skad [1K]

Answer:

D.) 7 and -4

Step-by-step explanation:

Coefficients are numbers placed directly before a variable.

(7) is a coefficient because it is placed before x².

(-4) is a coefficient because it is placed before x. The negative is included.

(6) is not a coefficient because it is not altering any variable through multiplication/division.

konstantin123 [22]

Answer:

128500

Step-by-step explanation:

This is an arithmetic sequence with a common difference of 3500

The formula for an arithmetic sequence is

an = a1+d(n-1) where a1 is the first term and d is the common difference

an = 48000+ 3500(n-1)

We want n = 24

a24 = 48000+3500(24-1)

= 48000+3500(23)

=48000+80500

=128500

HELP ME PLS ITS BEEN AN HOUR LUV U GUYS <33

Setler [38]

Answer:

19.6 cubic centimeters

Step-by-step explanation:

The ratio of two similar 3D figures' volumes is equivalent to the ratio of their corresponding lengths (whether it's width, height, length, radius, etc) cubed.

Here, we know the cones are similar, and we know the smaller radius is 2 and the larger radius is 3. Then the ratio of the volume of the smaller one to the volume of the larger one is $(2/3)^3=8/27$ .

We also know the actual volume of the larger cone is 66. So, if x is the volume of the smaller cone, we have the proportion:

x / 66 = 8 / 27

Cross-multiply:

27x = 66 * 8 = 528

Divide by 27:

x = 528/27 ≈ 19.6

The answer is thus 19.6 cubic centimeters.
