What is an equation of the line that passes through the points (-6,-5) and (-3,0)?put your answer in fully reduced form

Answers

Step-by-step explanation:

The equation is y = -3x + 6.

Answer:

3y = 5x + 15

Step-by-step explanation:

Slope = Change in y-cordinates

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

Change in x-cordinates

= 0 - (-5)/-3 - (-6)

= 5/3

Using point (-3,0)

y - y1 = m(x - x1)

y - 0 = 5/3 (x - (-3))

y = 5/3 (x + 3)

Expand the bracket

y = 5x/3 + 15/3

Multiply through by 3

3y = 5x + 15

Answer:

b = -6.307 or -11.693

Step-by-step explanation:

[tex]b^{2} +9b +13\\[/tex]

This can't be factored so you need to use the quadratic formula which is

-b ± [tex]\frac{\sqrt{b^{2} -4ac}}{2a}[/tex]

Plugging the numbers from the equation in, it's

-(9) ± [tex]\frac{\sqrt{(9)^{2}-4(1)(13) } }{2(1)}[/tex]

This simplifies down to b = -6.307 or -11.693.

These are both real solutions.

b = -6.307 or -11.693

One large bubble separates into four small bubbles so that the total area of the small bubbles is equal to the area of the large bubble. Each small bubble has a radius of 5 centimeters. What is the radius of the large bubble?

Answers

find area of 1 small bubble

πr² = π × 5²

= 78.54

total area of 4 small bubble

78.54 × 4 = 314.16

total area of 4 small bubble = area of big bubble

= 314.16

find it's radius

πr² = 314.16

r² = 314.16 ÷ π

r² = 100

r = √100

r = 10

Answer:

AREA OF LARGE BUBBLE=PI×R^2

AREA OF 1 SMALL BUBBLE =PI×r^2

then area of 4 small bubble =(PI×r^2)×4

now,

area of large bubble =area of 4 small bubble

PI×R^2=4×(PI×r^2)

R= 10 cm

Rick bought a car for $17,500. Each year, the car's value decreases by 20%. At this rate, what can Rick expect the value of his car to be in 6 years? *
$1.12
$15,502.24
$4,587.52
$17,380.00

Answers

Answer:

His car would be worth $15,502.24

Step-by-step explanation:

20% of 17,500 is 350. 350 x 6 = 2,100. 17,500 - 2,100 = 15,400. But that is not an answer choice so be go to  the closest number which is $15,502.24

What’s 142,000,000 written in scientific notations

Answers

1.42 x 108 in scientific notation

Answer:

1.42 x 10^8

Step-by-step explanation:

For a number to be in scientific notation, it has to be between 1 and 10, so for it to meet that criteria, we would have to put the decimal point between the 1 and 4. The exponent is equal to the amount of numbers after the decimal point. We know that we have 2 numbers with the 4 and 2, and if you add all the 0s to that, we get 8. So the exponent will be 8. We add those two elements together, we get our answer, 1.42 x 10^8.

Why is the surface area of a triangular prism measured in square units rather than in cubic units? Surface area measures the area of the faces. Area is a -dimensional measurement, so it is measured in square units.

Answers

Answer:

Step-by-step explanation:

Area of a given figure is a 2 dimensional measurement which describes the amount of space occupied by the figure, while volume of the figure describes its capacity in a 3 dimensional measurement.

The surface area of a triangular prism is the sum of the areas of all its surfaces. Since the surface area considers the areas of the figure not volume, therefore the surface area of the triangular prism is measured in square units not cubic units.

Answer:

[tex]\Huge\boxed{57.475 ft^2}[/tex]

Step-by-step explanation:

Hello there!

The following figure shown is a triangle

The area of a triangle can be calculated using this formula

[tex]A=\frac{bh}{2}[/tex] where b = base and h =height

The height of the triangle is 12.1 ft and the base length is 9.5ft

Knowing this information all we have to do is plug in the values into the formula

[tex]A=\frac{12.1*9.5}{2} \\12.1*9.5=114.95\\\frac{114.95}{2} =57.475\\A=57.475[/tex]

So we can conclude that the area of the triangle is 57.475 square feet
