Graph f(x) = −16x^2 + 22x + 3

Answer:

25; 15^2+20^2=625. 25^2=625, therefore the answer is 25.

Answer:

The probability is 1/24

Step-by-step explanation:

For a 12-sided dice, there are 12 different possible results

so the possibility of rolling a 7 is just one of the results

The probability of this is simply 1/12

For landing on head, the probability is 1/2

So the probability of the event occurring is the product of these two events

We have this as;

1/2 * 1/12 = 1/24

Given:

The area model for [tex]2.1\times 3.2[/tex].

To find:

The value of [tex]2.1\times 3.2[/tex] and the missing values in the area model.

Solution:

2.1 can be written as 2 and 0.1 on the left side of the area model.

3.2 can be written as 3 and 0.2 on the top of area model.

Area of the four parts of the area model are:

[tex]2\times 3=6[/tex]

[tex]2\times 0.2=0.4[/tex]

[tex]0.1\times 3=0.3[/tex]

[tex]0.1\times 0.2=0.02[/tex]

The complete area model is shown below.

After adding all areas of the area model, we get

[tex]6+0.4+0.3+0.02=6.72[/tex]

Therefore, the value of [tex]2.1\times 3.2[/tex] is 6.72 and the missing values of the area model are 0.3 and 0.02 respectively.

Can you post a picture of the triangle? it would make this way easier.

Answer:

m<A=94

Step-by-step explanation:

(2x+10)+(2x+2)=180

4x+12=180

-12 -12

4x=168

/4 /4

x=42

m<A= 2x+10

m<A=2(42)+10

m<A=84+10

m<A=94

Check:

Add m<A and m<B which should equal 180.

m<B=2x+2

m<B=2(42)+2

m<B=84+2

m<B=86

94+86=180

Answer:

A, and B

Step-by-step explanation:

I think they are the correct answer

Answer:

B = -1

Your answer would be C

Answer:

b = -1

Step-by-step explanation:

-3(2x - 3) + 5x = bx + 9

-3 x 2x = -6x

-3 x -3 = 9

-6x + 9 + 5x = bx + 9

-6x + 5x = -1x

-1x + 9 = bx + 9

(cancel out everything except -1 and b)

-1 = b

Answer:B i think if wrong im so sorry

Step-by-step explanation:

Answer:

B 75+25h

Step-by-step explanation:

$75 is the first charge for the service and is constant. $25(per hour) is not constant and changes as the time (hours) changes. That's why it has a h next to it, the h is the variable to hold the place for the hours that would be multiplied in the problem.

Responder:

2280 pneus.

Explicação passo a passo:

Dado que :

Número máximo de pneus que o caminhão pode transportar de uma vez = 456

Se o caminhão fizer 5 viagens;

O número de pneus que serão transportados na capacidade máxima é:

Capacidade máxima do caminhão * número de viagens

456 * 5

= 2.280 pneus.

Answer:

f(x) = (x - 3)(x - 4)

Step-by-step explanation:

EDG2021

Answer: l=50 m, w=20 m

Step-by-step explanation:

Given

A rectangular city has an area of [tex]1000\ m^2[/tex]

Also, length is 10 m more than twice its width

suppose width is w

So, length is given by

[tex]\Rightarrow l=10+2w[/tex]

The area is given by

[tex]\Rightarrow A=l\times w\\\Rightarrow 1000=(10+2w)\times w\\\Rightarrow 2w^2+10w-1000=0\\\Rightarrow w^2+5w-500=0\\\Rightarrow w^2+25w-20w-500=0\\\Rightarrow (w+25)(w-20)=0\\\therefore w=20\ m\\l=10+2w=10+2\times 20=50\ m[/tex]

Answer:

3a+5b

Step-by-step explanation:

Variable 1:  a = candy corn

Variable 2: b = chocolate

Inequality 1:  60 ≥ 3a + 5b

Inequality 2: 20 ≤ 3a + 5b

The inequalities are as such because Josh needs to spend no greater than $60.  He must also buy at least 20 bags of candy.  The candy corn costs $3, while the chocolate costs $5.  An expression for the total cost of the candy would be 3a + 5b.

Answer:

x/x+1

Step-by-step explanation:

[tex]\frac{4n}{4n-4} * \frac{n-1}{n+1}[/tex]

start by reducing the 4n-4 by distributing the 4 to make it 4(x-1)

So the fraction would be 4n/4(x-1)

Now that you have done that you can easily take off the 4 as well as the x-1 thats now in the parentheses

The new equation would be

n*n-1/n+1

Now just multiply:

x/x+1
