A model rocket is launched from ground level. Its height, h meters above the ground, is a function of time t seconds after launch and is given by the equation . What would be the maximum height, to the nearest meter, attained by the model? (First find the axis of symmetry x= (-b/2a), then plug this value into the equation)

Answers

Answer:

The maximum height attained by the rocket is 240.1 m.

Step-by-step explanation:

The height above the ground is a function of time t is given by :

[tex]h= -4.9t^2 + 68.6t[/tex] ...(1)

We need to find the maximum height of the model. First we find the time of max height using axis of symmetry of the equation as follows :

[tex]x=\dfrac{-b}{2a}[/tex]

We have, a = -4.9 and b = 68.6

So,

[tex]t=\dfrac{-(68.6)}{2\times -4.9}\\\\=7\ s[/tex]

Put t = 7 in equation (1)

[tex]h= -4.9(7)^2 + 68.6(7)\\\\=240.1\ m[/tex]

So, the maximum height attained by the rocket is 240.1 m.

"Leo and Stan start to ride their bikes at the same time from the same point on a

circular track. If it takes Leo 36 seconds to complete on revolution around the

track and it takes Stan 40 seconds to make one revolution around the track, how

many minutes will it take for them to meet again at the starting point?



I need help?

Answers

Answer:

6 minutes

Step-by-step explanation:

Given

Leo = 36 sec / rev

Stan = 40 sec/rev

Required

Determine the time (in minutes) they'll meet again

We start by getting the multiples of 36 and 40 uptil we get a common multiple.

Leo: 36 = 36, 72, 108, 144, 180, 216, 252, 288, 324, 360, .....

Stan: 40 = 40, 80, 120, 160, 200, 240, 280, 320, 360....

From above, the common multiple is:

Common Multiple = 360

This means that they'll meet at 360 seconds

Convert to minutes

360 sec = 360/60 mins

360 Seca = 6 mins

Hence,it will take them 6 minutes to meet again at the starting point

Erin is buying pizza for 12 people. She estimates that each person will eat 3 slices of pizza. Erin also knows that each pizza will cost $15.25 and will be cut into 8 slices. Which expression can be used to calculate the amount of money Erin needs for pizza?

Answers

Answer:

Total cost= 15.25*[(12*3)/8]

Step-by-step explanation:

The expression would be:

Total cost= 15.25*[(12*3)/8]

Prove:

Number of slices= 12 people*3 slices

Number of slices= 36

Number fo pizzas= number of slices/8

Number of pizzas= 36/8

Number of pizzas= 4.5 = 5 pizzas

Now, the total cost:

Total cost= number of pizzas*unitary cost

Total cost= 5*15.25

Total cost= $76.25

Evaluate when f(-3) and f(7)
f(x) = {3x-1,tfx>4
{2x,tfx<4
_

Answers

Answers:

f(-3) = -6f(7) = 20

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

Explanation:

The piecewise function f(x) changes based on what the input is.

We have two cases:

Case A) if x > 4, then f(x) = 3x-1Case B) If [tex]x \le 4[/tex], then f(x) = 2x

The input x = -3 satisfies the inequality [tex]x \le 4[/tex], so we go with case B for this input

f(x) = 2x

f(-3) = 2(-3)

f(-3) = -6

In contrast, the input x = 7 satisfies the inequality x > 4. So we go for case A this time.

f(x) = 3x-1

f(7) = 3(7)-1

f(7) = 21-1

f(7) = 20

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

Side note: It might be better to let g(x) = 3x-1 and h(x) = 2x. Then we could further say "If x > 4, then f(x) = g(x) OR if [tex]x \le 4[/tex], then f(x) = h(x)". Though this might be a more wordy definition.

What is an equation of the line that passes through the point (6,−4) and is perpendicular to the line 2x−y=5?

Answers

Answer:

An equation of the line that passes through the point (6,−4) and is perpendicular to the line will be:

[tex]y=-\frac{1}{2}x-1[/tex]

Step-by-step explanation:

We know that the slope-intercept form of the line equation

y = mx+b

where m is the slope and b is the y-intercept

Given the line

[tex]2x-y=5[/tex]

converting the line into slope-intercept form

y = 2x-5

comparing with the slope-intercept form of the line equation

The slope of the line = m = 2

We know that a line perpendicular to another line contains a slope that is the negative reciprocal of the slope of the other line, such as:

slope = m = 2

Thus, the equation of new line = – 1/m = -1/2 = -1/2

using the point-slope form of the line equation

[tex]y-y_1=m\left(x-x_1\right)[/tex]

where m is the slope of the line and (x₁, y₁) is the point

substituting the values of the slope = -1/2 and the point (6,−4)

[tex]y-\left(-4\right)=-\frac{1}{2}\left(x-6\right)[/tex]

[tex]y+4=-\frac{1}{2}\left(x-6\right)[/tex]

Subtract 4 from both sides

[tex]y+4-4=-\frac{1}{2}\left(x-6\right)-4[/tex]

[tex]y=-\frac{1}{2}x-1[/tex]

Therefore, an equation of the line that passes through the point (6,−4) and is perpendicular to the line will be:

[tex]y=-\frac{1}{2}x-1[/tex]

An equation of the line  that passes through the point (6,−4) and is perpendicular to the line 2x−y=5 is [tex]y=-\frac{1}{2}x-1[/tex]

Given:

An equation of the line that passes through the point (6,−4) and is perpendicular to the line 2x−y=5

First we find the slope of given equation 2x-y=5

y=mx+b is the equation of the line . where 'm' is the slope

[tex]2x-y=5\\2x-5=y\\y=2x-5[/tex]

Slope m=2.

Slope of perpendicular lines are negative reciprocal of one another

Slope of perpendicular line is [tex]-\frac{1}{2}[/tex]

The line passes through the point (6,-4)

Use the point and slope to get the equation of the perpendicular line

slope m = [tex]-\frac{1}{2}[/tex]

Point slope form of line is

[tex]y-y_1=m(x-x_1)\\y+4=-\frac{1}{2}(x-6)\\y+4=-\frac{1}{2}x+3\\y=-\frac{1}{2}x-1[/tex]

An equation of the line  that passes through the point (6,−4) and is perpendicular to the line 2x−y=5 is [tex]y=-\frac{1}{2}x-1[/tex]

Well, it seems that for every week, Pragitha swims x + 2 laps. So if she swims x + 2 laps twice, she will get 2x + 4. So x is equal to 4. You add that four and you get three x. So for one week, she swims x + 2 laps and for the second lap, she swims 2x + 4. Which according to the table, is equal to 3x. So for 3 weeks, she clearly swims less, because maybe she's tired or something. So it's 2x+1. And for week 4, it's week one and week 2 combined.

What are the coordinates of the point on the directed line segment from

Answers

Answer:

(- 1, - 3 )

Step-by-step explanation:

Given endpoints (x₁, y₁ ) and (x₂, y₂ ) partitioned in the ratio m : n

Then using the Section formula the coordinates of the point are

( [tex]\frac{nx_{1}+mx_{2} }{m+n}[/tex], [tex]\frac{ny_{1}+my_{2} }{m+n}[/tex] )

Here (x₁, y₁ ) = (- 4, - 9), (x₂, y₂ ) = (1, 1) and m : n = 3 : 2 , then

( [tex]\frac{2(-4)+3(1)}{3+2}[/tex] , [tex]\frac{2(-9)+3(1)}{3+2}[/tex] )

What is Slope?

The slope of a line is a number that describes both the direction and the steepness of the line.

Given that a line is passing through the points  (3,4) and (7,-4).

Slope = ([tex]y_{2}[/tex] - [tex]y_{1}[/tex])/([tex]x_{2}[/tex] - [tex]x_{1}[/tex])

Michael is leaving a 15% tip for his waitress. What percent of the
original price will he pay? Write your answer as a percent, decimal,

Answers

Answer:

Percentage: 115%

Decimal: 1.15

Fraction: [tex]\frac{23}{20}\\[/tex]

Step-by-step explanation:

Percentages, Fractions, and Decimals

Assume we set 100% as the original price of the food that Michael consumed. When he leaves a 15% tip for the waitress, he is really paying 100%+15%=115% of the original price.

Now we express 115% as a decimal, simply dividing by 100:

115% = 115/100 = 1.15

To express it as a fraction, we simplify the division instead of calculating it:

115% = [tex]\frac{115}{100}[/tex]

Simplifying by 5:

115% = [tex]\frac{23}{20}[/tex]
