evaluate 5x^2-3x+2 for x=-3

Answers

Answer 1

Alright, so in PEMDAS, we first do exponents. 3^2=9, and we then have 5(9)-3(3)+2. After that, we have multiplication, where we have 5*9 =45 and 3*3=9, resulting in 45-9+2 and eventually 38

which system of linear inequalities has the point (2 ,1) in its solution set?

Answers

Answer:

its the last one number 4

Step-by-step explanation:

Final answer:

The system of linear inequalities that includes the point (2, 1) in its solution set is y ≥ 2x - 3 and y ≤ -2x + 5.

Explanation:

The system of linear inequalities that has the point (2, 1) in its solution set can be represented by the inequalities:

y ≥ 2x - 3y ≤ -2x + 5

To determine if the point (2, 1) satisfies these inequalities, we can substitute the x and y values into each inequality and check if the resulting statements are true. In this case, 1 is indeed greater than or equal to 2(2) - 3, and 1 is also less than or equal to -2(2) + 5, so the point (2, 1) is indeed in the solution set of this system of linear inequalities.

m₁ = (y₂-y₁)/(x₂-x₁) → m₁ =(4+2)/(5+5) = 6/10 →m₁ = 3/5

Now let's calculate the slope m₂ of ST:
m₂ = (-4-6)/(3+3) → m₂ = (-10)/6 → m₂ = -5/3

We can conclude that KM and ST are perpendicular since thee product of their respective slopes (m₁).(m₂) = - 1

The volume of a rectangular prism is:
V=(length x width x height)

In this figure, we have two rectangular prisms:

1)We calculate the volume of a left rectangular prism:
Data:
length=5 in
width=7 in
height=1 in

Volume₁=length x width x height =(5 in)(7 in)(1 in)=35 in³

2)1)We calculate the volume of a right rectangular prism:
Data:
length=9 in
width=7 in
height=4 in

Volume₂=length x width x height =(9 in)(7 in)(4 in)=252 in³

The volume of the figure below would be the sum of the both rectangular prisms:

Volume of the figure below=Volume₁+Volume₂=35 in³+252 in³=287 in³

Answer: the volume of the figure below would be 287 in³.

Answers

Answer:

The probability is 42%

Step-by-step explanation:

The probability that A and B, two independent events, happens is given by:

P=P(A)*P(B)

In this case, lets call A the event in which there are sunny weather tomorrow and B the event in which Tara goes to the beach. Taking into account that they are independent, that means that one event doesn't affect the other, the probability P that it will be sunny tomorrow and Tara will go to the beach is:

P=0.7*0.6=0.42

Multiplying P by 100, we get:

P=42%

So, the probability that it will be sunny tomorrow and Tara will go to the beach is 42%

y=13.5

If x = 2.7, 5x would = 5(2.7), because 5x can also be written as 5 times x. So if x = 2.7, it could be written as 5 times 2.7, hence, 5(2.7).

Indicate, in standard form, the equation or inequality that is shown by the graph. (0,4)(4,0)

Answers

(0,4)(4,0)

slope(m) = -1
use either of ur points....(0,4)...x = 0 and y = 4
sub and find b, the y int
4 = -1(0) + b
4 = b

equation is : y = -x + 4....in standard form, it is : x + y = 4

Answer:

standard form y = -x + b.

Step-by-step explanation:

Given : Graph and points (0,4)(4,0).

To find : Standard form of equation .

Solution : We have given that points (0,4)(4,0).

Let [tex]x_{1}[/tex] = 0 , [tex]x_{2}[/tex] = 4

[tex]y_{1}[/tex] =4 , [tex]y_{2}[/tex] = 0.

Slope = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex].

Plugging values

Slope = [tex]\frac{0 - 4}{4 - 0}[/tex].

Slope = -1 .

Standard form y = m x + b

y = -1 x + b.

Plug (0,4)

4 = -1 ( 0)+ b

4 = b .

Now , plugging values b= 4 , m = -1.

y = -x + b.

Therefore, standard form y = -x + b.

The answer would be A

A. The distance around a closed figure is the correct answer.

Explanation:

The definition of perimeter is : The summation of the outer sides of any closed figure. Like in a rectangle, its the sum of all the four sides. In a circle, its the measure of the outline of the circle also called the circumference.

Hence, the distance around a closed figure is called its perimeter.

Linda made $238 for 17 hours of work.
At the same rate, how many hours would she have to work to make $168?

Answers

238/17= 14 dollars per hr
168/14= 12 hrs
Final answer: 12 hrs

for every hour of work that Linda does, she earns $14.
Therefore if she works for 12 hours, she will earn $168.

you can solve this by doing 238 divided by 17 which equals 14
and then do 168 divided by 14 which is 12.

8 men and 6 women arrive separately in a random fashion to a meeting. What is the probability that the first 4 people to show up are men?

Answers

First, you add 8 and 6 which will be 14. Since it's asking for the first four, it would be 4 over 14.

You can reduce that which is always a good idea and it comes out to be 2 over 7. That because you would divide both the top and bottom (like usual) by 2 each.

If you would want it as a percent, you would turn it into a decimal first. The decimal would be .02857. That's of course if you divide 2 and 7 like normal.

From there you would move the decimal point over two places making it 28.57 percent.

One of two complementary angles is 8 degrees less than the other.
Which of the following systems of equations represents the word problem?

x + y = 90 and x - y = 8
x + y = 90 and 90 - x = 8
x + y = 90 and y = 8x

Answers

I think it is the middle one becuase complimentary angles add up to 90 degrees and if one is 8 less than the other it would be proved like that.

Answer: The correct option is

[tex](A)~~x+y=90,~~x-y=8.[/tex]

Step-by-step explanation: Given that one of the two complementary angles is 8 degrees less than the other.

We are to select the correct system of equations represents the given word problem.

Let x and y represents the two complementary angles where y is less than x.

Since one angle is 8 degrees less than the other and y is less than x, so we have

[tex]x-y=8.[/tex]

We know that the sum of two complementary angles is 90 degrees, so we get

[tex]x+y=90.[/tex]

Thus, the required system of equations representing the given word problem will be

[tex]x+y=90,\\\\x-y=8.[/tex]

Option (A) is CORRECT.

Solve the formula for the perimeter of a rectangle with width w and length l,for the length P=2w+2l solve for l

Answers

Answer:

[tex]l=\frac{P}{2}-w[/tex]

Step-by-step explanation:

we know that

The formula for the perimeter of a rectangle is equal to

[tex]P=2(w+l)[/tex]

where

l is the length

w is the width

Solve for l

That means ----> Isolate the variable l

Divide by 2 both sides

[tex]\frac{P}{2}=\frac{2(w+l)}{2}[/tex]

Simplify right side

[tex]\frac{P}{2}=w+l[/tex]

Subtract w both sides

[tex]\frac{P}{2}-w=w+l-w[/tex]

Simplify right side

[tex]\frac{P}{2}-w=l[/tex]

Rewrite

[tex]l=\frac{P}{2}-w[/tex]

Answer:Solve P = 2l + 2w for w.

The first step is to isolate the variable term, 2w.

The population of a particular country was 28 million in 1985; in 1990, it was 36 million. The exponential growth function A=28e^{kt} describes the population of this country t years after 1985. Use the fact that 5 years after 1985 the population increased by 8 million to find k to three decimal places.

Answers

A=28e^(kt)
A= 36 million
T=5 years (1990-1985)
36=28e^(5k)
Solve for k
First divide each side by 28 to get
36/28=e^(5k)
Take the log
Log (36/28)=5k×log (e)
5k=log (36/28)÷log (e)
K=[log (36/28)÷log (e)]÷5
K=0.05

The value of k is 0.05.

The exponential growth function is: A = 28e^kt

Where

A = future value of population

e = 2.718

k = growth rate

t = time

The exponential growth function can be written as:

36 = 28 x e^k 5

log(36/28) ÷ log(e) ÷ 5 = 0.05
