Answer:

B. y= - (0.25)^x+ 4

C. y= - (3)^x+4

Step-by-step explanation:

There is no impediment in an exponential function, so all of the have the domain (-infinity, infinity).

In an exponential function in the following format:

$-a^{x} + b$

The range is (-infinity, b).

So these following functions apply:

B. y= - (0.25)^x+ 4

C. y= - (3)^x+4

A and D have ranges from negative infinity to negative four.

Find the volume of a spere with radius of 7

choli [55]

Formula for volume of sphere V = 4/3 (Pi) r^3, where Pi ~ 3.14 and r is the radius = 7.

Therefore V = 4/3 * 3.14 * 7^3

= 4/3 * 3.14 * 343

= 4/3 * 1077.02

= 1,436.02667 cubic units

A card is randomly chosen from the cards in the image. Find the probability of choosing the cards with either Q or R on them.

Afina-wow [57]

The probability of choosing cards either Q or R when a card is drawn from a deck of 8 cards is 0.25.

Given that a card is randomly chosen from 8 cards shown in figure.

We have to calculate the probability of choosing either Q or R when a card is drawn from those 8 cards.

Probability means calculating the likeliness of happening an event among all the events possible. It lies between 0 and 1. It cannot be negative.

Number of cards=8

Number of repeated cards=0

Number of cards showing Q and R =1 each.

Probability of getting Q or R is P(X=Q)+P(X=R)

= 1/8+1/8

=2/8

=1/4

=0.25

Hence the probability of getting either P or Q when a card is drawn from 8 cards is 0.25.

Complete the tables of values.

zlopas [31]

<u>Answer with Step-by-step explanation:</u>

We are given two tables and we are to complete the missing values.

For table one, we are to substitute the given values of x in the term $4^{-x}$ :

when x = 0, $4^{-0} = 1$

when x = 2, $4^{-2} = \frac{1}{16}$

when x = 4, $4^{-4} = \frac{1}{256}$

For table two, we are to substitute the given values of x in the term $(\frac{2}{3} )^x$ :

when x = 0, $(\frac{2}{3} )^0 = 1$

when x = 2, $(\frac{2}{3} )^2 = \frac{4}{9}$

when x = 4, $(\frac{2}{3} )^4 = \frac{16}{81}$
