Solve the polynomial equation = 3

Answer:

[tex]\sum\limits^5_{n=1} {2^{n-2}} = 15.5[/tex]

Step-by-step explanation:

Given

[tex]\sum\limits^5_{n=1} {2^{n-2}[/tex]

Required

The result

To do this, we simply substitute 1 to 5 for n.

So, we have:

[tex]\sum\limits^5_{n=1} {2^{n-2}} = 2^{1-2} + 2^{2-2} + 2^{3-2} + 2^{4-2} + 2^{5-2}[/tex]

[tex]\sum\limits^5_{n=1} {2^{n-2}} = 2^{-1} + 2^{0} + 2^{1} + 2^{2} + 2^{3}[/tex]

Evaluate each exponent

[tex]\sum\limits^5_{n=1} {2^{n-2}} = 0.5 + 1 + 2 + 4 +8[/tex]

[tex]\sum\limits^5_{n=1} {2^{n-2}} = 15.5[/tex]

Answer:

74

Step-by-step explanation:

1. Showing your knowledge in the problem

Well, you know that a straight line is 180 degrees, right? And you know that the angles are 52 degrees and 54 degrees. So, your equation would be set up like this: 52 + 54 + ____ = 180

2. What is 52 + 54?

106

3. Subtract 180 - 106

74

Hope that helps!

Answer:

180 - 52 - 54 = 74

x = 180 - 74 = 106°

Answer:

D, 525

Step-by-step explanation:

1) Find what percent 45 is out of 150

45/150 x 100/100 = 4,500/15,000 = 30/100 = 30%

2) Find 30% of 1,750

1,750 x 0.3 = 525

Answer= D

Answer:

The value of x is 7

Step-by-step explanation:

Complementary angles have a sum of 90°, therefore the equation to solve for x is:

∠1+∠2=90°

60°+5(x-1)°=90°

5(x-1)=30°

x-1=6

x=7

So the value of x is 7

Answer:

49

Step-by-step explanation: no idea i just evaluated like that

Answer:

49

Step-by-step explanation:

Alrighty, PEMDAS, lets get started:

9 + 3(10 ÷ 2) + 5²

So we start with the parenthesis:

10 ÷ 2 = 5

Now we do the exponent:

5² = 25

So we now have:

9 + 3 x 5 + 25

we do multiplication first:

3 x 5 = 15

so we have:

9 + 15 + 25 = 49

So 9 + 3(10 ÷ 2) + 5² = 49

Answer:

x=-45/11

y=10/11

Step-by-step explanation:

y = x + 9   eq 1

3x + 8y = -5   eq 2

Re arranging eq 1

x-y=-9

Now multiply  eq 1 with 8

8x-8y=-40   now call as eq 3

Add eq 2 and 3

3x+8y=-5

8x-8y=-40

11x=-45

x=-45/11

put value of x in eq 2 for y

 3(-45/11)+8y=-5

-135/11+8y=-5

8y=-5+135/11

8y=(-55+135)/11

8y=80/11

y=(80/11)*(1/8)

y=10/11

Check

3*(-45/11)+8*(10/11)=-5

-135/11+80/11=-5

(-135+80)/11=-5

-55/11 =-5

-5=-5

⟼ A = 22/7 × 5²

⟼ A = 22/7 × 5 × 5

Answer:

Question 1: 11%

Question 2: 89%

Question 3: 43%

Question 4: 11%

Step-by-step explanation:

Looking at picture 1, we need to find the crossing point between -1.2 and 0.05. That has 0.1056, which is the same as 10.56%. 10.56% rounds to 11%, so C is our answer.

Picture 2 has the same chart, but we just need to find the inverse, since the inequality sign is flipped. 100 - 10.56 is 89.44%, which rounds to 89%, so D is the answer for Picture 2.

Picture 3 has two tables. 0.73 has 76.73% and -0.41 has 34.09%. Subtract 34.09% from 76.73% to get 42.64% That rounds to 43%, so A is the answer.

Picture 4 essentially has the same expression as Picture 2 (only the sign has switched): P(z ≥ 1.25). The meeting point is 89.44%. Now, subtract that from 100 to get 10.56%, which rounds to 11%. C is our answer for Picture 4.

I hope this helps you! ^w^

Answer:

C(g) = 27

Step-by-step explanation:

2.25(12) = 27

You just plug in your g value and solve.

It would cost $27 to buy 12 gallons of gasoline. Substitute the value of g (number of gallons) into the cost function C(g).

In the cost function C(g) = 2.25g, the variable g represents the number of gallons of gasoline we want to buy. We want to find out the cost of buying 12 gallons, so we will replace g with 12 in the equation:

C(12) = 2.25 * 12

Perform the multiplication.

Now, we simply calculate the value of 2.25 * 12:

C(12) = 27

So, the result is 27. It means that it would cost $27 to buy 12 gallons of gasoline using the given cost function C(g) = 2.25g. The cost is calculated by multiplying the number of gallons (12) by the cost per gallon (2.25).

Nurses use the quadratic equation for calculating the dosage of the patients, calculating drip rates, conversion between the systems, drug titration, and more.

Step-by-step explanation:

Nurses with an order to "give 750 mg every 4 hours as needed for pain" may receive 250 mg tablets from the pharmacy, requiring them to calculate the number of pills to administer. They also need to calculate the amount of medicine to give when drawing up liquid medicine for injection. In order to give 7.5 mg must be compared to the vial, which states, "5 mg per cc." Some medication orders require the nurse to calculate the dosage based on the patient's weight.

Quadratic equations are applicable in nursing particularly in the aspect of drug and dosage administration.

divide both sides by 50

50 cancels out b is by itself.

37.50 divide by 50= 0.75

The mistake Tory made is he divided b by 50 instead of multiplying b by 50. A correct equation is 50b = 37.50. Its solution is $0.75.

Division is a mathematical operation that involves the grouping of  a number into equal parts using another number. The sign used to denote division is ÷.

Answer:

A

Step-by-step explanation:

Area of the rectangle

L = 30

W = 21

Area = 30 * 21

Area = 630

Area of the circles

Radius = 7 m

Area = pi r^2

Area = 3.14 * 7^2

Area = 153.86 m^2

Area of both circles = 307.72

Area of the Shaded Region

Area of shaded region = area of the rectangle - area of 2 circles.

Area of Shaded Region = 630 - 307.72

Area of Shaded Region = 322.28
