Which equation represents a population of 370 animals that increases at an annual rate of 11% ?

Answers

Answer:

D.

Step-by-step explanation:

the starting number is 370 and it gets multiplied by 1.11 every year so you would root the equation by t

The equation fourth represents the population of 370 animals that increases at an annual rate of 11% option fourth is correct.

What is an exponential function?

It is defined as the function that rapidly increases and the value of the exponential function is always positive. It denotes with exponent y = a^x

where a is a constant and a>1

We have:

A population of 370 animals that increases at an annual rate of 11%

Initial value a = 370

rate r = 11% = 0.11

The equation:

[tex]\rm p = a(1 + r)^t[/tex]

[tex]\rm p = 370(1 + 0.11)^t[/tex]

Thus, the equation fourth represents the population of 370 animals that increases at an annual rate of 11% option fourth is correct.

Find the image of (-1, 3) obtained by translating
2 units down, followed by a rotation of 180°
counterclockwise about the origin.
HELP QUICK

Answers

Answer:

(1, - 1 )

Step-by-step explanation:

A translation of 2 down means subtract 2 from the y- coordinate

(- 1, 3 ) → (- 1, 3 - 2 ) → (- 1, 1 )

Under a counterclockwise rotation about the origin of 180°

a point (x, y ) → (- x, - y ) , then

(- 1, 1 ) → (1, - 1 )

Overall

(- 1, 3 ) → (- 1, 1 ) → (1, - 1 )

The image of (-1, 3) was obtained by translating 2 units down, followed by a rotation of 180° counterclockwise about the origin is (1,-1).

What is coordinate?

A coordinate system in geometry is a system that employs one or more integers, or coordinates, to define the position of points or other geometric components on a manifold such as Euclidean space.

The given point with coordinates of (-1,3), when translated downwards will have the coordinated equal,

(-1,3) ⇒ (-1, 3-2) ⇒ (-1, 1)

Now, since the translation is about 180° in the counter-clockwise direction, the coordinates of the new point will be equal to,

(-1,1) ⇒ (1, -1)

Hence, the image of (-1, 3) obtained by translating 2 units down, followed by a rotation of 180° counterclockwise about the origin is (1,-1).

Karima earns $400 per week plus a holiday bonus of $250. Write an expression to represent the total amount she earns after working w weeks. Then, find the amount she earns after she works 4, 12, and 36 weeks.
Expression:
Earnings at 4 weeks:
Earnings at 12 weeks:
Earnings at 36 weeks:

Answers

Answer:

Step-by-step explanation:

Earnings per week = $ 400

Earning for 'w' week = 400*w + holiday bonus

                                   = 400w + 250

Earnings at 4 weeks = 400*4 + 250

                                   = 1600 + 250

                                   = $ 1850

Earnings at 12 weeks = 400*12 + 250

                                   = 4800 + 250

                                   = $ 5050

Earnings at 36 weeks = 400*36 + 250

There are 1024 bytes in a kilobyte. Write an expression that describes the number of bytes in a computer chip with n kilobytes. helpppp ​

Answers

Bytes are used to represent the number of bits in a computer system. There are 1024n bytes in n kilobytes.

Using the following representation:

[tex]KB \to[/tex] Kilobyte

[tex]B \to[/tex] Bytes

1024 bytes in 1 kilobyte is represented as:

[tex]1024B = 1KB[/tex]

Let the number of bytes in n kilobytes be x.

So, we have:

[tex]x = n\ KB[/tex] and

[tex]1024B = 1KB[/tex]

Cross multiply

[tex]x \times 1KB = 1024B \times nKB[/tex]

Divide both sides by KB

[tex]x \times 1 = 1024B \times n[/tex]

[tex]x = 1024n\ B[/tex]

Remove the units for proper representation

[tex]x = 1024n[/tex]

Hence, there are 1024n bytes in n kilobytes

Write the slope-intercept form of the equation of the line through the given point with the givenslope.

Answers

Answer:

[tex]y=6x-5[/tex]

Step-by-step explanation:

Hi there!

Slope-intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept

We're given that the slope is 6. Plug this into [tex]y=mx+b[/tex] as m:

[tex]y=6x+b[/tex]

Now, to solve for the y-intercept, plug in the point (1,1) and solve for b:

[tex]1=6(1)+b\\1=6+b\\b=-5[/tex]

Therefore, the y-intercept of the line is -5. Plug this back into [tex]y=6x+b[/tex]:

[tex]y=6x+(-5)\\y=6x-5[/tex]

Step-by-step explanation:

hope it helps you

The expressions are evaluated using distributive property below -

We have -

i. 425 x 136

ii. 4005 x 67

We have to evaluate them with help of distributive property.

State the  property of distributivity of multiplication over addition.

Distributive property of multiplication over addition :  

a × (b + c) = a × b + a × c

According to question, we have -

i. 425 x 136

ii. 4005 x 67

Now -

425 x 136 = 425 x (6 + 30 + 100) = 425 x 6 + 425 x 30 x 425 x 100

and

4005 x 67 = 4005 x (60 + 7) = 4005 x 60 + 4005 x 7

Hence, the evaluation using distributive property is done.

Calculate the volume of a warehouse that has inside dimensions of 22.4 meters by 11.3 meters by 5.2 meters.

Answers

I think it should be 1316.22 cubic meters

The volume of the warehouse with the three dimensions is V = 1,316.224 cubic meters.

Given data:

To calculate the volume of the warehouse, you need to multiply its length, width, and height:

Volume = Length *  Width * Height

The volume of the rectangle is given by the product of the length of the rectangle and the width of the rectangle and the height of the rectangle

Given the dimensions:

Length = 22.4 meters

Width = 11.3 meters

Height = 5.2 meters

Substitute these values into the formula:

Volume = 22.4 m × 11.3 m × 5.2 m

Calculate the result:

Volume = 1,316.224 m³

So, the volume of the warehouse is approximately 1,316.224 cubic meters.

A library wishes to build an access ramp for wheelchairs. The main entrance of the library is 8 ft. above sidewalk level. If the architect recommends a grade (angle of elevation) of 6°, how long must the access ramp be?​

Answers

Answer:

About 76.5 ft.

Step-by-step explanation:

Draw a diagram of a right triangle.  The shorter leg represents the height of the main entrance of the library, which is 8 ft.  The longer leg won't matter in this case.  The hypotenuse is what we're trying to find, so mark it as x.  We know there's a 6° angle of elevation, so the 30° angle of the triangle will be 6° in this case.  Now we have to use trig.  Think of Soh Cah Toa.  The 6° is opposite from 8 and the hypotenuse is x.  So, the equation to find x would be:

sin (6°) = 8/x

Multiply both sides by x

sin (6°) * x = 8

Divide both sides by sin (6°)

x = 8/sin (6°)

When putting it into a calculator, your answer should be 76.534, which rounds to 76.5 ft.
