1: domain: 1, 3, 5, -2, -3

Range: 1, 3, 5, 1, -3

2: Domain: 2, 1, -1, -3, -3

Range: 3, -4, -2, 1, 3

Step-by-step explanation:

the domain is the x intercepts, so if the coord is (5, 7) the domain would be 5

The range is the y intercept, so if the coord would also be (5. 7) the range would be 7

) A different rectangle has area 12a² and perimeter 14a
What are the dimensions of this rectangle?
Dimensions:
. by

Answers

Answer:

l = 4a and b = 3a

Step-by-step explanation:

Given that,

The area of the rectangle, A = 12a²

Perimeter, P = 14a

The area and perimeter of a rectangle are given by :

A = lb

12a² = lb ....(1)

P = 2(l+b)

14a = 2(l+b) ....(2)

We need to solve equations (1) and (2). After solving we find that.

l = 4a and b = 3a

Hence, the dimensions of this rectangle are 4a and 3a.

7) Rob and Amy are selling cheesecakes for a school fundraiser. Customers can buy New York
style cheesecakes and chocolate marble cheesecakes. Rob sold 11 New York style cheesecakes
and 7 chocolate marble cheesecakes for a total of $266. Amy sold 4 New York style cheesecakes
and 14 chocolate marble cheesecakes for a total of $280. What is the cost each of one New York
style cheesecake and one chocolate marble cheesecake?

Answers

9514 1404 393

Answer:

New York style: $14Chocolate Marble: $16

Step-by-step explanation:

We can let n and c represent the costs of the New York style and the chocolate marble cheesecakes, respectively. Then the two sales are ...

11n +7c = 266 . . . . . . . Rob's sale

4n +14c = 280 . . . . . . Amy's sale

The ratio of coefficients of c is a "nice" number (2), so we can eliminate the c variable easily to solve this. Dividing the second equation by 2 and subtracting it from the first gives ...

(11n +7c) -(1/2)(4n +14c) = (266) -(1/2)(280)

9n = 126 . . . . . . simplify

n = 14 . . . . . . . . divide by 9

Filling this into the first equation, we have ...

11(14) +7c = 266

7c = 112 . . . . . . . . subtract 154

c = 16 . . . . . . . divide by 7

One New York style cheesecake costs $14; one chocolate marble cheesecake costs $16.

Find the perimeter of the semicircular region. Round your answer to the nearest hundredth.

Answers

9514 1404 393

Answer:

30.85 in

Step-by-step explanation:

The circumference of a circle with a 6" radius is ...

C = 2πr

C = 2π(6 in)

Then the curved portion of a semicircle with that radius will have the length ...

1/2C = 1/2(2π)(6 in) = 6π in . . . . curved length

The straight portion of the boundary of this figure is simply twice the radius, so is ...

2×6 in = 12 in . . . . straight length

The perimeter is the sum of the curved and straight lengths:

P = (6π +12) in ≈ 30.8496 in ≈ 30.85 in . . . . figure perimeter

10.) Find values of x and y for which ABCD must
be a parallelogram.
A x=2 y=4
B x=2 y=6
C x=2 y=16
D x=6 y=2

Answers

Answer:

B x=2 y=6

Step-by-step explanation:

For ABCD to be parallelogram, following conditions should be satisfied:

2x - 0 = x + 2 & 4y - 8 = y + 10

2x - 0 = x + 2

2x - x = 2

x = 2

4y - 8 = y + 10

4y - y = 10 + 8

3y = 18

y = 18/3

y = 6

Answers

The features that is present in this polar graph is that A. Symmetry about the polar axis θ = 0.

What is true of the polar graph?

The polar graph can be said to have a symmetry about the polar axis which means that theta or θ is equal to 0.

This is because the graph is symmetric about the x-axis. This means that all the lines of symmetry can be seen intersecting the graph at x = 0. This proves that there is indeed symmetry in the polar graph.

In conclusion, option A, θ = 0 is correct.

Answer:

b = 40km is the answer.

Step-by-step explanation:

a = 9km

b = ?

c = 41km

By using the Pythagoras theorem,

a² + b² = c²

9² + b² = 41²

81 + b² = 1681

b² = 1681 - 81

b² = 1600

b = 40km

∴ b = 40km is the length of the missing leg.

what is the slope for this graph ?

Answers

Answer:

um 6/1?

Step-by-step explanation:

Answer:

Step-by-step explanation:

The slope of a line is the change in the line. It is often referred to as the ([tex]\frac{rise}{run}[/tex]), the slope of the line can be found using the following formula,

[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

The graph of the given line gives one the points (7, 2), (9, 6). Substitute these points into the given formula and solve for the slope,

[tex]\frac{6 - 2}{9 - 7}[/tex]

If the outside diameter of a pipe is 1.25 ft and the inside diameter is 0.975 ft how thick is the pipe

Answers

Answer:

0.275

Step-by-step explanation:

1.25-0.975=0.275

See below
Answer: .1375

See explanation:

1.25-0.975=.275

Now since this gives you the difference between the outside diameter and the inside diameter it actual gives you 2 times the wall thickness. So we need to divide that by 2.

.275/2=.1375

So the wall thickness of the pipe is .1375

the nutrition information on the cereal box says that a 1/2-cup serving provides 210 calories and 6 grams of dietary fiber. at that rate, find how many calories and grams of fiber are in a 1/3-cup serving

Answers

Answer:

140 Calories and 4 grams of dietary fiber per 1/3-cup serving.

Step-by-step explanation:

hi you can find this by first doubling the amounts for a 1/2 cup serving

so then it is equal to a full cup serving.

and then divide those by three,

that way it will be equal to 1/3 cup serving.

210*2= 420 (lol)

6*2= 12

now divide these numbers by 3

420/ 3 = 140

12/3= 4

so your answers are

140 Calories and 4 grams of dietary fiber per 1/3-cup serving.
