in the equation y=mx+b.

The equation of the line that has a slope of -4 and a y-intercept of -17 is:

y=-4x-17.

Answer:

3) 3a - 2 + 3 = -2

   3a            = -2 + 2 - 3 = -3

   a              = -3/3 = -1

4) m/-6 - 18 - 4 = -16

   m/-6             = -16 + 18 + 4 = 6

   m                  = 6 · (-6) = -36

5) x/-2 - 4 + 22 = -28

   x/-2              = -28 + 4 - 22 = -46

   x                   = -46 · (-2) = 92

6) -13 = 5 + 20m - 2m

   -13 = 5 + 18m

   -18 = 18m

   m  = -18/18 = -1

7) -2(2p - 1) = -14

   -4p + 2   = -14

   -4p          = -14 - 2 = -16

   p              = -16/(-4) = 4

8) -1(8x + 20) = 12

   -8x - 20      = 12

   -8x              = 12 + 20 = 32

   x                  = 32/(-8) = -4

9) -49 = 7(2x + 3)

   -49 = 14x + 21

   -14x = 49 + 21 = 70

   x                     = 70/-14 = -5

10) 3(8h - 4) + 17 = -19

     24h - 12 + 17 = -19

     24h               = -19 + 12 - 17 = -24

     h                   = -24/24 = -1

ANSWER

(-1,2)

EXPLANATION

The given quadratic expression is:

[tex]f(x) = {x}^{2} + 2x + 3[/tex]

The coefficient of the quadratic term is already 1.

So we add and subtract the square of half the coefficient of x.

[tex]f(x) = {x}^{2} + 2x + 1 - 1+ 3[/tex]

We factor the first three terms to obtain

[tex]f(x) =(x + 1)^{2} + 2[/tex]

This is now in the form:

[tex]f(x) = a({x - h)}^{2} +k[/tex]

where (h,k) which is equal to (-1,2) is the vertex.

Answer:

Step-by-step explanation:

Both the events are equally likely so neither can be more likely.

The correct answer is: C Neither. Both events are equally likely.

Given that the probability of it snowing in Eastern Canada tomorrow is 0.4 and that of in Western Canada is 2/5,

We need to determine which of the given events is more likely,

To determine which event is more likely, we compare the probabilities provided for each event:

The probability of it snowing in Eastern Canada tomorrow is 0.4.

The probability of it snowing in Western Canada tomorrow is 2/5, which is equivalent to 0.4.

Since both probabilities are equal (0.4), we can conclude that both events, A (It snows in Eastern Canada tomorrow) and B (It snows in Western Canada tomorrow), are equally likely.

Therefore, the correct answer is: C Neither. Both events are equally likely.
