Answer:

BC is 24 units

Step-by-step explanation:

Given that: AB = 7 units

                  EC = 18 units

From a sketch for the question, we have a triangle ABC. Such that:

AC = AE + EC

But,

AE = AB = 7             (radius of the circle)

So that,

AC = 7 + 18

     = 25 units

Applying Pythagoras theorem to triangle ABC, we have:

[tex]/AC/^{2}[/tex] = [tex]/AB/^{2}[/tex] + [tex]/BC/^{2}[/tex]

[tex]25^{2}[/tex] = [tex]7^{2}[/tex] + [tex]/BC/^{2}[/tex]

[tex]/BC/^{2}[/tex] = 625 - 49

          = 576

BC = [tex]\sqrt{576}[/tex]

     = 24

Thus, BC is 24 units.

Answer:

-26.

Step-by-step explanation:

Substitute the numbers and letters like this

-6 + (-5 x 4)

Which would evaluate to -6 + -20

And since it's the same sign, you can make it -6 - 20.

That equals -26.

Answer:

The mistake was converting the expresssion

Step-by-step explanation:

The distance traveled after 4 hours is 260 miles.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x + 4 - 9 = 9  is an equation.

We have,

Distance ∝ Time

Distance = K x Time

Now,

390 = 6K

K = 390/6

K = 65

Now,

Distance = 65 x 4

Distance = 260 miles

Thus,

After 4 hours the distance traveled is 260 miles.

Answer:

  1. (-∞, ∞), [-4, ∞), (2, ∞), (-∞, 2), (-∞, 0) ∪ (4, ∞), (0, 4), DNE, -4, 2

  2. y = -|x -4| -2

Step-by-step explanation:

1.

a. the domain is the horizontal extent, (-∞, ∞)

b. the range is the vertical extent, [-4, ∞)

c. the function is increasing where it goes up to the right, (2, ∞)

d. the function is decreasing where it goes down to the right, (-∞, 2)

e. the function is positive where it is above the x-axis, (-∞, 0) ∪ (4, ∞)

f. the function is negative where it is below the x-axis, (0, 4)

g. the function extends to ∞, so has no maximum value

h. the vertex is the low point, or minimum value, -4

i. the function increases from -4 to 0 on the interval [2, 4] so has an average rate of change of (0 -(-4))/(4 -2) = 4/2 = 2

2. Reflection across the x-axis negates every y-value. Multiply the given function by -1:

Answer:

4x^2 - 2x

Step-by-step explanation:

Area of Maria's garden = 8x^2 - 4x

Jamal's garden

Width = 3x

Length = 4x - 2

Area of Jamal's garden = length × width

= (4x - 2) (3x)

= 12x^2 - 6x

Difference in area of Jamal's garden and Maria's garden

Jamal's garden - Maria's garden

(12x^2 - 6x) - (8x^2 - 4x)

12x^2 - 6x - 8x^2 + 4x

4x^2 - 2x

The difference is the areas of their garden is 4x^2 - 2x

Answer: Choice C) There are 3000 milliliters in 3 liters

mL is the abbreviation for milliliters

L is the abbreviation for liters

Since 1000 mL = 1 L, we can multiply both sides by 3 to get 3000 mL = 3 L

Steps have justified that;

y = $250 + $340x

Step-by-step explanation:

We are told Lewis is saving for a down payment of $8,750 on a house.

Now, the initial amount of money he has saved is $250, while the amount of money he plans on saving every month is $340.

Thus, if x represents the number of months and y represents the total amount of savings. It means that;

For x number of months, he saves; $340x

Now, the initial amount he saved is $250.

This means that the total amount he would have saved after x number of months is;

Total amount saved = Initial savings + Amount saved monthly after x number of months.

Now, total amount saved is denoted as y as given in the question, then we have;

y = $250 + $340x

Answer:

subtraction

y-250=340x

division

y-340=250x

Answer:

-10* F

Step-by-step explanation:

What confuses me is that the answers you have provided aren't correct, when I made a number line starting at 0 and ending at -23* F and I had counted three degrees for each hour I got -10* F.

   2am     3am      4am       5am

0 -1 -2 -3 -4 -5 -6 -7 -8 -9 -10 -11 -12 -13 -14 -15 -16 -17 -18 -19 -20 -21 -22 -23

2am is at -1* F, 3am is at -4* F, 4am is at -7* F, and 5am is at -10* F.

This is over the course of three hours after 2am so unless I got this wrong you might want to ask your teacher.

Answer:

Step-by-step explanation:

Let the area of the rectangle be Length × width

LW = 8000

If the diagonal is 10feer greater than one of its length then:

D = 10+L

Diagonal is represented using the Pythagoras theorem as shown:

D² = L²+W²

(10+L)²= L²+W²

100+20L +L² = L²+W²

From LW = 8000

W = 8000/L

100 + 20L = (8000/L)²

100 +20L = 64,000,000/L²

Cross multiply

100L² + 20L³ = 64,000,000

2L³+10L² = 6,400,000

L³+5L² = 3200000

L³+5L² -3200000 = 0

Answer:

55 ft by 146 ft

Step-by-step explanation:

Given the following :

Area of rectangle = 8000 ft^2

Area of rectangle = length(L) * width(W)

Let length of a side = x

Length of side 2 = 8000 / x

Diagonal = 10 feet longer than one side = (x + 10)

The diagonal is the hypotenus = (x + 10)²:

Hyp² = (8000/x)² + x²

(x + 10)² = (8000/x)² + x²

x² + 20x + 100 = 64,000,000 / x² + x²

20x + 100 = 64,000,000 / x²

(20x + 100) * x² = 64,000,000

20x³ + 100x² - 64,000,000 = 0

x³ + 5x² - 3200000 = 0

Using calculator

x = 145. 71 = 146 ft

8000 / x

8000/145.71

= 54.9 ft

= 55ft

55ft by 146 ft
