What is the product? (38b* )-822

Mathematics
1 answer:
sergey [27]2 years ago
8 0

Answer:

\boxed{\sf D)\:-24a^3b^7}

Step-by-step explanation:

\sf (3a^2b^4)(-8ab^3)

We'll use rule of exponents to simplify expression.

\sf 3^1a^2b^4(-8)^1a^1b^3

Now, use the commutative property of multiplication.

\sf 3^1(-8)^1a^2a^2b^4b^4

In order to multiply power of the same base, we add their exponents.

\sf 3^2(-8)^1a^{2+1}b^{4+3}

→ Add exponents:

\sf 3^1(-8)^1a^3b^7

→ Multiply 3* -8

\sf -24a^3b^7

Joshua has a bag of marbles. In the bag are 5 white marbles, 3 blue marbles, and 7 green marbles. Peter randomly draws one marbl
Step2247 [10]

Answer:

1 / 5

Step-by-step explanation:

Given that:

Number of white marbles = 5

Number of blue marbles = 3

Number of green marbles = 7

Required is the approximate probability of drawing 2 green marbles, Note that drawing is done without replacement :

Probability = required outcome / Total possible outcomes

Total possible outcomes = sum of all marbles = (5 + 3 + 7) = 15 marbles

First draw:

P(Green) = 7 / 15

Second draw:

Required outcome = 7 - 1 = 6

Possible outcomes = 15 - 1 = 14

P(green) = 6 / 14

Probability of drawing out two green marbles :

(7/15 * 6/14) = 42 / 210 = 1 / 5

(01.05) Use the graph below to answer this question: graph of line going through negative 1, 4 and 2, 0 Find the average rate of
dsp73

1) Find the graph of a line passing through (-1, 4) and (2, 0).

The slope of two points can be determined by dividing the difference of y-values by the difference of x-values:

\frac{4-0}{-1-2} =\frac{4}{-3}

The slope of this equation is -4/3. Inputting this into the slope-intercept form of an equation, we get:

y=\frac{-4}{3} x+b

To find b, substitute x and y for one of the given coordinate pairs:

0 = (-4/3)(2) + b

0 = -8/3 + b

8/3 = b

Substitute the b value into the equation to finish the line:

y=\frac{-4}{3} x+\frac{8}{3}
