Answer:

the measure of angle 4 should be 45

Step-by-step explanation:

since angle 2 and 4 are congruent, 2x+15 = x + 30

so x = 15

15 + 30 = 45

Answer: x = 41

Step-by-step explanation: You need to isolate x. First, subtract x from each side. You will get:

Answer:

the answer to this question is b.

Answer:

The correct option is B.

Step-by-step explanation:

It is given that In a population of 1000 individuals, 100 new individuals were born and 200 individuals died over the course of 1 year.

We need to find the population growth rate of this population.

Rate of birth = [tex]\frac{100}{1000}=0.10[/tex]

Rate of death = [tex]\frac{200}{1000}=0.20[/tex]

The formula for rate of change is

Rate of change = Rate of birth - Rate of death

Rate of change = 0.10 - 0.20

Rate of change = -0.10

The required equation is 0.10 - 0.20 = -0.10.

Therefore, the correct option is B.

Answer:

1) (2x - 3)(x + 5)

2) 1.5, -5

3) Open upwards from both ends

4) Minimum

Step-by-step explanation:

Step 1:

The given polynomial is:

[tex]2x^{2}+10x-3x-15[/tex]

Taking out commons, we get:

[tex]2x(x+5)-3(x+5)\\\\ =(2x-3)(x+5)[/tex]

This is the factorized form of the polynomial.

Step 2:

The zeros of the functions occur when the function is equal to zero.

i.e.

[tex](2x-3)(x+5)=0\\\\ \text{According to the zero product property}\\\\ 2x-3=0, x+5=0\\\\ x =\frac{3}{2}=1.5, x = -5[/tex]

This means, the zeros of the polynomial are 1.5 and -5

Step 3:

The end behavior of a graph depends on its degree and the sign of leading coefficient. Since the degree is even and the coefficient is positive the graph of the polynomial will opens upwards from left and right side.

Step 4:

The given polynomial is a quadratic function with positive leading coefficient. Since it open vertically upwards, its vertex will be the lowest most point. So, the vertex will be the minimum of the function.

Answer:

Answer in factored form: [tex]P(x)=(x+2)(x-7)(x-5)^2[/tex]

Answer in standard form: [tex]P(x)=x^4-15x^3+61x^2+15x-350[/tex]

Step-by-step explanation:

I don't see your choices but I can still give you a polynomial fitting your criteria. I will give the answer in both factored form and standard form.

The following results are by factor theorem:

So if x=-2 is a zero then x+2 is a factor.

If x=7 is a zero then x-7 is a factor.

If x=5 is a zero then x-5 is a factor.  It says we have this factor twice.  I know this because it says with multiplicity 2.

So let's put this together.  The factored form of the polynomial is

A(x+2)(x-7)(x-5)(x-5)

or

[tex]A(x+2)(x-7)(x-5)^2[/tex]

Now A can be any number satisfying a polynomial with zeros -2 and 7 with multiplicity 1, and 5 with multiplicity 5.

However, it does say we are looking for a polynomial function with leading coefficient 1 which means A=1.

[tex](x+2)(x-7)(x-5)^2[/tex]

Now the factored form is easy.

The standard form requires more work (multiplying to be exact).

I'm going to multiply (x+2)(x-7) using foil.

First: x(x)=x^2

Outer: x(-7)=-7x

Inner: 2(x)=2x

Last: 2(-7)=-14

--------------------Adding.

[tex]x^2-5x-14[/tex]

I'm going to multiply [tex](x-5)^2[/tex] using formula [tex](u+v)^2=u^2+2uv+v^2[/tex].

[tex](x-5)^2=x^2-10x+25[/tex].

So now we have to multiply these products.

That is we need to do:

[tex](x^2-5x-14)(x^2-10x+25)[/tex]

I'm going to distribute every term in the first ( ) to

every term in the second ( ).

[tex]x^2(x^2-10x+25)[/tex]

[tex]+-5x(x^2-10x+25)[/tex]

[tex]+-14(x^2-10x+25)[/tex]

------------------------------------------ Distributing:

[tex]x^4-10x^3+25x^2[/tex]

[tex]+-5x^3+50x^2-125x[/tex]

[tex]+-14x^2+140x-350[/tex]

-------------------------------------------Adding like terms:

Answer:

The zero's are -1, -2/5, 8

Step-by-step explanation:

f(x) = (x + 1)(x − 8)(5x + 2)

We can use the zero product property

0 = (x + 1)(x − 8)(5x + 2)

0 = x+1   0 = x-8   0 =5x+2

x=-1     x=8      -2 =5x

x=-1     x=8      -2/5 =x

The zero's are -1, -2/5, 8

Answer:

ƒ(x) = (x - 1)(x - 2)(x - 3)  

Step-by-step explanation:

The graph shown is that of a cubic equation with zeros at x = 1, 2, and 3

The function in factored form must be

ƒ(x) = (x - 1)(x - 2)(x - 3).

When you solve for the zeros, the sign of the constant changes. For example

x - 1 = 0

   x = 1

Answer:

4/7

Step-by-step explanation:

P(A or B) when A and B are disjointed is P(A)+P(B)

P(A or B)=P(A)+P(B)

P(A or B)=1/7 +3/7

P(A or B)=4/7

The value of P(A or B) is 4/7 (3rd option)

Let A and B be two disjoint events.

Then, probability of A is P(A) & probability of B is P(B).

In this case, the probability of A or B is the sum of P(A) & P(B)

∴ P(A or B) = P(A) + P(B)

Given, P(A) = 1/7 & P(B) = 3/7

So, P(A or B) = P(A) + P(B)

                     = 1/7 + 3/7

                     = (1+3)/7

                     = 4/7

Required value of P(A or B) is 4/7

Answer:

C. [tex]0\le x\le55,-1.45[/tex]

Step-by-step explanation:

The domain of the function refers to all values of x for which the function is defined.

From the diagram the graph of the function exist on the interval [tex]x=0[/tex] to [tex]x=55[/tex].

The average rate of change is the slope of the secant line joining the points (0,f(0)) and (55,f(55)).

The average rate of change of this function f(x) on this interval is

[tex]\frac{f(55)-f(0)}{55-0}[/tex]

From the graph, [tex]f(0)=80[/tex] and [tex]f(55)=0[/tex].

The average rate of change becomes:

Step-by-step explanation:

46,880

Since this is an even number, we can divide by 2

46,880/2 =23440

Since this number ends in either a 0 or a 5 we can divide by 5

46880/5 =9376

Since the number is divisible by 2 and 5, we know it is divisible by 10

46880/10 =4688

The only number we need to check is 4

If the last 2 numbers are divisible by 4 then the number is divisible by 4

80/4 = 20  so the number is divisible by 4

46880/4 =11720

46880 is divisible by 4,2,10,5

Answer:

8x^3-46x^2-5x+18

Step-by-step explanation:

The volume of a rectangular prism is L*W*H where

L=length

W=width

H=height.

So we want to probably find the standard form of this multiplication because writing (4x+3)(x-6)(2x-1) is too easy.

Let's multiply (4x+3) and (x-6), then take that result and multiply it to (2x-1).

(4x+3)(x-6)

I'm going to use FOIL here.

First:  4x(x)=4x^2

Outer:  4x(-6)=-24x

Inner:  3(x)=3x

Last:   3(-6)=-18

---------------------------Add.

4x^2-21x-18

So we now have to multiply (4x^2-21x-18) and (2x-1).

We will not be able to use FOIL here because we are not doing a binomial times a binomial.

We can still use distributive property though.

(4x^2-21x-18)(2x-1)

=

4x^2(2x-1)-21x(2x-1)-18(2x-1)

=

8x^3-4x^2-42x^2+21x-36x+18

Now the like terms are actually already paired up we just need to combine them:

8x^3-46x^2-5x+18

Answer:

[tex]\large\boxed{8x^3-46x^2-15x+18}[/tex]

Step-by-step explanation:

The formula of a volume of a rectangular prism:

[tex]V=lwh[/tex]

l - length

w - width

h - height

We have l = 4x + 3, w = x - 6 and h = 2x - 1.

Substitute:

[tex]V=(4x+3)(x-6)(2x-1)[/tex]

use FOIL: (a + b)(c + d)

[tex]V=\bigg[(4x)(x)+(4x)(-6)+(3)(x)+(3)(-6)\bigg](2x-1)\\\\=(4x^2-24x+3x-18)(2x-1)\qquad\text{combine like terms}\\\\=(4x^2-21x-18)(2x-1)[/tex]

use the distributive property: a(b + c) = ab + ac

[tex]V=(4x^2-21x-18)(2x)+(4x^2-21x-18)(-1)\\\\=(4x^2)(2x)+(-21x)(2x)+(-18)(2x)+(4x^2)(-1)+(-21x)(-1)+(-18)(-1)\\\\=8x^3-42x^2-36x-4x^2+21x+18[/tex]

combine like terms

Answer:

(x+1) (x^2+6)

Step-by-step explanation:

Taking an x^2 from the first two terms and a 6 from the last two terms

x^2(x+1) +6(x+1)

Now we can factor out an (x+1)

Step-by-step explanation:

1 / tan(90 - x) = -√3/3                   Cross multiply

3 = -√3 * tan(90 - x)                     Divide by -√3

3/-√3 = tan(90 - x)                       Rationalize the denominator

3 * √3 /  (- √3 * √3  ) =tan(90-x)

3 * √3 / - 3 = tan(90 - x)               Divide

- √3           = tan(90 - x)               Take the inverse tan of -√3

tan-1(-√3) = 90 - x

-60 = 90 - x                                  Add x to both sides.

x - 60 = 90                                   Add 60 to both sides

15500=9.0909090909091*x       - we divide both sides of the equation by (9.0909090909091) to get x

15500/9.0909090909091=x  

1705=x  

x=1705

Check the picture below, that's just an example of a parabola opening upwards.

so the cost equation C(b), which is a quadratic with a positive leading term's coefficient, has the graph of a parabola like the one in the picture, so the cost goes down and down and down, reaches the vertex or namely the minimum, and then goes back up.

bearing in mind that the quantity will be on the x-axis and the cost amount is over the y-axis, what are the coordinates of the vertex of this parabola?  namely, at what cost for how many bats?

[tex]\bf \textit{vertex of a vertical parabola, using coefficients} \\\\ C(b) = \stackrel{\stackrel{a}{\downarrow }}{0.06}b^2\stackrel{\stackrel{b}{\downarrow }}{-7.2}b\stackrel{\stackrel{c}{\downarrow }}{+390} \qquad \qquad \left(-\cfrac{ b}{2 a}~~~~ ,~~~~ c-\cfrac{ b^2}{4 a}\right)[/tex]

[tex]\bf \left( -\cfrac{-7.2}{2(0.06)}~~,~~390-\cfrac{(-7.2)^2}{4(0.06)} \right)\implies (60~~,~~390-216) \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ ~\hfill (\stackrel{\textit{number of bats}}{60}~~,~~\stackrel{\textit{total cost}}{174})~\hfill[/tex]

To find the number of bats that should be produced to minimize costs, we need to find the minimum point on the cost curve given by the function C(b) = 0.06b^2 - 7.2b + 390. Using the vertex formula, we find that the minimum occurs at b = 60.

To find the number of bats that should be produced to keep costs at a minimum, we need to determine the minimum point on the cost curve given by the function C(b) = 0.06b^2 - 7.2b + 390. The minimum point of a quadratic function can be found using the vertex formula: b = -b / (2a), where a is the coefficient of the quadratic term and b is the coefficient of the linear term. In this case, a = 0.06 and b = -7.2. Plugging these values into the formula, we get b = -(-7.2) / (2 * 0.06) = 60.

Therefore, the number of bats that should be produced to keep costs at a minimum is 60.

Answer:

D. (4, -4)

Step-by-step explanation:

Convert to vertex form by completing the square.

For a polynomial y = x² + bx + c, first add and subtract (b/2)² to the polynomial.  Then factor.

Here, b = -8.  So (b/2)² = (-8/2)² = 16.

y = x² − 8x + 12

y = x²− 8x + 16 − 16 + 12

y = (x − 4)² − 16 + 12

y = (x − 4)² − 4

The vertex is (4, -4).

The vertex of the function y = x2 - 8x + 12 is found by first using the formula -b/2a to find the x-coordinate of the vertex, and then substituting that value into the equation to find the y-coordinate. This results in the vertex being at the point (4,-4).

The vertex of a quadratic function given in the form y = ax2 + bx + c is found using the formula -b/(2a) for the x-coordinate, and substituting that value into the equation to find the y-coordinate. In the given function y = x2 - 8x + 12, a is equal to 1, and b is equal to -8.

Using the vertex form, the x-coordinate of the vertex can be found by using -b/2a, or --8/(2*1), which equals 4. This becomes the x-coordinate of our vertex. Substituting x = 4 into our equation, we find y = (4)2 - 8*4 + 12 = -4. Therefore, the vertex of the given graph is at the point (4,-4), which corresponds to option D.
