The designer also programs a bird with a path that can be modeled by a quadratic function. The bird starts at the vertex of the path at (0, 20) and passes through the point (10, 8). What is the slope of the line that represents the turtle's path?

Answers

Answer 1

Answer:

Answer:

-1.2

Step-by-step explanation:

Given that the designer also programs a bird with a path that can be modeled by a quadratic function.

The bird starts at the vertex of the path at (0, 20) and passes through the point (10, 8).

If we treat this curve as line joining these two points then we can find the slope by the formula

Slope = change in y coordinate/change in x coordinate

Here the points given are

(0,20) and (10,8)

$Change in y coordinate = 8-20 = -12\nChange in x coordinate = 10-0 = 10\nSlope = -1.2$

Slope of the line that represents the turtle's path

=-1.2

Jacob trims trees and mows lawns during the summer months he earns 50$ per lawn and 120$ per tree he wants to purchase a car for 4,500if Jacob plans to mow 45 lawns this summer how many trees must he trim to earn at least 4,500

Answers

Answer:

at least 19

Step-by-step explanation:

Let t represent the number of trees Jacob needs to trim. He wants ...

50(45) +120t ≥ 4500

120t ≥ 2250 . . . . . . . . . subtract 2250

t ≥ 18.75

Jacob must trim at least 19 trees to earn at least $4500.

Divide 7/15 by 3/5.
A. 75/21
B. 7/9
C. 7/25
D. 21/75

Answers

In this question there is nothing complicated. Only thing is to know the way fractions can be divided. Once that is known the problem would be one of the easiest to solve. Now let us get back to the problem and look at all the information's that are given in the question.
Divide 7/15 by 3/5 = (7/15)/(3/5)
      = (7 * 5)/(15 * 3)
   = (35/45)
Dividing the numerator and the denominator by 5 for simplifying purpose, we get
   = 7/9
So from the above deduction we can easily conclude that 7/9 is the correct answer and option "B" is the correct option among all the options given in the question.

If you would like to solve 7/15 / 3/5, you can calculate this using the following steps:

7/15 / 3/5 = 7/15 * 5/3 = 7/9

The correct result would be B. 7/9.

Ann Nguyen would like an installment loan for 5,000. Her bank will loan her the money at 12% for 18 months. Her insurance company will loan her the money at 12% for 24 months. Which loan would cost her less?

Answers

The Bank will provide loan on lesser cost.

The simple interest is given as,

$Interest=(Principle*rate *time)/(100)$

Given that, Principle is $5000$ , rate is 12 % and time is 18 months.

Time = 18 months= $(18)/(12)=1.5 years$

$Interest=(5000*12*1.5)/(100)=900$

Also, Her insurance company will loan her the money at 12% for 24 months.

$Interest=(5000*12*2)/(100) =1200$

Hence, the Bank will cost her less.

A park in a subdivision is triangular shaped. Two adjacent sides of the park are 573 feet and 536 feet. The angle between the sides is 58°. To the nearest unit, find the area of the park in square yards.

Answers

As our answers are in yards first convert from given dimensions in ft
573 / 3 = 191 yd
536 / 3 = 178.67 yd

If we draw a parallelogram with horizontal sides 191 yards long and diagonal sides 178.67 yards long at 58 degrees from horizontal, the area of the unknown triangle will be exactly half the the area of the parallelogram. The area of the parallelogram is the base length multiplied by the distance between the horizontal lines or in this case h = 178.67sin58
A = ½bh
A = ½(191)178.67sin58
A = 14470 sq yds

The circumference of the Earth is approximately 1.31 x 108 feet. If there are 5,280 feet in a mile, about how many miles is the circumference of the Earth?

Answers

The number of miles is the circumference of the Earth is 24810.60 miles.

Given that, the circumference of the Earth is approximately $1.31*10^8$ feet.

What is the circumference?

The circumference is the length of any great circle, the intersection of the sphere with any plane passing through its centre. A meridian is any great circle passing through a point designated a pole.

In 1 mile = 5280 feet

Now, the number of miles = $(1.31*10^8)/(5280)$
