Answer:5.14

Step-by-step explanation:

THIS ANSWER WAS DELETED DUE TO NOT BEING TRUE.

The correct value of m = 6 and b = -9.

The function f(x) is differentiable at x = 3 and we know that if a function is differentiable at some point means that it is continuous at that point also.

Here function is continuous at x = 3 piecewise

m(3) + b = (3)²

3m + b = 9 .....(1)

and function is differentiable at ( x = 3 ) piecewise

d/dx ( m * x + b ) = d/dx (x)² at ( x= 3 )

( m + 0 ) = 2x  at ( x = 3 )

m = 2 * 3

m = 6

By placing the value of m in equation (1)

3m + b = 9

3 * 6 + b = 9

18 + b = 9

b = 9 - 18

b = -9

Therefore, the value of m = 6 and b = -9.

Answer:

What is the sum equal to?

Step-by-step explanation:

The probability that if 3 donations are made, all 3 of them can be safely used on blood transfusion with someone that has type A will be D. (0.27 + 0.49)³ = 0.4390

It should be noted that probability simply means the chance that a particular event will occur.

In this case, the probability that if 3 donations are made, all 3 of them can be safely used on blood transfusion with someone that has type A will be:

= (27% + 49%)³

= (0.27 + 0.49)³

= 0.4390

The probability is 0.4390.

Answer:  It's not linear.

Step-by-step explanation: A linear function must have a degree of 0 or 1. This function equals to y= -1/x. -1/x has a degree of negative 1 since x^-1 =1/x. So this is not linear.

Answer: 164 degrees

Step-by-step explanation:

IHG=JHG+IHJ

19x-7=84+7x+17

19x-7=101+7x

12x-7=101

12x=108

x=9

IHG=19x-7

IHG=19(9)-7

IHG=171-7

IHG=164 degrees

Answer:

-2

Step-by-step explanation:

You have to simplify numerator and denominator through factoring. The you should get an expression involving only a + b which is given as -2

Take numerator
[tex]a^2-b^2-12b-36[/tex]

Factor
[tex]-b^2-12b-36[/tex]

[tex]= - (b^2 + 12b + 36)\\\\= -(b+6)^2[/tex]

So numerator becomes
[tex]a^2-\left(b+6\right)^2[/tex]

Apply difference of squares formula: [tex]\displaystyle x^2-y^2=\left(x+y\right)\left(x-y\right)[/tex]

[tex]\mathrm{with\;} x^2 == > a^2, and y^2 == > (b + 6)^2[/tex]

[tex]\implies a^2-\left(b+6\right)^2 \\== \left(a+\left(b+6\right)\right)\left(a-b-6\right)[/tex]

Denominator
[tex]a^2-6a-b^2-6b[/tex]

can be factored as follows

[tex]a^2-b^2 = (a + b) (a -b)[/tex]
[tex]-6a-6b = -6\left(a+b\right)[/tex]

So denominator becomes
[tex]\left(a+b\right)\left(a-b\right)+-6\left(a+b\right)[/tex]

Factor out common term (a+b) to get
[tex]\left(a+b\right)\left(a-b-6\right)[/tex]

So the original expression with Numerator and denominator

[tex]\displaystyle =\frac{\left(a+b+6\right)\left(a-b-6\right)}{\left(a+b\right)\left(a-b-6\right)}[/tex]
Cancel the common factor (a-b-6) to get
[tex]\displaystyle \frac{a+b+6}{a+b}[/tex]

Since a + b = -2, plug in this value of (a+b) in both numerator and denominator to get
[tex]\displaystyle \dfrac{-2 + 6}{-2}[/tex]
[tex]\displaystyle = - 2[/tex]

The formula in terms of H is H = V ÷ πr². Value of height is 5.

We are given the formula -

V = πr²H, where V represents volume and H represents height. To rewrite the formula in terms of H, we will shift it to Left Hand Side -

H = V ÷ πr²

Keep the value of Volume and radius in formula to find the height.

H = 45π ÷ π(3)²

Taking square of 3 and cancelling π

H = 45 ÷ 9

Performing division to find the value of height

H = 5

Therefore, the formula is V ÷ πr² and value of height is 5.

4K = 120 can be used to find the number of emergency kits K Elise packs. The total number of emergency kits packed by Elsie and her mom are 30.

Here, we are given that Elise puts 4 water bottles into each emergency kit.

Let the number of kits packed = K

Then the total number of bottles packed = 4 × K

= 4K

Also, we are given that Elsie packs a total of 120 bottles.

Thus, we get the following linear equation-

4K = 120

We can use this equation to find the number of emergency kits K Elise packs.

dividing by 4 on both sides, we get

4K/4 = 120/4

K = 30

Hence, the total number of emergency kits packed by Elsie and her mom are 30.

Answer: 21

Step-by-step explanation:

Use a calculator

The answers of the following part are:

a) 22

b) -76

c) -13

For solving this particular sum we need to know the about functions Function is generaaly defined as a set of inputs having one output each. every function as a domain and a co-domain or range. A function is generally denoted by f(x) where x is the variable and it is also the input.The general representation of function is y = f(x).

In the given sum we will just put the values in place of x and will find the answer

The given equation is f(x)=-13+7x

a) Here it is given f(5)  so we will put 5 in all places of x

Substituting the value x as 5 we will get :

f(5) = -13+7*5

= -13+35

=22

the value f(5) will be 22

b) In this part of the vaule of x is given as -9

Substituting the value of x as -9 we get

f(-9)=-13+7*(-9)

= -13-63

= -76

the valur of f(-9) is -76

c) here the value of x is given as 0

Substituting the value of x as 0

f(0)= -13+7*0

= -13+0

=-13

The number sold at the original price is 27 and they sold 64 at the reduced price.

Let x = number of pieces sold at 13.50

Let y = number of pieces sold at 9.50

The equation will be:

x + y = 91. ..... i

13.50x + 9.50y = 972.50 ..... ii

From equation i x = 91 - y

13.50x + 9.50y = 972.50

13.50(91 - y) + 9.50y = 972.50

1228.50 - 13.50y + 9.50y = 972.50

1228.50 - 4y = 972.50

4y = 1228.50 - 972.50

4y = 256

y = 256/4

y = 64

Since x + y = 91

x = 91 - 64 = 27

Therefore, the number sold at the original price is 27 and they sold 64 at the reduced price.

The mass, in grams, of 1 cubic centimeter of the sand in scientific notation is 7 x 10^(-1).

Scientific notation is a way of writing very large or very small numbers.

Now it is given that,

Average mass of grain = 7 x 10-4 gram

Number of grains in 1 cubic centimeter = 1,000 grains =  10^3 grains

Thus,

Mass of 1 cubic centimeter of the sand = Average mass of grain * Number of grains in 1 cubic centimeter

⇒ Mass of 1 cubic centimeter of the sand =  7 x 10-4 * 10^3 grams

⇒ Mass of 1 cubic centimeter of the sand =  7 x 10^(-4+ 3) grams

⇒ Mass of 1 cubic centimeter of the sand =  7 x 10^(-1) grams

Thus, the mass, in grams, of 1 cubic centimeter of the sand in scientific notation is 7 x 10^(-1).

Answer:          410 possible points

To solve for the possible points in the course, use a proportion and cross multiply.

A proportion is two fractions that are equal to each other. For the fractions to be equal, they are proportionate. In our math problem, percentage is proportionate the the number of points.

The fractions represent information you have, and one variable will represent what you are solving for.

Your points = 361

Points to get an 'A' = your points + 8

'A' = 90% of possible points

Points to get an 'A' = your points + 8

= 361 + 8

= 369

let x be the amount of possible points

We know the number of points for 90% is 369 points. Remember that 90% is the same as 90/100.

Keep the information with the same units inside the same fraction. Here, percentage is represented by the first fraction. Points is represented by the second fraction.

[tex]\displaystyle{\frac{90}{100}=\frac{369}{x}}[/tex]

We can solve using cross multiplication. This is when we multiply each numerator by the denominator from the other fraction.

[tex]90x = 369*100[/tex]        Simplify by multiplying.

[tex]90x = 36,900[/tex]            Isolate the variable x.

[tex]\displaystyle{\frac{90x}{90} = \frac{36,900}{90}}[/tex]           Divide both sides by 90 to cancel out 90 on the left.

[tex]\displaystyle{x = \frac{36,900}{90}}[/tex]              Divide.

[tex]x = 410[/tex]                    Solved for x, representing the possible points.
