A square pyramid is shown. What is the surface area of the pyramid? Enter your answer in the box. 100 points

Answer:

The vertex would be (-3, -1)

Step-by-step explanation:

Since this is in vertex form already, a(x-h)^2+k  where h is the x value of the vetex, and k is y.

We would take the opposite of +3 and get -3, which gives us our x cordinate.

We don't change the k value, so it just stays -1, giving us our y value.

Therefore, the vertex is at (-3, -1)

Answer:

It's C

Step-by-step explanation:

-11-2d is greater of equal to 1

add 11 to both sides to get

-2d is greater of equal to 12

divide -2 to both sides which flips the greater than sign to less than

getting d is less than or equal to -6

Answer:

  f(x) = (x +3)(x +1)(x -2)

Step-by-step explanation:

When 'a' is a zero of a polynomial function in x, the binomial (x -a) is a factor of the polynomial.

__

The three zeros give rise to a polynomial with three factors:

  f(x) = (x -(-3)) · (x -(-1)) · (x -2)

  f(x) = (x +3)(x +1)(x -2) . . . . . your cubic function

__

This can be expanded using the distributive property.

  f(x) = (x² +4x +3)(x -2) = x³ +4x² +3x -2x² -8x -6

  f(x) = x³ +2x² -5x -6 . . . . . standard form

Answer:

95 assuming this is one number

Step-by-step explanation:

3/5 of 160 is 96

04 - 12 x 4 + 23 is 79

it is greater than 79 and less than 96

79 < x < 96

now find numbers between these 2 numbers that have digits adding to 14.

8+6 and 9+5

The problem included that the number must be odd and so the answer is 95

Answer:

55°

Step-by-step explanation:

Since ∠WXY has a square on ∠X, ∠WXY is a 90° angle. This means that the angles in between ∠WXY also sum up to 90°.

⇒ 35 + 4x + 7 = 90

⇒ 4x = 90 - 35 - 7

⇒ 4x = 48

⇒ x = 48/4 = 12

Substitute the value of x into the expression "4x + 7"

⇒ ∠ZXY = 4x + 7 = 4(12) + 7 = 48 + 7 = 55°

Answer:

We know that this is a 90° Angle.

We already have 35° so we subtract that from 90

90-35=55

So the value of ∠ZXY = 55°

Also, the value of X is equal to 12

Answer:

5000 square meters

Step-by-step explanation:

Create a rectangle and use any variable to lable it.

I used c and I know that the length is twice the width, so I added "c" for both widths and "2c" for both lengths.

Count the number of c's up and you will get 6.

Divide 300/6 to get the value for c.

You get 50 for c, so plug it in for the length 2(50) or 100, and plug it in for the width or 1(50).

Now that you have the length and width of the triangle, use length times width to find the area.

100x50=5000

Answer: 192 is the volume of the shape

Answer:

12%

Step-by-step explanation:

Simple interest formula:  A = P(1 + rt)

where:

Given:

Substitute given values into the formula and solve for r:

⇒ A = P(1 + rt)

⇒ 2232 = 1800(1 + r · 2)

⇒ 1.24 = 1 + r · 2

⇒ 0.24 = 2r

⇒ r = 0.12

Convert into percentage:

0.12 = 12/100 = 12%

Step-by-step explanation:

y = ax^n + bx^(n-1) ... + z

(0, 1) tells us that the constant term z = 1.

because x = 0 eliminates all other terms. and as the sum is 1, that means z = 1.

for the other pairs I strongly suspect

(-1, 3) : 2×(-1)² + 1 = 2×1 + 1 = 3

(-2, 9) : 2×(-2)² + 1 = 2×4 + 1 = 9

so, the fitting equation is

y = 2x² + 1

Answer:

Yes

Step-by-step explanation:
Use the Pythagorean theorem (a^2 + b^2 = c^2) to find out if the hypotenuse (20 cm) squared is equal to the sum of the other two sides when squared. This will determine if it is truly a right triangle.

Considering the table given, the constant of proportionality of the proportional relationship is of k = 0.8.

A proportional relationship is a function in which the output variable is given by the input variable multiplied by a constant of proportionality, that is:

y = kx

In which k is the constant of proportionality.

Researching the problem on the internet, the set of values is as follows: (4,5), (8,10), (12,15), ...

Hence the constant is given by k = 4/5 = 8/10 = 12/15 = ... = 0.8.

The constant of proportionality for a proportional table is calculated using:

y = kx

Make k the subject

k = y/x

So, we have:

Area of backyard

The Pythagorean theorem computed shows that the length of the guy wire, to the nearest foot, is 207 ft.

Here, we have two similar right triangles, ΔABE and ΔCDE.

CD = 11 ft

DE = 2 ft

BD = 35 ft

First, find AB:

AB/11 = (35 + 2)/2

AB/11 = 37/2

Cross multiply

AB = (37 × 11)/2

AB = 203.5 ft

Then, apply Pythagorean Theorem to find AE:

AE = √(AB² + BE²)

AE = √(203.5² + 37²)

AE = 207 ft

Therefore, the length of the guy wire is 207 ft.
