Mathematics
1 answer:
marishachu [46]3 years ago
8 0

Answer:

14

Step-by-step explanation:

According to order of operations (PEMDAS), you should multiply the numbers on the two sides of the addition sign first. So:

-4 x -5 = 20

and

2 x -3 = -6

Then you add those two numbers together:

-6 + 20 = -14

A scientist used a microscope to count the number of bacterial cells in a petri dish every hour. The graph shows the data collec
Alex777 [14]

The required relationship shown by the graph is the exponential relationship n =2^t . Option a is correct,

Given that,

A graph has been shown, showing the data,  what is the relationship between the number of bacteria with time is to be determined.

<h3>What is a graph?</h3>

The graph is a demonstration of curves that gives the relationship between the x and y-axis.

Since the recorded value from the graph is
At, t = 1 ; n = 2
At t = 2 ; n = 4
At t = 3 ; n = 8
At t = 4 ; n = 16
At t = 5 : n = 32
Here the above data show the exponential relation between n and t with the base value 2 i.e. n =2^t

Thus, the required relationship shown by the graph is the exponential relationship of n =2^t . Option a is correct,

The rectangular prism is made of 8 cubes and has and edge length of 1/2 in, what is the volume
sashaice [31]
Hello!

To find the volume of the prism you first have to find the volume of a cube

To do this you use the equation

V =  a^{3}

V is volume
a is side length

Put in the values you know

V =  \frac{1}{2}^{3}

Solve

V = 0.125

Now to find the volume of the prism you multiply the volume of one cube by the amount of cubes in the prism

0.125 * 8 = 1

The answer is 1 cubic inch

Hope this helps!

Which of the following shows one way to simplify 43Σn=1(3+9n)?
kramer

Based on the given summation notation, the expression that shows one way to simplify 43 Σ n=1 (3+9n) is (a) 43 Σ n=1 3 + 43 Σ n=1 9n

<h3>How to determine the summation expression?</h3>

The expression is given as:

43Σn=1(3+9n)

As a general rule, if a summation notation is represented using the following expression

Σ(a + bn)

The equivalent expression of the above summation notation is

Σa + bn

Where the variable a is a constant in the expression

This means that:

Σ(a + bn) = Σa + bn

Using the above equation as a guide, we have the following equivalent equation

43 Σ n=1 (3+9n) = 43 Σ n=1 3 + 43 Σ n=1 9n

Hence, based on the given summation notation; the expression that shows one way to simplify 43 Σ n=1 (3+9n) is (a) 43 Σ n=1 3 + 43 Σ n=1 9n
