Answer: Well the image looks like a square so what does not appear to describe this quadrilateral is B; trapezoid. I just don’t know how to explain this but I think it is B. Sorry if I’m wrong but hope this helps.

Answer: Should be 130

Step-by-step explanation:

A is 80 180-80 is 100. Since it’s an isosceles you can divide by 2 and the two angles would be the same. 100/2 is 50 because two remote interior angles is equal to the exterior angle, 50+80 is 130, d is 130

Answer:

Angle D is 130 degrees

Step-by-step explanation:

180-80=50

Angles b and c are the same and will both be 50 degrees.

The angle of a straight line is 180 degrees.

Since angle c is 50 degrees, then the other angle (d) will have to be 130, so that together the total of the two is 180 degrees.

I hope this helps :)

Answer:

41 feet

Step-by-step explanation:

For a radius r, the circumference is [tex]2\pi r[/tex] and the diameter is [tex]2r[/tex], so to get diameter, we can just divide the circumference by pi and we get the answer. Using 3.14 for pi we get:

[tex]127.74 / 3.14 = 41[/tex]

Answer:

1256, 125.6 (this is wrong sorry i didn't know that it wasn't a full circle)

Step-by-step explanation:

A) The area that the sprinkler is spraying is in a circle with a radius of 20 ft. The formula to find the area of a circle is pi*r^2, so the area of this circle will be 400pi (substitute 20 for r). Pi in this problem is 3.14, so 400*3.14 is 1256 feet.

B) The perimeter of the spray is technically just the circumference of the circle. The circumference is 2r*pi, so we substitute 20 for r again and we get 40pi. Again, pi is 3.14 in this problem, so 40*3.14 is 125.6 feet.

Answer:

[tex]\displaystyle f(x)=-\frac{1}{24}\left(x-12\right)^2+6[/tex]

Where f(x) models the height, in inches, of the frog's leap after it had leapt x inches.

Step-by-step explanation:

We are given that a frog leaps two feet, with the highest point in the jump being six inches.

Assuming the frog starts at (0,0), we want to find a quadratic function in vertex form for the path of the jump.

First, we will convert the length of the jump to inches. Two feet is equivalent to 24 inches.

Next, since the frog started at (0, 0), in order to jump a length of 24 inches, it must have ended at (0, 24). These two points will also be our two roots: x = 0 and x = 24. We can use the factored form of a quadratic:

[tex]f(x)=a(x-p)(x-q)[/tex]

Where p and q are the roots.

Substitute in the roots:

[tex]f(x)=a(x-0)(x-24)=ax(x-24)[/tex]

Now, since the frog reached a maximum height of six inches, the y-coordinate of the function at its vertex point is 6.

Since a parabola is symmetrical along its axis of symmetry, the axis of symmetry is always halfway between the two roots.

Therefore, the x-coordinate of our vertex is:

[tex]\displaystyle x=\frac{24-0}{2}=12[/tex]

So, when x = 12, f(x) = 6. Substitute:

[tex]6=a(12)(12-24)[/tex]

Solve for a:

[tex]\displaystyle- 144a=6\Rightarrow a=-\frac{1}{24}[/tex]

Therefore, our function is:

[tex]\displaystyle f(x)=-\frac{1}{24}x(x-24)[/tex]

Now, we can place this into vertex form:

[tex]\displaystyle f(x)=a(x-h)^2+k[/tex]

Where a is the leading coefficient and (h, k) is the vertex.

Our leading coefficient is -1/24, and the vertex is (12, 6). Hence, our function is:

[tex]\displaystyle f(x)=-\frac{1}{24}\left(x-12\right)^2+6[/tex]

Where f(x) models the height, in inches, of the frog's leap after it had leapt x inches.

24-1 = 23

6-1/4 = 5 3/4

23/5 3/4 = 4

The constant is 4, so Vanessa is correct

The answer is:

D. Vanessa is correct because the quotient when dividing the values in the bottom row by the values in the top row is always 4.

Answer:

x = 1.5

Step-by-step explanation:

2x = 3

divide both sides by 2

x = 3/2

3 divided by 2 is 1.5 so

x = 1.5

Answer:

1.5

Step-by-step explanation:

[tex]2x = 3 \\ \frac{2x}{2} = \frac{3}{2 } \\ two \: cancle \: by \: two \: then \\ x = \frac{3}{2 } \\ x = 1.5[/tex]

Answer:

20

Step-by-step explanation:

Answer:

The answer is 875

Step-by-step explanation:

SO EASY- 2cm is equal to 10ft, so that means 5ft is equal to 1cm.

5*5=25

7*7=35

35*25=x=875

Answer: f(x) = 64 * (3/4)^x

Step-by-step explanation: f(x)=ab^x

When x=0 f(x) = 64

64 = ab^0

b^0 =1 so

64 =a

f(x)=64 b^x

When x=1 f(x) = 48

48 = 64 *b

Divide by 64

48/64 =b

6/8 =b

3/4 =b

f(x) = 64 * (3/4)^x

Answer:

Step-by-step explanation:

Answer A is not correct because if the kite moves both right and up, the x and y coordinates will change

Answer B is the same as answer A. The kite moved so the coordinates will change.

Answer D is also the same. If the kite moves both on the x and y axis, any angle and distance will change.

Answer C is correct. Since C does not rely on the coordinates, it will always be the same. The position of a shape does not change it´s perimeter.
