The sum of three numbers is -39.22. One of the numbers is 22.8. The other two numbers are equal to each other. What is the value of the other two numbers?

Answer:

b = 33 miles

Step-by-step explanation:

The illustration forms a right angled triangle. The opposite side of the triangle is where we are looking for . The adjacent side is the radius 4000 miles.

5280 ft = 1 mile

735 ft = ? miles

cross multiply

735/5280

miles = 0.13920454545  miles

The hypotenuse side is the height of the building + 4000 miles = 0.140 + 4000 = 4000.14  miles

using Pythagoras theorem

c² = a² + b²

c = 4000.14

a = 4000

4000.14² = 4000² + b²

b² = 4000.14² - 4000²

b² = 16001120.0196  - 16000000

b² = 1120.0196

b = √1120.0196

b = 33.4666938911

b = 33 miles

The radius of the circle is 10.5.

Pythagorean theorem states that for a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

We can apply this theorem only in a right triangle.

Example:

The hypotenuse side of a triangle with the two sides as 4 cm and 3 cm.

Hypotenuse side = √(4² + 3²) = √(16 + 9) = √25 = 5 cm

We have,

AC = 20 and BC = 17

From the figure,

We apply the Pythagorean theorem.

So,

AC² = BC² + AB²

Substituting,

20² = 17² + AB²

AB² = 400 - 289

AB² = 111

Now,

Radius = AB

So,

AB = √111

AB = 10.535

Rounding to the nearest tenth.

AB = 10.5

Thus,

The radius of the circle is 10.5.

Answer:

  10. Expanded vertically by 3, shifted left 2 and up 4.

  11. Shifted right 6 and up 7.

Step-by-step explanation:

This sort of question involves matching patterns. You need to know what the various transformations look like, and what that means for a specific parent function.

Here are the transformations used in this problem:

For these problems, the parent function is f(x) = 1/x.

__

10. The multiplier of 3 in the numerator (3/x) means the function has been scaled vertically (expanded) by a factor of 3.

The replacement of x with x+2 means the function has been shifted to the right by -2 units. That is the same as shifted left 2 units.

The addition of 4 to the function value means the function has been shifted up by 4 units.

__

11. We note the numerator is still 1, so there is no vertical expansion. The replacement of x with x-6 means a right shift by 6 units. The addition of 7 to the function value means a shift up by 7 units.

Answer:

Step-by-step explanation:

The rate of growth (the slope of the transformed curve) is first higher than for an exponential function, but later it goes down. ... Initially, the quadratic function grows much faster. The function x² grows from 0 to 1 in finite time, while the exponential function takes from minus infinity to 0.

Answer:

9 and 15

Step-by-step explanation:

Let the greater number be x and the smaller number be y.

x +y= 24 -----(1)

x -y= 6

x= y +6 -----(2)

Substitute (2) into (1):

y +6 +y= 24

2y +6= 24 (simplify)

2y= 24 -6 (-6 on both sides)

2y= 18

y= 18 ÷2

y=9

Substitute y= 9 into (2):

x= 9 +6

x= 15

Thus the numbers are 9 and 15.

Answer:

Lin should expect to sell 10 cups more

Step-by-step explanation:

The line c = 2t − 89 relates the cups Lin expect to sale (c) with the high temperature of the day (t)

If high temperature on Saturday is t1, then high temperature on Sunday is (t1+5)

Cups sold on Saturday are: 2t1 − 89

Cups sold on Sunday are:  2(t1+5) − 89 = 2t1 + 10 - 89

Cups sold on Sunday - Cups sold on Saturday:

2t1 + 10 - 89 - (2t1 − 89) = 2t1 + 10 - 89 - 2t1 + 89 = 10

Final answer:

The population of a city with an initial population of 300,000 and an 11% annual growth rate can be modeled by the exponential growth equation [tex]y = 300,000(1 + 0.11)^x,[/tex] where x represents the number of years.

Explanation:

To model the population growth of the city with an initial population of 300,000 and an annual growth rate of 11%, we use an exponential growth equation. This type of growth can be represented by the equation y = P(1 + r)^x, where P is the initial population, r is the growth rate in decimal form, and x is the number of years.

For this scenario, P = 300,000 and r = 0.11 (since 11% as a decimal is 0.11). Therefore, the equation to model the population, y, after x years is:[tex]y = 300,000(1 + 0.11)^x,[/tex]

This equation assumes that the growth rate remains constant over the years and that there are no other factors affecting the population size.

Answer:

S = {-1, 0, 1}

Step-by-step explanation:

First we need to solve the inequation x^2<=3

Using square root in both sides, we have:

|x| <= 1.73

Separating the module in two, we have:

x <= 1.73

x >= 1.73

So we have that -1.73 <= x <= 1.73

Solving this inequation only with integer values, we have:

x = -1, x = 0 or x = 1

So the set of integer solutions is S = {-1, 0, 1}

Answer:

Total area= 207 ft^2

Step-by-step explanation:

You can divide the figure to make 2 big rectangles.

The first has a base of 15 ft and a height of 15 ft

A1 = b * h

A1= 15 ft * 9 ft        A1= 135 ft^2

The second has a base of 12 ft and a height of 6 ft

A2= b*h

A2= 12 ft * 6 ft

A2= 72 ft^2

Total area= A1+A2= 135 ft^2 + 72 ft^2  

Total area= 207 ft^2

Thoughtfully split the expression at hand into groups, each group having two terms :

Group 2:  a3-5a2  

Pull out from each group separately :

Group 1:   (4a+5) • (1)

Group 2:   (a-5) • (a2)

Bad news !! Factoring by pulling out fails :

The groups have no common factor and can not be added up to form a multiplication.
