Answer:

B, C, and E ([tex]x\leq -7,[/tex] The graph has a closed circle, and -7 is part of the solution.)

Step-by-step explanation:

Let's first solve the inequality of [tex]15\geq 22+x[/tex].

[tex]15\geq x+22[/tex]

[tex](15)-22\geq( x+22)-22[/tex]

[tex]-7\geq x[/tex]

[tex]x\leq -7[/tex]

So the final equation comes out to be [tex]x\leq -7[/tex].

This graph has a closed circle as it is a greater than OR equal to.

And -7 is a part of this solution as it is the number x is being compared to.

The factors of given function are (x + 4) and (x - 1)

To undestand more, check below explanation.

The modeled for algebra tiles is given as,

                 [tex]f(x)=x^{2} +3x-4[/tex]

We have to find the factors of given function.

Factoring means finding expressions that can be multiplied together to give the given equation.

If a quadratic equation can be factored, it is written as a product of linear terms.

            [tex]f(x)=x^{2} +3x-4\\\\f(x)=x^{2} +4x-x-4\\\\f(x)=x(x+4)-1(x+4)\\\\f(x)=(x+4)(x-1)[/tex]

Hence, the factors of given function are (x + 4) and (x - 1)

your work for the first one is perfect!!

the second one gives you the side lengths of x+2 and x-5. the formula for the area of a rectangle is l×w so you have to multiply (x+2)(x-5) and im sure you can figure that out but the answer to that is x^2-3x-10

you set up number 3 right, you just need to continue with the distribute property which would give you 4x^2-20x+25

number 4 is the same as the other ones and the answer is 36x^2-1

number 5 is just distributing the -z^3 into everything in the parenthesis giving you -5z^3-z^4+4z^5

I cant see all your work for number 6, but I can see that your term for c is 5, when it is actually -5. it looks like you didnt subtract it to make the quadratic equal to zero and to do that you would have to subtract 5.

tbh I cant read number 7

hope that helped :)

Answer:

Option c.

Step-by-step explanation:

From the given table, it is clear that

[tex]P(2)=\dfrac{1}{36}[/tex]

[tex]P(6)=\dfrac{5}{36}[/tex]

[tex]P(7)=\dfrac{6}{36}[/tex]

The increasing rate of probability between a sum of 2 and a sum of 6 is

[tex]r_1=\dfrac{P(6)-P(2)}{6-2}[/tex]

[tex]r_1=\dfrac{\dfrac{5}{36}-\dfrac{1}{36}}{4}=\dfrac{1}{36}[/tex]

The increasing rate of probability between a sum of 6 and a sum of 7 is

[tex]r_2=\dfrac{P(7)-P(6)}{7-1}[/tex]

[tex]r_2=\dfrac{\dfrac{6}{36}-\dfrac{5}{36}}{1}=\dfrac{1}{36}[/tex]

Since [tex]r_1=r_2[/tex], therefore the probability increases at the same rate over both intervals.

Hence, the correct option is c.

Answer:

c)the probability increases at the same rate over both intervals

Answer:

The smallest four digit number divisible by 18, 24, and 32 is 1152.

Step-by-step explanation:

The LCM of the 3 numbers are 288

Then, the smallest four-digit number would equal 1152 (288*4)

Take L.C.M. of 18,24,32= 288

Resulting in 1152 :)

Answer:

The answer would be 35066 :)

Step-by-step explanation:

(y+5554) + y = 64578

Combine like terms

2y = 64578-5554

2y = 59024

y = 29512

x = 29512 + 5554 = 35066

=======================================================

Explanation:

This is a piecewise function as it is composed of two pieces.

The equation for f(x) depends on what x is. Specifically whether it is even or odd.

If x is even, then f(x) = x^2-4. If x is odd, then f(x) = 3x-2

------------

f(4) means f(x) when x = 4. We have an even number input for x, so we'll go with f(x) = x^2-4

f(x) = x^2 - 4

f(4) = 4^2 - 4

f(4) = 16 - 4

f(4) = 12

------------

When x = 5, x is now odd, so use f(x) = 3x-2

f(x) = 3x-2

f(5) = 3(5) - 2

f(5) = 15 - 2

f(5) = 13

Answer:

15

Step-by-step explanation:

f(5) = (5)^2 - 2(5) = 25 - 10 = 15

Answer: 3060

Step-by-step explanation:

Formula : (r+1)th term of [tex](a+b)^n[/tex] : [tex]T_{r+1}=\ ^nC_r(a)^{n-r}(b)^r[/tex]

To find: Coefficient of [tex]x^{14}y^4[/tex] in the expansion of [tex](x + y)^{18}[/tex].

Let the term in the expansion of [tex](x + y)^{18}[/tex] be [tex]^{18}C_r x^{18-r}y^r=x^{14}y^4[/tex]

[tex]\Rightarrow\ r=4[/tex]

Now, Coefficient = [tex]^{18}C_r=^{18}C_4=\dfrac{18!}{4!14!}[/tex]     [[tex]^nC_r=\dfrac{n!}{r!(n-r)!}[/tex]]

[tex]=\dfrac{18\times17\times16\times15\times14!}{14!(24)}\\\\=3060[/tex]

Hence, the coefficient of [tex]x^{14}y^4[/tex] in the expansion of [tex](x + y)^{18}[/tex] is 3060 .

Step-by-step explanation:

Answer: the rate of change of the distance between the car and the person at that instant is 4 meters per second

Step-by-step explanation:

According to the Pythagorean theorem, we have:

d^2 = (12^2 + 9^2)

Differentiating both sides with respect to time:

2d * (dd/dt) = 0 + 2(9) * (9''), Simplifying the equation, we get:

2d * (dd/dt) = 2(9) * (9'')

Substituting the given values:

2d * (dd/dt) = 2(9) * (4) [the car is moving at a constant velocity of 4 m/s]

Simplifying further:

2d * (dd/dt) = 72

we divide both sides by 2d:

dd/dt = 72 / (2d)

substitute this value into the equation to find the rate of change of the distance:

dd/dt = 72 / (2 * 9) = 4 m/s

The rate of change of the distance between the car and the person at that instant is -12/5 meters per second.

Given information:

The person is standing 12 meters east of the intersection.

The car is driving away from the intersection to the north at a constant speed of 4 meters per second.

At a certain instant, the car is 9 meters from the intersection.

Using the Pythagorean theorem, determine D(t) in terms of the car's distance from the intersection, which we'll call x(t).

Since the person is 12 meters east of the intersection, the distance D(t) can be expressed as:

[tex]D(t) = \sqrt{(x(t)^2 + 12^2)[/tex]

Differentiating both sides of the equation with respect to time, we get:

[tex]dD/dt = (1/2) * (x(t)^2 + 12^2)^{(-1/2)} * 2x(t) * dx(t)/dt[/tex]

So, dx(t)/dt = -4

Substituting this value into the equation for dD/dt, we have:

[tex]dD/dt = (1/2) * (x(t)^2 + 12^2)^{(-1/2)} * 2x(t) * (-4)[/tex]

[tex]dD/dt = -4x(t) / \sqrt{(x(t)^2 + 144)[/tex]

At the instant when the car is 9 meters from the intersection, substitute x(t) = 9 into the equation:

[tex]dD/dt = -4(9) / \sqrt{(9^2 + 144)[/tex]

          = -36 / √(81 + 144)

          = -36 / √225

          = -36 / 15

          = -12/5

Therefore, the rate of change is -12/5 meters per second.

Answer:

The answer is 51

Step-by-step explanation:

f(x) = 5x + 4

g(x) = −2x + 1

To find f(6)+g(-8) first find f(6) and g(-8) and add them

For f(6) we have

f(6) = 5(6) + 4

= 30 + 4

= 34

For g(-8)

g(-8) = - 2(-8) + 1

= 16 + 1

= 17

So we have

f(6)+g(-8) is

34 + 17

= 51
