Answer 1

Answer:

f(-3)= 15

Step-by-step explanation:

f(-3) means x is equal to -3

-3 squared - 2(-3)

-3*-3 -2(-3)

*Negative multiplied by a negative equals a positive

9+6= 15

f(-3)= 15

Hope this helps!

Answer 2

Answer:

put (-3) in place of x then it will be 9-6 then f(-3)=3

A rental car company charges $68.64 per day to rent a car and $0.12 for every mile driven Jackson wants to rent a car knowing that he plans to drive 500 miles he has at most $210 to spend what is the maximum amount of number of days that Jackson can rent a car while staying with his budget

Answers

Answer:

maximum amount of number of days that Jackson can rent a car while staying with his budget is 2 days

Step-by-step explanation:

first of all find the amount of money he will spend for 500 miles

in this case we multiply 0.12 by 500

=> 0.12 × 500

=> 60

subtract 60 from the money budgeted which is $210

=> $210 - 60

=> 150

divide 150 by the company charges per day which is dollars 68.64

=> 150 ÷ 68.64

divide 150 by 68.64

=> 2.185314685314685

approximately

=> 2 days

Answer:

Step-by-step explanation:

Let's say the number of days that Jackson can rent the car is x. By the question to know 6

what is 0.75x – 100 ≤ 80

Answers

Answer: X is less than or equal to 240

The solution to the inequality 0.75x - 100 ≤ 80 is x ≤ 240.

Given is an inequality what is 0.75x – 100 ≤ 80, we need to solve it,

To solve the inequality 0.75x - 100 ≤ 80, we can follow these steps:

1. First, let's isolate the variable x by adding 100 to both sides of the inequality:

0.75x - 100 + 100 ≤ 80 + 100

0.75x ≤ 180

2. Next, we can divide both sides of the inequality by 0.75 to solve for x:

(0.75x) / 0.75 ≤ 180 / 0.75

x ≤ 240

Therefore, any value of x that is less than or equal to 240 will satisfy the inequality.

Therefore, the solution to the inequality 0.75x - 100 ≤ 80 is x ≤ 240.

5) bottom bigger square with dimensions 5 by 12
A = base * height
A = 60
Now for the top part, we know that the bottom square uses 5 cm of that 10 cm long vertical
So 10-5 = 5 for height and the base is given as 4cm
A = 4*5 = 20
So 20 + 60 = 80 square cm
6) bottom bigger is 5 by 3
A= 15
The top smaller is 1 by 2
A= 2
So area is 15+2 or 17 square cm
7) again bottom big is 11 by 5
A = 5*11 = 55
The smaller left top is 7-5 or 2 height
So dimensions are 1 by 2
A = 1*2 = 2
55 + 2 = 57 square cm

pls help i don’t know how to do this

Answers

Step-by-step explanation:

to do what ?

the calculation of the 2 solutions for the quadratic equation is already done here.

so, what else do you need ? an explanation ?

in general, a quadratic equation looks like

ax² + bx + c = 0

and the formula for the solutions is

x = (-b ± sqrt(b² - 4ac))/(2a)

remember, a linear equation (x¹) has one zero solution.

a quadratic equation (x²) has 2 zero solutions.

a cubic equation (x³) has 3 zero solutions.

and so forth.

the 2 solutions here are created by the "±" operation. one solution is using the "+". and the other the "-". that is all.

so, what happened here was simply putting the values of the given equation into the solution formula and doing the calculations.

and the final line is saying that the solutions are the set of the 2 numbers represented by the "±" expression.

to finish this up for better clarity :

the first solution is

x = (-17 + sqrt(217))/4 = -0.567270034...

the second solution is

x = (-17 - sqrt(217))/4 = -7.932729966...

is there anything still unclear ? please let me know.

Answers

The modifications did Kepler make to Copernicus’s model are planetary orbits are elliptical (A) and Earth’s rotation causes the rising and setting of the sun (E).

What are the laws of Kepler?

There are three laws, made by the Kepler, to explain the motion of the planet around the sun.

First Law-According to this law, all the planets moves in the elliptical orbits. The center of this orbital path is the Sun. Thus Planetary orbits are elliptical. Second Law-The planet moves in elliptical orbit. The line of planet and sun sweeps out equal mass in equal time.Third Law-The square of the period of a planet to complete one path of electrical orbit is directly proportional to the cubes of semi-major axis of their orbit.

Earth’s rotation causes the rising and setting of the sun because of the earth's rotation on its axis.

Hence, the modifications did Kepler make to Copernicus’s model are planetary orbits are elliptical (A) and Earth’s rotation causes the rising and setting of the sun (E).

if you are counting up or down you go to (input the value) the y. if you want to find J for example, (the y coordinate) you go to the black dot and you count starting from 0. usually it will have the points -5 -4 -3 -2 -1 0 1 2 3 4 5 but in your problem it does not have so you just have to count carefully.

first set the inside values equal to 90 degrees (6m + 6) + 36 = 90.

then easily work it out.

subtract 36 from each side

(6m + 6) + 36 = 90

Answers

Answer:

A

Step-by-step explanation:

[tex]\sqrt{50}[/tex] is not a perfect square. This means that you can rule out answers B and D, because it won't be 'exactly' anything.

Let's think about the other answer choices. C says that the answer of \sqrt{50} will be between 24 and 25. This is easily checkable by doing [tex]24^{2}[/tex], which equals 576. This easily eliminates option C.

Now, if the other answer choices weren't so obviously incorrect, let's see how you would solve this. What's the closest perfect square root under 50?

[tex]\sqrt{49}[/tex], which equals 7.

What's the closest perfect square root above 50?

[tex]\sqrt{64}[/tex], which equals 8.

This puts [tex]\sqrt{50}[/tex] between 7 and 8.

Answer:

Option A

Step-by-step explanation:

Here we can find out the correct option by eliminating the wrong options . We know that √50 is not a perfect square.

This eliminates option d as it says that its value is exactly 7 .

[tex]\implies \red{\text{ Option D is wrong }}[/tex]

Now look at Option C , it says that it lies between 24 and 25 . This is impossible since , 24² = 576 and 25² = 625 .

[tex]\implies \red{\text{ Option C is wrong }}[/tex]

Again the option b is similar to option d , as it says its exact value is 25 which is not possible. Hence this option is also wrong .

[tex]\implies \red{\text{ Option B is wrong }}[/tex]

Now we are ultimately left with option with shared that its value lies between 7 and 8 . We know that 7² = 49 and 8² = 64. And 50 lies in between them. Therefore Option A is the correct option .

[tex]\implies \green{\text{ Option A is correct. }}[/tex]
