Answer:

b. y = - 2x² – 3x + 5

Step-by-step explanation:

If you check on a graphing calculator or desmos, you will see that the parabola opens down, so there is a highest point, or a maximum. You can also know that without a calculator by looking at the sign in front of x. Since answer choice b is the only one with a negative in front (meaning that the parabola opens down giving you a maximum) then you will know that that's the correct answer.

Answer:

Axis of symmetry: x = 2

Vertex at: (2, -13)

y-intercept is (0, -5)

Step-by-step explanation:

The equation for the x-value of the vertex in a quadratic of the form:

[tex]y=ax^2+bx+c[/tex]

is given by:

[tex]x_{vert}=-\frac{b}{2\,a}[/tex]

which in our case gives:

[tex]x_{vert}=\frac{8}{2*2} =2[/tex]

Then the equation for the axis of symmetry is given by:  x = 2

and the y of the vertex can be calculated as:

[tex]y_{vert}=2 (2)^2-8\,(2)-5=-13[/tex]

Then the vertex is at the point: (2, -13)

And the y-intercept is found when x=0, that is:

y-intercept is (0, -5)

4 * 4 = 16

Hope this helped. Please give brainly if its the best!

Answer:

[tex] \huge \colorbox{blue}{16 students}[/tex]

Step-by-step explanation:

we are given the ratio of students and teachers:

[tex] \displaystyle \: \frac{21}{4} [/tex]

which means if the number of students is 21 then the number of teachers should be 4

to find how many teachers should go if students 84 we have to divide 84 by [tex]21/4[/tex] :

[tex] \displaystyle \: 84 \div \frac{21}{4} [/tex]

simplify division:

[tex] = \displaystyle \: 84 \times \frac{4}{21} [/tex]

simplify multiplication:

[tex] = \displaystyle \: \cancel{ 84} \: ^{4} \times \frac{4}{ \cancel{21}} \\ = 4 \times 4 \\ = 16 [/tex]

Answer:

reflect it about the x axis and  stretch it  by 2 in the y direction

Step-by-step explanation:

f(x) = |x|  to f (x)=-2|x|

y = −f(x)  Reflects it about x-axis

y = Cf(x)  C > 1 stretches it in the y-direction

so we reflect it about the x axis and  stretch it  by 2 in the y direction

Answer: reflect it about the x axis and stretch it by 2 in the y direction

Answer:

It takes takes them 31.67 secs to meet after Person A starts walking

OR

34.67 secs after Person B starts walking

Step-by-step explanation:

First, we will find the perimeter of the rectangle

From,

Perimeter of rectangle = 2 ([tex]l[/tex] + [tex]b[/tex])

Where [tex]l[/tex] is the length

and [tex]b[/tex] is the breadth

From the question, [tex]l[/tex] = 100m

and [tex]b[/tex] = 50m

Hence,

Perimeter of the rectangle = 2 (100+50)

= 2(150) = 300m

Hence, the perimeter of the rectangle is 300m

This is the total distance that will be covered by both persons by the time they meet.

Let the distance covered by person A be [tex]S_{1}[/tex]

and the distance covered by person B be [tex]S_{2}[/tex]

We can write that

[tex]S_{1}[/tex] + [tex]S_{2}[/tex] = 300m

Velocity of person A, [tex]V_{A}[/tex] = 4 m/s

and velocity of person B, [tex]V_{B}[/tex] = 5 m/s

From the question, Person A starts walking 3 seconds after person B,

This means, if person A spends [tex]t[/tex] secs before they meet, then person B would spend (3 + [tex]t[/tex]) secs.

For Person A,

Velocity = 4 m/s

Time = [tex]t[/tex] secs

Distance = [tex]S_{1}[/tex]

From,

[tex]Velocity = \frac{Distance}{Time}[/tex]

Then,

[tex]Distance = Velocity \times time[/tex]

[tex]S_{1} = 4 \times t[/tex]

[tex]S_{1} = 4t[/tex] ...... (1)

For Person B

Velocity = 5 m/s

Time = (t + 3) secs

Distance = [tex]S_{2}[/tex]

Also, from

[tex]Distance = Velocity \times time[/tex]

[tex]S_{2} = 5 \times (3+t)[/tex]

[tex]S_{2} = 5(3+t)[/tex] ...... (2)

Recall that, [tex]S_{1}[/tex] + [tex]S_{2}[/tex] = 300m

Then, [tex]S_{2}[/tex] = 300m - [tex]S_{1}[/tex]

We can then write that,

300m - [tex]S_{1}[/tex] [tex]= 5(3+t)[/tex]

Then,

[tex]S_{1} = 300 - 5(3+t)[/tex] ..... (3)

Equating equations (1) and (3), we get

[tex]300 - 5(3+t) = 4t[/tex]

[tex]300 - 15 -5t = 4t\\9t = 285\\t = \frac{285}{9}\\[/tex]

[tex]t = 31.67 secs[/tex]

This is the time spent by Person A

Hence, it takes takes them 31.67 secs to meet after Person A starts walking OR

34.67 secs after Person B starts walking

Answer:

(-infinity, 0]

Step-by-step explanation:

I'm assuming you meant  f(x) = -4x^2.  If so, the graph is that of a parabola that opens down and has vertex at (0, 0).  In other words, f(x) is always zero or below zero.

Thus the range is (-infinity, 0]

Answer:

w1 = (-1/11, 1/11, -3/11)

w2 = (12/11, 21/11, 3/11)

Step-by-step explanation:

Direction ratio of w1 = Direction ratio of L (because parallel) = K+(1, -1, 3)

Let <a,b,c> be direction ratio of w2.

Then, <a,b,c>. <1,-1,3> = 0

a-b+3c = 0

v = w1 + w2

(1, 2, 0) = k(1, -1, 3) + (a, b, c)

a + k = 1

b - K = 2

c - 3k = 0

Solving 4 equations, a = 12/11, b= 21/11, c = 3/11, k=-1/11

So, w1 = -1/11(1, -1 ,3) = (-1/11, 1/11, -3/11)

w2 = (12/11, 21/11, 3/11)

Answer:

[tex]y-4=9[/tex]

The opposite of subtraction is addition, so you would have to add 4 to both sides:

[tex]y-4+4=9+4[/tex]

[tex]y=13[/tex]

The value of the y for the equation,y – 4 = 9  will be y=13 and e have to apply the subtraction operation must be applied to both sides in order to isolate the variable y.

The subject of arithmetic operations includes the study of numbers and their operations, which are important to all other branches of mathematics. These systems' fundamental operations are addition, subtraction, multiplication, and division.

It is given that the equation is,y – 4 = 9.

We have to solve the equation y – 4 = 9 and find the operation that must be applied to both sides in order to isolate the variable y.

The following steps are to be taken to isolate the variable y.

y – 4 = 9

y-4+4=9+4

y=13

Thus, the value of the y in the equation, y - 4 = 9, will be 13, and in order to isolate the variable y, the subtraction operation must be done on both sides.

The question is incomplete. Here is the complete question.

The initial mass of a certain species of fish is 7 millions tons. The mass of fish, if left alone, would increase at a rate proportional to the mass, with a proportionality constant of 2/yr. However, comercial fishing removes fish mass at a rate of 15 million tons per year.

(a) When will all fish be gone?

(b) If the fishing rate is changed so that the mass of fish remains constant, what should the rate be?

Answer: (a) t = 1.35 years.

              (b) Rate = 14,000,000

Step-by-step explanation:

(a) Initial mass is [tex]m_{0}[/tex] = 7,000,000

Rate of increase and comercial fishing gives an equation of growth:

[tex]\frac{dm}{dt}=2m-15,000,000[/tex]

m' - 2m = - 15,000,000

This is an ordinary linear equation (ODE) of first order, of type:

y' + a(x)y = f(x)

where a(x) and f(x) are continuous.

To solve this type of linear equation, first calculate integrating factor, using:

[tex]u(x) = e^{\int\limits {a(x)} \, dx }[/tex]

In our case,

[tex]u(t) = e^{\int\limits {-2} \, dt }[/tex]

Solving:

[tex]u(t) = e^{-2t }[/tex]

The general solution of a ODE can be written as

[tex]y=\frac{1}{e^{u(x)}}[\int\ {u(x).f(x)} \, dx + c][/tex]

In our case:

[tex]m=\frac{1}{e^{-2t}}[\int\ {-2t.(-15)} \, dt + c][/tex]

Solving:

[tex]m=\frac{1}{e^{-2t}}[\frac{15}{2}e^{-2t}+c ][/tex]

To find constant c, use initial condition, i.e., m(0)=7,000,000:

[tex]7,000,000=\frac{1}{e^{-2.0}}[\frac{15}{2}e^{-2.0}+c ][/tex]

[tex]c=-500,000[/tex]

Then for the fish growth, general equation is:

[tex]m=7500,000-500,000e^{2t}[/tex]

When the fish is gone, means m = 0, then:

[tex]7500,000-500,000e^{2t}=0[/tex]

[tex]500,000e^{2t}=7500,000[/tex]

[tex]e^{2t}=15[/tex]

[tex]ln(e^{2t})=ln(15)[/tex]

[tex]t=\frac{ln(15)}{2}[/tex]

t = 1.35

It will take 1.35 years for the fish to be gone.

(b) For the mass to be constant, rate of growth must be zero:

[tex]\frac{dm}{dt}=0[/tex]

Suppose the changed fishing rate is k:

[tex]2m_{0}-k=0[/tex]

[tex]-k=-2.7,000,000[/tex]

k = 14,000,000

To remain constant, rate must be 14,000,000.

Answer:

$26.48

Step-by-step explanation:

First you find out what 6 percent OF 24.99 dollars is,

OF stands for multiplication

so multiply 6 percent of 24.99

= 0.06 x 24.99

=  $1.4994 (That's a point not a comma, so it's around 1 dollar)

Then once you have found the sales tax which we found up there, you add it to the total cost of the shirts. (If it was a discount you would subtract it because it's a discounted price which means it's less - just another tip :) )

Anyway so you add it to the price,

24.99 + 1.49

= $26.48

Step-by-step explanation:

So we have the equation:

[tex](6h+8)-(3h+2)=15[/tex]

First, let's distribute the negative:

[tex](6h+8)+(-3h-2)=15[/tex]

Combine like terms:

[tex](6h-3h)+(8-2)=15[/tex]

Subtract or add:

[tex]3h+6=15[/tex]

Subtract 6 from both sides:

[tex]3h=9[/tex]

Divide both sides by 3:

[tex]h=3[/tex]

And we're done!

Answer:

h=3

Step-by-step explanation:

1 Remove parentheses.

6h+8-3h-2=156h+8−3h−2=15

2 Simplify  6h+8-3h-26h+8−3h−2  to  3h+63h+6.

3h+6=153h+6=15

3 Subtract 66 from both sides.

3h=15-63h=15−6

4 Simplify  15-615−6  to  99.

3h=93h=9

5 Divide both sides by 33.
