Answer:

She need to make 98 on the last assignment.

Step-by-step explanation:

Average = 92

x = mark on last assignment

(88 + 97 + 91 + 86 + x) / 5 = 92

To solve for x...multiply 5 on each side

(88 + 97 + 91 + 86 + x) / 5 * 5 = 92*5

This would get of / 5 so you don't need to divide by 5

362 + x = 460

Subtract 362 from each side

x = 98

Answer:

Step-by-step explanation:

They are showing you how to factor 12-9i+8i-6i².

Find the greatest common factor in each row and each column.

Blue:  GCF of 12 and -9i = 3

Orange: GCF of 8i and -6i² = 2i

Red: GCF of 12 an 8i = 4

Green: GCF of -9i and -6i² = 3i, but both terms are negative, so use -3i

Answer:

Step-by-step explanation:

Since, zeros of the relation are 5, 6 and y-intercept is (0, 30).

Therefore, equation of the quadratic relation will be in the form of,

y = a(x - 5)(x - 6)

For (0, 30),

30 = a(0 - 5)(0 - 6)

30 = 30a

a = 1

Therefore, equation will be,

y = (x - 5)(x - 6)

y = x² - 11x + 30

y = x²- 2(5.5)x + (5.5)² - (5.5)² + 30

y = (x - 5.5)²+ 30 - 30.25

y = (x - 5.5)² - 0.25 [Standard form}  

b). Vertex → (-4, -7) and passes through a point (-2, 1)

Vertex form or standard equation of the quadratic relation is,

y = a(x - h)² + k

Here, (h, k) is the vertex

Therefore, equation will be,

y = a(x + 4)² - 7

Since, (-2, 1) lies on this relation

1 = a(-2 + 4)² - 7

a(2)²- 7 = 1

4a = 8

a = 2

Equation will be,

y = 2(x + 4)²- 7

Step-by-step explanation:

Answer:

B.

Step-by-step explanaBtion:

The answer would be B

(7x+4)(7x-4)

you can tell because when you expand it e.g.

49x^2 +28x - 28x -16

simplify

49x^2 - 16

equals the expression

Answer:

The answer would be B: (7x+4)(7x-4)

Answer:

area of shaded region={6+7)×8-1/2×7×8=76 ft²

Answer:

The area of the purple is 76 feet.

Step-by-step explanation:

8 * 6 = 48

the full rectangle is 48ft in area

7 * 8 = 56

56 / 2 = 28

48 + 28 = 76ft

plz mark as brainliest if correct!

Step-by-step explanation:

Answer:

10 minutes

Step-by-step explanation:

This is somewhat of a trick question and also incomplete.

Assuming he walks his dog 1/6th of an hour each week, he walks his dog 10 minutes per week.

If this is incorrect please tell me the complete question

Step-by-step explanation:

5/8-7/8=2/8 so that is the height

the width is 1/2

and the length is 3/8

you have too multiply 1/2 and 3/8 which is 3/16.

hope this is correct and helps u out

Answer:

2.4

Step-by-step explanation:

Step 1: Calculate

Calculate the square root of 6 to be:

√6 = 2.44948974278318

Step 2: Reduce

Reduce the tail of the answer above to two numbers after the decimal point:

2.44

Step 3: Round

Round 2.44 so you only have one digit after the decimal point to get the answer:

2.4

Answer:

Step-by-step explanation:

Answer:

(0, -10), (2, 0), (-2, -50)

Step-by-step explanation:

Plug in numbers for the x and solve for it

I will start with 0

y = 5(0 - 1)^2 - 5

y = 5(-1) - 5

y = -5 - 5

y = -10

2

y = 5(2 - 1)^2 - 5

y = 5(1) - 5

y = 5 - 5

y = 0

-2

y = 5(-2 - 1)^2 - 5

y = 5(-9) -5

y = -45 - 5

y = -50

You just keep plugging in numbers until your graph finds its shape. Of course, you can chart the numbers I have already found.

Answer:

Step-by-step explanation:

they want the values of y and x.

DA=BC

DC=AB

so we can tell that given that E is an intersection:

DE=BE

CE=AE

Answer:

x = 0, y = -4

Now plug it in:

y = mx + b

-4 = b

So the y intercept is -4

You can also graph the equation.

Answer:

about 52.1 in.

Step-by-step explanation:

PM=PE=5 inches, PR=4 inches, and OP=19 inches.

Since the figure is a kite, the diagonals ME and OR are perpendicular and form right triangles with their hypotenuses forming the sides of the kite, OM, MR, RE, and EO.

The figure shows the same kite O M R E as in the beginning of the task. Diagonal O R is perpendicular to diagonal M E.

Use the Pythagorean Theorem to calculate the length of OM.

OM=OP2+PM2−−−−−−−−−−√

Substitute 19 for OP and 5 for PM.

OM=192+52−−−−−−−√

=361+25−−−−−−−√

=386−−−√

Therefore, OM=386−−−√ in.

By the definition of a kite, OM≅EO. So, EO is also equal to 386−−−√ inches.

Use the Pythagorean Theorem to calculate the length of MR.

MR=PM2+PR2−−−−−−−−−−√

Substitute 5 for PM and 4 for PR.

MR=52+42−−−−−−√

=25+16−−−−−−√

=41−−√

Therefore, MR=41−−√ in.

By the definition of a kite, MR≅RE. So, RE is also equal to 41−−√ inches.

The figure shows the same kite O M R E as in the beginning of the task. Sides O M and E O are square root of 386 inches long. Sides M R and R E are square root of 41 inches long.

The perimeter of the kite is the sum of the four sides.

Perimeter of OMRE=OM+MR+RE+EO

=386−−−√+41−−√+41−−√+386−−−√

=2386−−−√+241−−√

Use a calculator to approximate.

Perimeter of OMRE≈52.1 in.

So, the perimeter of OMRE is about 52.1 inches.

Therefore, about 52.1 inches of binding are needed to cover the edges of the kite.
