Step-by-step explanation:

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: 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.

I think 480 + 960 + 672 = 2112

Answer:

a and c

Step-by-step explanation:

so we know that -2 is the greatest number in this inequality and with that, the 'equation' would look like this-

x<-2

now let us solve a-d-

0.25-2.50=-2.50

-4.25-(-2.75)=-1.5

-3.25-1.75=-5

-4.50-(-5.25)=0.75

**with negative numbers the 'smaller' the number is the greater it actually is ex. -2.50<-1** it works this way because the 'larger' the number gets the further away it becomes from 0 or whole numbers making it smaller than the negative numbers closer to zero such as -1**

hopefully, that makes sense

now let us see which equations fit our inequality- **we'll let the bolded ones mean that they fit the inequality**

a)-2.50<-2

b)-1.5<-2

c)-5<-2

d)0.75<-2

good luck :)

i hope this helps

brainliest would be highly appreciated

have a nice day!

Answer:

[tex]92\ yd^2[/tex]

Step-by-step explanation:

The given figure is a trapezoid, the formula for finding the area of a trapezoid is the following,

[tex]A=\frac{h(b_1+b_2)}{2}[/tex]

Where (h) is the height of the figure, and ([tex]b_1[/tex]) and ([tex]b_2[/tex]) are the bases. It is given that the height is (8) and ([tex]b_1[/tex]) is (8). The value of ([tex]b_2[/tex]) can be found by adding the value of ([tex]b_1[/tex]) to the "overhang" that ([tex]b_2[/tex]) has over ([tex]b_1[/tex]). Thus, ([tex]b_2[/tex]) is ([tex]8+7[/tex]) or rather ([tex]15[/tex]). Now substitute the values into the equation and solve for the area of the trapezoid,

[tex]A=\frac{8(8+15)}{2}[/tex]

[tex]=\frac{8(23)}{2}[/tex]

[tex]=4(23)[/tex]

[tex]=92[/tex]

Answer:

5(2c - 3) = 3(3c - 5)

=> 10c - 15 = 9c - 15c

=> 10c+15c = 9c + 15c

=> 25c = 24

=> c = 24/25

Answer:

c=0

Step-by-step explanation:

Remove the parentheses

10c - 15 = 9c - 15

10c = 9c

Move the variable to the left

10c-9c=0

Collect like terms

then solve it and you'll get c=0

Hope this helps.

Answer:

D. 126

Step-by-step explanation:

30 ÷ 5 = 6

5 * 6 = 30

6 * 6 = 36

10 * 6 = 60

60 + 30 + 36 = 126

Answer:

The median is 22

Answer: 22

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:

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:

6%

Step-by-step explanation:

first multiply $6000 by 7 years then divide 2520 by 42000 to get 0.06

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]

The probability is not 4/12 for the red marble, but 4/11

Step-by-step explanation:

Francisco calculated to probability of drawing a yellow marble correctly, but since he isn't replacing it, the amount of marbles in the bag is not 12, but 11. Since there are 4 red marbles, the probability is 4/11
