Answer:

a = 13, b = 28, c = 6, d = 22, e = 31

Step-by-step explanation:

Y = -2x^2

h = Xv = -B/2A = 0/-4 = 0.

k = -2*0^2 = 0.

V(0,0).

Use the following points for graphing:

Y = -2x^2.

Y = -2x^2 + 4.

h = Xv = -B/2A = 0/-4 = 0.

k = Yv = -2*0^2 + 4 = 4.

Step-by-step explanation:

First calculate the amount of notebooks and textbook

Cost of 2 notebooks = 2 *8.75

                                  = $ 17.5

Cost of 1 textbook = $ 74.95

Total cost = 17.5 + 74.95

                 = $ 92.45

Tax = 7% of total cost

      = 0.07 * 92.45

      = $ 6.47

Total cost = 92.45 +6.47

                 = $ 98.92

Jaleesa bought 2 notebooks for dollar 8. 75 and 1 textbook for dollar 74.95 . If the sales tax was 7[tex]{\%}[/tex],

what was the total cost of Jaleesa's purchases?

In this question we are provided with the cost of each textbook and notebook and it is given that Jaleesa bought 2 notebook and 1 textbook and the sale tax was.7% and we are asked to calculate the total cost of Jaleesa's purchases

First we will calculate the cost of two notebooks

Rate of 1 notebook = $8.75

Cost of 2 notebook = $(8.75 × 2) = $17.5

Now, we will calculate the total cost

Total cost of 2 notebook and 1 textbook = $(17.5 + 74.95) = $92.45

Sales tax was 7%

7% of $92.45

→ [tex]\dfrac{7}{100}[/tex] × 93.45

→ $6.47

Total cost = $(92.45 + 6.47) = $98.92.

The interest will the CD has earned more than the savings account after 1 year will be $49.90. Then the correct option is B.

The amount of something is expressed as if it is a part of the total which is a hundred. The ratio can be expressed as a fraction of 100. The word percent means per 100. It is represented by the symbol ‘%’.

Greg invests $2,680 in a CD paying 7.0% interest, and $3,060 in an online savings account paying 4.5% interest.

The amount of the interest on the CD will be

→ 2680 × 0.07 = $187.6

The amount of the interest by the online savings will be

→ 3060 × 0.045 = $137.7

Then the interest will the CD has earned more than the savings account after 1 year will be

→ $187.6 - $137.7 = $49.90

Find the stepsteps in the file.

Answer:

None.

Step-by-step explanation:

Let blue, green and purple be B, G, and P respectively.

Sample Space = 2+2+2 = 6

p(B) = p(G) = p(P) = 2/6 = 1/3

Probability that the two marbles Ummi selected are of the same color (note that the marbles were replaced after selection)

B = (1/3)•(1/3)

+

G = (1/3)•(1/3)

+

P = (1/3)•(1/3)

= 3•(1/9) = 1/3

.

The same thing goes for Julio.

They have the same chance/probability of picking two marbles of the same color.

Answer:

[tex] \sf \fbox{Option D have pair of triangles are similiar}[/tex]

Step-by-step explanation:

To prove triangles are pair we will use AAA property.

ln option A the given triangles 1 & 2 have a 36° Angle, but the remaining two angles of both the traingle are not mentioned, as long as we don't know the measure of other two angle of both the traingle we can't say that pair of triangles are similar.

Similarly In option B triangles 3 & 4 can't be pair of similar triangle

In option C triangle 5 & 6 don't have any common angle, hence it does not follows AAA property and the given pair of traingles are not similar.

In option D Two angles of each triangle are given so we can easily find the third angle of both the triangle. let's solve for the third angles of triangle 7 and 8.

in triangle 7,

All three angles of triangle 7 are 30, 60 & 90

Now in triangle 8,

All three angles of triangle 8 are 30, 60 & 90

Hence, both the triangles have same measure of all three angles we can say that triangle 7 & 8 are similar triangle.

Answer:

18.8

Step-by-step explanation:

Hey there!

In order to find the solution to this question, we need to find the circumference

To find the circumference, you need to take the diameter and multiply it by 3.14 which is pi

In this case, the diameter is 6

6 x 3.14 is 18.84 so this means that the circumference of the circle, or in this case, a cookie, is 18.84

Also, it says to round to the tenth so our final answer will be 18.8

So the answer to this question is 18.8

C=18.8

The Total Interest Combine will be interest from the compounded invesestment and that of the simple interest investement $13,974.54 plus $13,848.00 which is 27 822.54 US$

Given Data

Calculation For Compound Interest:

First, convert R as a percent to r as a decimal

r = R/100

r = 2.2/100

r = 0.022 rate per year,

Then solve the equation for A

A = P(1 + r/n)nt

A = 12,000.00(1 + 0.022/1)(1)(7)

A = 12,000.00(1 + 0.022)(7)

A = $13,974.54

Calculation For Simple Interest:

First, converting R percent to r a decimal

r = R/100 = 2.2%/100 = 0.022 per year.

Solving our equation:

A = 12000(1 + (0.022 × 7)) = 13848

A = $13,848.00

The states of matter are the distinct form in which matter exists. There are 5 states of matter Solids; Liquids; Gaseous; Plasma; and Bose-Einstein condensate.

Kim classify the water as gaseous because she boiled all the liquid away. Hence in their evaporated state, the water now assumes a gaseous form.

The masses of solids left in the there samples were 2.025 grams, 457 mg, and 589 mg.

Option A, y = -1/3x + 2

Step-by-step explanation:

Step 1:  Determine the equation

Looking at the graph we can see that the line will intersect the y-axis at around 2 units which eliminates options B and D.  Now, looking at the slope of the graph we see that it's going in a downward trend which means that the slope is negative.  That eliminates option C which leaves us with the only option of A.

Answer: Option A, y = -1/3x + 2
