Which parent function is represented by the graph?

Answer:

i. x = -0.5 and 1.5; ii. x = 1.5

Step-by-step explanation:

For part i, we can take a look at the x-intercepts of the parabola. When a quadratic equation equals 0, this means that we are taking a look at its roots, or solutions.

The parabola intersects the x-axis at approximately -0.5 and 1.5. We can say this is an estimate to the solutions.

For part ii, the question is asking the x value that makes the function equal 2. We just look at the point where y = 2, which happens to be 1.5. So when x = 1.5, y = 2, which is what we want.

Answer:

Step-by-step explanation:

Your answer for  x = 25.35 is correct.

Since the night must be an integer, you need to take 26 as your final answer. b) for y = 1500, you solve for x to consider which one is better.

for plan A, y = 87 x + 2129, you have to pay $2129 before starting the trip, hence $1500 is NOT enough to pay.

for plan B, y = 171x and y = 1500, hence x = 8.77. So, with $1500 you can travel for 8 nights.

Answer:

Locate the ordered pair (0, –6). From that point on the graph, move up 2, right 1 to locate the next ordered pair on the line. Draw a line through the two points.

Step-by-step explanation:

The answer is the first one because the slope is technically [tex]\frac{2}{1}[/tex]

Up 2 over 1

Since the slope is positive, the graph goes to the right.

(0, -6) is the y intercept because it intersects the y - axis.

Then you draw those two points and connect them.

Answer:

The required probability is [tex]\frac{7}{9}[/tex].

Step-by-step explanation:

Set given is:

S = {1, 2, 3, 5, 15, 21, 29, 38, 500}

Total number of elements in set, [tex]n(S)[/tex] = 9

Let A be the event that the number is less than 29 ({1, 2, 3, 5, 15, 21}).

Number of items in the event A, [tex]n(A)[/tex] = 6

Probability of event A,

[tex]P(A) = \dfrac{n(A)}{n(S)}}=\dfrac{6}{9} \Rightarrow \dfrac{2}{3}[/tex]

Formula for probability of any event E:

[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text {Total number of cases}}[/tex]

Let B be the event that the number is odd (either of {1,3,5,15,21,29}).

Number of items in the event B, [tex]n(B)[/tex] = 6

Probability of event B,

[tex]P(B) = \dfrac{n(B)}{n(S)}}=\dfrac{6}{9} \Rightarrow \dfrac{2}{3}[/tex]

The event A and B have a few elements in common, i.e. numbers less than 29 which are odd as well.

The common elements are represented as:

[tex]A \cap B = \{1, 3, 5, 15, 21\}[/tex]

[tex]n(A\cap B) = 5[/tex]

[tex]P(A \cap B ) = \dfrac{n(A \cap B)}{n(s)}\\\Rightarrow P(A \cap B) = \dfrac{5}{9}[/tex]

To find probability of selecting a number which is either less than 29 (event A) or odd (event B),

We have to find [tex]P(A\ or \ B)[/tex] which is represented as [tex]P(A \cup B)[/tex] and the formula is:

[tex]P(A \cup B) = P(A) + P(B) - P(A \cap B)\\\Rightarrow \dfrac{2}{3} + \dfrac{2}{3} - \dfrac{5}{9}\\\Rightarrow \dfrac{12-5}{9}\\\Rightarrow \dfrac{7}{9}[/tex]

The required probability is [tex]\frac{7}{9}[/tex].

Answer:

The slope of the line through the points is -5/7

Step-by-step explanation:

Here, we want to calculate the value of the slope through the lines

Mathematically;

m = y2-y1/(x2-x1)

Where (x1,y1) = (-4,2)

and (x2,y2) = (3,-3)

Substituting these values, we have;

m = (-3-2)/(3-(-4)) = -5/7 = -5/7

The slope of the line through (-4, 2) and (3, -3) is; -5/7

According to the question;

The slope, m of the line is given mathematically as;

Therefore, in this case;

Slope, m = -5/7

Answer:

It is also a rhombus and a square!

Step-by-step explanation:

Answer:

18.2 cubic meters.

Step-by-step explanation:

From the measurements they give us, we assume that the shed has the shape of a rectangular prism, however, to calculate the amount of storage, we must calculate the volume.

The volume would be:

V = height * width * length

According to the statement height = 2, width = 2 and length = 3.25

V = 2 * 2 * 3.25

V = 13

That is, the volume of the shed is 13 cubic meters, but then they mention that the roof line to the peak is 0.8 meters high, which means that the volume can increase, the new volume would be changing the height = 2 + 0.8 = 2.8, the other values remain the same:

V = 2.8 * 2 * 3.25

V = 18.2

That is to say that when adding that part, the volume that is to say total amount of storage is 18.2 cubic meters.

Answer: 6.3 m

Step-by-step explanation:

"8% more" = 1.08 (which is 1+0.08). "10% less" = 0.90 (which is 1-0.10).

first = 5.25

her_best = 1.08*first

her_best = 0.90*winning

Substitute to determine the winning jump's length.

winning = 1.08*5.25/0.90 = 6.3

So, the winning jump was 6.3 meters.

What is the lowest common denominator?

✔ 6

Rewrite the difference as a sum of the fractions using the lowest common denominator.

✔ 5/6 + (–4/6)

What is the answer?

✔ 1/6

Step-by-step explanation:

Fractions can be combined by taking their LCMs

The numbers are given as:

[tex]\mathbf{\frac{2}{3}\ and\ \frac{5}{6}}[/tex]

The denominators are 3 and 6.

Factor both numbers;

[tex]\mathbf{3 = 1\times 3}[/tex]

[tex]\mathbf{6 = 1 \times 2 \times 3}[/tex]

So, the LCM is:

[tex]\mathbf{LCM = 1 \times 2 \times 3}[/tex]

[tex]\mathbf{LCM = 6}[/tex]

The lowest common denominator is 6

The expression is represented as:

[tex]\mathbf{ - \frac{2}{3}\ + \ \frac{5}{6}}[/tex]

Rewrite as:

[tex]\mathbf{ - \frac{2}{3}\ + \ \frac{5}{6} = -\frac{4}{6} + \frac{5}{6}}[/tex]

Hence, the new expression is [tex]\mathbf{-\frac{4}{6} + \frac{5}{6}}[/tex]

Answer:

Total interest in 1 year = $2,250

Step-by-step explanation:

Given:

Rate of simple interest = 3% = 0.03

Amount of investment = $25,000

Number of investment = 3

Find:

Total interest in 1 year .

Computation:

Simple interest = Amount of investment × Rate of simple interest

Simple interest = $25,000 × 0.03

Simple interest = $750

Total interest in 1 year = Simple interest × Number of investment

Total interest in 1 year = $750 × 3

Total interest in 1 year = $2,250

To the nearest tenth

80.4 =x

Answer:

80.4

Answer:[tex]36^{\circ}[/tex]

Step-by-step explanation:

A straight angle means that the angle has a measure of 180 degrees. Therefore:

[tex]CBD+ABC=180 \\\\(8x+16)+(6x-60)=180 \\\\14x-44=180\\\\14x=224\\\\x=16\\\\6x-60=6(16)-60=96-60=36[/tex]

Hope this helps!

Answer:

m∠ABC = 36 degrees

Step-by-step explanation:

8x + 16 + 6x - 60 = 180       Add both angles to equal 180

14x - 44 = 180

     + 44   + 44                     Add 44 to both sides

14x = 224                            Divide both sides by 14

x = 16

Plug this into the equation for angle ABC

6(16) - 60                             Multiply

96 - 60                                Subtract

m∠ABC = 36
