Answers

Answer 1

Answer:

Step-by-step explanation:

let the eq. of parabola be

y=ax²+bx+c

points (-1,0),(2,0),(3,4) and (0,-2) lie on it.

0=a-b+c

0=4a+2b+c

subtract

3a+3b=0

a=-b

4=9a+3b+c

-2=0+0+c

c=-2

a-b-2=0

-b-b-2=0

-2b-2=0

b+1=0

b=-1

a=-b=-(-1)=1

eq. of parabola is

y=x²-x-2

A school has a parking lot that is 150.23 feet by 135.12 feet. What is the perimeter of the parking lot?

Answers

Answer: 570.70 ft

Step-by-step explanation:

The perimeter is the distance around the entire parking lot.

The measurement of 150.23 ft by 135.12 ft is half of the distance of the lot because it represents just two sides yet there are 4 sides.

The other two sides have the same measurement as this is a rectangle.

The perimeter of the parking lot is:

= (150.23 * 2) + (135.12 * 2)

= 570.70 ft

An elephant at an animal sanctuary weighs 5.5 tons. He receives a daily nutritional supplement. The instructions say to give 1 fluid ounce of supplement for every 250 pounds of body weight. How many fluid ounces of supplement should the elephant receive? no options I need to type it in.

Answers

Answer:

44 fluid ounces.

Step-by-step explanation:

It's important to keep in mind that 1 ton is 2,000 pounds.

5 x 2,000 = 10,000 pounds.

You have to add 1,000 pounds because of the '.5' at the end of the 5. That leaves you with 11,000 pounds.

Now, you have to divide by 250 to find how many fluid ounces you need.

[tex]\frac{11,000}{250}[/tex] = 44.

You need 44 fluid ounces of supplement.

Answers

Answer:

A function is a relation that maps elements from one set (the domain, the set of the inputs) into elements from another set (the range, the set of the outputs). Such that each element of the domain can be mapped into only one element of the range.

Now let's analyze the given relations.

1)

Here we can see that the inputs are -3, -1, 1, and 2.

Then the domain (the set of the inputs) is:

D = {-3, -1, 1, 2}

And we can see that the outputs are 0, 2, and 5.

Then the range is:

R = {0, 2, 5}

We also can see that each input is being mapped into only one output, then this relation is a function.

2) In this case the inputs are -2, -3, and 5.

Then the domain is:

D = {-2, -3, 5}

And the outputs are 6, 7, 8

Then the range is:

R = {6, 7, 8}

And we can see that each input is mapped into only one output, then this relation is a function.

3) In this case we can see that the inputs are -4, -2, and 0

Then the domain is:

D = {-4, -2, 0}

And we can see that the outputs are -2, -1, 3, and 4.

Then the range is:

R = {-2, -1, 3, 4}

In this case, we can see that the input -4 is being mapped into two different outputs (3 and -1)

Then this relation is not a function.

: Brianna’s teacher asks her which of these three expressions are equivalent to each other. Expression A: 6x + 4 Expression B: 12x + 4 Expression C: 5x + x + 4 Briana says that all three expressions are equivalent because the value of each one is 4 when x = 0. Do you agree or disagree with Brianna?

Answers

Answer:

I disagree with Brianna.

Step-by-step explanation:

Expression A: 6x + 4

6(1) + 4

6 + 4

10

6(2) + 4

12 + 4

Expression B: 12x + 4

12(0) + 4

4

12(1) + 4

12 + 4

12(2) + 4

24 + 4

28

Expression C: 5x + x + 4

5(0) + (0) + 4

4

5(1) + (1) + 4

5 + 1 + 4

10

5(2) + (2) + 4

10 + 2 + 4

16

It is true that when you substitute the “x” in each expression with 0, you get 4. However, when you sustitute a different number, like 1 or 2, you get completely different answers. In order for these expressions to all be equal, they have to all get the same answer each time. Yet, notice how both expressions A and C got the same answer every time. This is because when you simplify expression C, you get 6x + 4 (when you add together 5x and x). Therefore, expressions A and C will always be equivalent.

Mr. Strand mowed 2 5 of his lawn. His son mowed 1 3 of it. Who mowed most of the lawn? How much of the lawn still needs to be mowed?

Answers

Answer:4/15 of the portion of land is left to be mowed.

Step-by-step explanation:

Portion of Lawn mowed by Mr Strand =2/5

Changing to decimal we have 0.4

Portion of Lawn mowed by his son=1/3

Changing to decimal, we have 0.333

From this , we can deduce that Mr Strand mowed most of the Lawn.

Now to find the portion of Lawn remaining to be mowed

Let total portion be =1whole

Such that portion left to be mowed

=1-(2/5+1/3)

1- 6 + 5/15

1-11/15

15/15 -11/15

4/15 of the portion of land is left to be mowed.

Find the slope-intercept form from the two points (0,8)
and (1, 10).

Answers

Answer:

y = 2x + 8

Step-by-step explanation:

We want an equation of the form y = mx + b (slope-intercept).

Look what happens to x as we go from (0, 8) to (1, 10):  x increases by 1.  This is the 'run' as we calculate the slope.

At the same time, y increases by 2 from 8 to 10.

The slope is defined as m = rise / run, and here is m = 2/1, or m = 2.

Write out y = mx + b and substitute 2 for m:  y = 2x + b.

To find the y-intercept, substitute 0 (from (0, 8) ) for x and 8 for y:

8 = 2(0) = b, so b = 8, and the desired equation is

y = 2x + 8

Show working to support your answer.​

Answers

Answer:

No

Step-by-step explanation:

Originally:

48:42

If some leave and some arrive = 10:11 given in question

So 48- 8 leave = 40 women

Therefore 42+2=44

Now the ratio is 40:44 (Actual amount of people)

When you simplify/ divide by 4 = 10:11

Total amount of people is 40+44= 84 which is less than 90

Step-by-step explanation: shooooooooo papi

Answer:

x = - 4

Step-by-step explanation:

The denominator of the rational expression cannot be zero as this would make it undefined.

Equating the denominator to zero and solving gives the value that x cannot be, that is

x + 4 = 0 ⇒ x = - 4

Thus x = - 4 is the excluded value
