Graph the function y=8- square root -2x+6. Which is the best approximation of a point on the function?

Answers

Answer 1

Answer:

D. {5.9,3.781}

Step-by-step explanation:

The equation of the function is given as;

[tex]y=8-\sqrt{2x+6}[/tex]

You can use a graph tool to graph and view the graph;

From the graph attached, the point that gives a correct approximation of the function is : {5.9,3.781}

Using this in the equation, to test the coordinates will give;

3.781= 8-√{2*5.9 +6}

3.781 = 8 -√17.8

3.781 = 8-4.219

3.781 = 3.7809

A bakery has 36 glazed donuts on display. This is 80% of the total number of donuts. What is the total number of donuts in the bakery?

Answers

Answer:

it is 64.8, but you have to round to the nearest number, so i would say 65 :)

Step-by-step explanation:

Answer:

Step-by-step explanation:

% means out of 100, so 80% is 80/100

Let's divide 100/80 to find a scale we can use to multiply 36, 100/80 =

36 times 1.25 = 45

There's 45 donuts

Double check:

45(80/100) = 36, we're right

Swim floats are on sale at sam’s shop. They are marked 30% off of the original price of 18.00. How much will the float cost

Answers

Answer:

the cost is now $5.40

Step-by-step explanation:

if 18.00 is 100%, and we need to find the new price we need to make 30% into a decimal. which is 0.3. then we multiply 0.3 times 18.00, and that equals 5.4, but since we are dealing with money the answer would be $5.40.

we multiply if we are trying to find the new amount and we divide to find the old amount.

Answers

Answer:

Step-by-step explanation:

The equation of the line that passes through the point begin ordered pair, negative 6, 1, end ordered pair and has a slope of begin fraction . . . negative 1 over 2 . . . end fraction is y=-1/2x-2.

What is Slope of Line?

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

Slope is -1/2

Using point-slope form, the equation of the line can be written as:

y - y₁ = m(x - x₁)

Substituting the values given in the problem, we get:

y - 1 = (-1/2)(x - (-6))

y-1=-1/2(x+6)

y-1 = -1/2x -3

y=-1/2x-2

Hence, the equation of the line that passes through the point begin ordered pair, negative 6, 1, end ordered pair and has a slope of begin fraction . . . negative 1 over 2 . . . end fraction is y=-1/2x-2.

What can you conclude from the diagram

Answers

Answer:

You can conclude from the diagram that m∠P is less than m∠N ⇒ A

Step-by-step explanation:

In any triangle, you can arrange the lengths of the sides according to the measure of the opposite anglesIn any triangle, you can arrange the measure of the angles according to the lengths of the opposite sides

Example:

In ΔABC, if the arrangement of the sides is AB < BC < CA, then the arrangement of the measures of the angles is m∠C < m∠A < m∠B

Let us use this fact to solve the question

→ In ΔKNP

∵ KP = 8 units

∵ KN = 6 units

∵ 6 < 8

∴ KN < KP

∵ ∠P is opposite to the side KN

∵ ∠N is opposite to the side KP

∵ KN < KP

→ By using the fact above

∴ m∠P < m∠N

∴ m∠P is less than m∠N

∴ You can conclude from the diagram that m∠P is less than m∠N
