The line AB is shown on the grid.
a) Find the gradient of a line
perpendicular to AB.
b) Find the equation of the line
perpendicular to AB and passing
through the midpoint of AB.

Answer:

It is: (f(2) - f(0))/(2 - 0)

f(2) = 250(0.5)(2) = 250

f(0) = 250 (0.5)(0) = 0

So: (250 - 0)/(2 - 0) = 250/2 = 175

The average rate of change is 175.

Answer:

the answer is a octagon that has rotation of 45degrees

Answer:

(6,7)

x=6

y=7

Step-by-step explanation:

What you do is combine the two equations and solve for x

1/3x+5=5/3x-3

Add three to both sides and subtract 1/3x from both as well

This gives us

8=4/3x

Divide by 4/3 and get

x=6

Then plug x=6 into any of the equations and get

1/3*6+5

This gives us 7

I have the same question,

Step-by-step explanation:

Answer:

[tex]1.159\%[/tex]

Step-by-step explanation:

Given: Principal or P [tex]=\textrm{Rs }60,000[/tex].

Rate or R [tex]=10\%[/tex] per annum compounded annually.

Time or T [tex]=2[/tex] years.

To find: Percentage difference between compound interest of first year and second year.

Solution:

First year interest [tex]=\frac{\textrm{P}\times \textrm{R}\times \textrm{T}}{100}=\frac{60000\times 10\times 1}{100}=\textrm{Rs }6000[/tex].

First year amount [tex]=\textrm{Rs }60,000+\textrm{Rs }6,000=\textrm{Rs }66,000[/tex].

For the second year, the interest is compounded semi-annually.

So, time is doubled and the rate is halved.

Second year compounded amount [tex]=66,000\times [1+\frac{10}{2\times 100}]^2=66,000\times1.1025=\textrm{Rs }72,765[/tex].

Second year compound interest [tex]=\textrm{Rs }72,765-\textrm{Rs }66,000=\textrm{Rs }6,765[/tex].

Difference in interest of first and second year [tex]=\textrm{Rs }6,765-\textrm{Rs }6,000=\textrm{Rs }765[/tex].

Percentage difference [tex]=\frac{765}{66000}\times 100\%=1.159\%[/tex].

Hence, the percentage difference between compound interest of first year and second year is [tex]1.159\%[/tex].

Answer:

a) 13%

b) 45%

c) 16%

Step-by-step explanation:

To calculate what percentage is one number (a) of another (b), you have to divide a by b and then multiply result by 100. In this case number of students with grade A is 4, total number of students is 31,  therefore 4/31 * 100 = 12.9%. Rounding it to the nearest percentage will give you 13.

Answer:

4x + 1 is the simplified expression

Step-by-step explanation:

We have to use order of operations in order to solve. We basically need to simplify it with multiplication and addition.

The first step involves mulitplication and distribution property:

1) Do 1/2(4x + 2). If you use distribution property, it would be 1/2(4x) + 1/2(2)

2) Then use multiplication 1/2(4x) is 2x (since 4 multiplied by 1/2 is 2) and 1/2(2) is 1 (since 1/2 times 2 is 1).

Bow the expression is almost simplified as it is:

2x + 1 -(-2x)

The 2nd stop involves addition. First we have to know what -(-2x) means. Think of the negative sign on the outside as -1. This way it would be:

3) -1(-2x), and then do -1(-2) which is 2 since a negative times a negative is positive.

4) Now we know that -(-2x) is the same as: + 2x.

5) So the expression would be 2x + 1 + 2x. Combine like terms ( 2x and 2x) and you will get 4x + 1.

Step-by-step explanation:

If it’s mathswatch you don’t need an explanation just type in the answer it gives you all the marks <3

The value of the angle,x=50.531°. The angle is obtained by the sin law.

A triangle is a polygon that has three sides and three angles. The sum of the angle of the triangle is 180 degrees.

From the sin rule;

[tex]\rm \frac{AB}{sin \angle ACB} =\frac{BC}{sin \angle BAC} \\\\ \rm \frac{5.6}{sin \angle ACB} =\frac{9.3}{sin \angle 50^0} \\\\ \angle ACB=27.49^0[/tex]

For the same angles;

[tex]\rm \angle ACB=\angle BCD[/tex]

From the exterior angle theorm ;

[tex]\rm \angle BCD+\angle CBD= \angle ADB[/tex]

∠CBD=x

∠ABD=78°

Putting the obtained values;

27.469°+x=78°

x=78°-27.469°

x=50.531°

Hence,the value of the angle,x=50.531°.

Answer:   a square with side length 4 inches

a 2 inch by 8 inch rectangle

a heart-shaped base with an area of 16 square inches

Step-by-step explanation: The given height is 5. Any base with an area of 16 square inches will be an acceptable base.

For example, if the circular base had a radius of about 2.257 inches, its area would be 16 square inches

(2.257)² ≈ 5.093

5.093 × 3.1416 ≈ 16

16 × 5 = 80

The base for this prism should be like

a square with side length 4 inches.

a 2 inch by 8 inch rectangle.

a heart-shaped base with an area of 16 square inches.

Since

The given height is 5.

Any base with an area of 16 square inches should be considered as an acceptable base.

Like if the circular base had a radius of about 2.257 inches, its area would be 16 square inches

So, it be like
