Answer:

Step-by-step explanation:

Thinking process:

This is a question of vectors.

There are a few things to remember about vectors:

A point AB is denoted by the notation AB, starting from the point of origin to the end point.

In the answers, CR satisfies the question

AC is the opposite, so it is rejected as the direction is not the same as the arrow.

Similarly, RC is rejected

AR is the point somewhere on the line not the origin.

This leaves us with CR as the correct answer.

How do I calculate this? Is there a formula?

Answer:

Height of cables = 23.75 meters

Step-by-step explanation:

We are given that the road is suspended from twin towers whose cables are parabolic in shape.

For this situation, imagine a graph where the x-axis represent the road surface and the point (0,0) represents the point that is on the road surface midway between the two towers.

Then draw a parabola having vertex at (0,0) and curving upwards on either side of the vertex at a distance of $x = 600$ or $x = -600$ , and y at 95.

We know that the equation of a parabola is in the form $y=ax^2$ and here it passes through the point $(600, 95)$ .

$y=ax^2$

$95=a \times 600^2$

$a=\frac{95}{360000}$

$a=\frac{19}{72000}$

So new equation for parabola would be $y=\frac{19x^2}{72000}$ .

Now we have to find the height $(y)$ of the cable when $x= 300$ .

$y=\frac{19 (300)^2}{72000}$

y = 23.75 meters

The Math Club is sponsoring a bake sale. If their goal is to raise at least $300, how many pies must they sell at $6.00 each in

soldi70 [24.7K]

Given:
bake sale at least $300
price of each pie is $6.00
let the number of pies be represented by x.

Write the inequality:
6x > 300

Solve the inequality:
6x > 300
÷6 ÷6
x > 50

Graph the inequality.
y = 6x

x is the number of pies sold; x at least 50 and gradually increases.
y is the total sales

Some of the children at a school arrrive by car.

dedylja [7]

Answer:

0.36

Step-by-step explanation:

Percentage of boys = 60%

Percentage of girls = 100 - 60 = 40%

Percentage of boys that arrive by car

= 20% of 60%

= 0.2 x 60 = 12%

Percentage of girls that arrive by car

= 60% of 40%

= 0.6 x 40

= 24%

Total Percentage of children arrive by car

= 12 + 24

= 36%

P(Arrive by car)

= 36%

= 0.36
