What could be inferred?

A. The flock ate berries from a different fleld.

B. The flock migrated south

C. The flock was scared away by the eagle calls.

D. The flock may have wanted to share the berries with the eagles.

E. The flock Is afraid of all loud animal calls.​

f(x) = 2(x - 3) + 4

For finding f(-8) just substitute the value of x as -8

f(-8) = 2{(-8) - 3} + 4

= 2{-11} + 4

= -22 + 4

= -18

Answer:

-18

Step-by-step explanation:

substitute x with -8

The quotient of two expressions is the division of the expressions

The quotient of [tex]\frac{7^{-1}}{7^{-2}}[/tex] is 7

The expression is given as:

[tex]\frac{7^{-1}}{7^{-2}}[/tex]

Rewrite the above expression by applying the law of indices

[tex]7^{-1 + 2[/tex]

Simplify the exponent

[tex]7^{1[/tex]

Answer:

C 13

Step-by-step explanation:

2 right-angled triangles. so, Pythagoras applies for both.

c² = a² + b²

with c being the Hypotenuse (the side opposite of the 90° angle).

starting with the small triangle we have

5² = 3² + x-part²

x-part² = 5² - 3² = 25 - 9 = 16

x-part = 4 cm

the markers indicate that x-part as the third side of the small triangle is exactly as long as the other part of x.

that means

x = 2 × x-part = 2 × 4 = 8 cm

for the large triangle we then get

y² = x² + 15² = 8² + 225 = 64 + 225 = 289

y = 17 cm

and so,

y - x = 17 - 8 = 9

but that is not an answer option.

and now it dawned on me : x was not meant to be the whole third side of the large triangle. x is supposed to be only the upper part of that side, above the small triangle.

in essence, x is what I originally called "x-part".

so, the Pythagoras calculations remain basically the same, but we should name things differently like

5² = 3² + small-side²

small-side = 4 cm

x = small-side = 4 cm

long-side = 2 × small-side = 2 × 4 = 8 cm

y² = long-side² + 15² = 8² + 15² = 64 + 225 = 289

y = 17 cm

and the actual y - x = 17 - 4 = 13 cm

Length of board will be 32 1/2 inch.

What is Addition?

A process of combining two or more numbers is called addition.

Given that;

Length of board after cutting are;

7 1/2 inches, 10 1/2 inches, 9 inches, and 5 1/2 inches.

Now, Total length of board is calculated as sum of all cut lengths.

So, Total length of board = 7 1/2 +10 1/2 + 9 + 5 1/2

                                      = 15/2 + 21/2 + 9 + 11/2

                                      = 47/2 + 9

                                      = 65/2

                                      = 32 1/2

Thus, Length of board will be 32 1/2 inch.

Answer as a compound inequality: [tex]-4 \le y < 2[/tex]

Answer in interval notation:  [-4, 2)

=============================================

Explanation:

The range is the set of all possible y outputs of a function. When dealing with a graph like this, we just look at the highest and lowest points to determine which y values are possible.

The lowest point occurs when y = -4. We include this value. So far we have [tex]y \ge -4[/tex] which is the same as [tex]-4 \le y[/tex]

The upper ceiling for the y value is y = 2. We can't actually reach this value because of the open hole at (-3,2). So we say that [tex]y < 2[/tex]

Combine [tex]-4 \le y[/tex] and [tex]y < 2[/tex] to get the compound inequality [tex]-4 \le y < 2[/tex]

This says y is between -4 and 2, including -4 but excluding 2.

To convert this to interval notation, we write [-4, 2) where the square bracket says to include the endpoint and the curved parenthesis says to exclude the endpoint.

Step-by-step explanation:

Area (shaded) = Area (rectangle) - Area(triangle)

= (17 x 16) - 1/2(16 x 8)

= 16 (17 - 4)

= 16 (13)

= 208 square feet

Answer:

HOPE THIS HELPS

Step-by-step explanation:

You need to first plot the points on the graph.

Since, it says you need to reflect across x axis, you need same number of square units.

For example, P has the coordinates( -2,3 ). -2 lies on the x axis, so the point doesn't go neither left nor right. It is 3 squares above the x axis, so the reflected point should be 3 squares below the x axis. Likewise, you can do the other points.

A simple algebra equation!

You have to replace each x with 4, so the equation would look like this:

-4·4+1.5·4-2.5-2·4-6.5

Evaluate the terms, you get:

-16+6-2.5-8-6.5

Then you add and subtract where needed:

-10-16 = -27

And that's the final answer!

ANSWER: 27

Step 1 - Find Whole Number

Calculate out how many times the denominator goes into the numerator. To do that, divide 6 by 5 and keep only what is to the left of the decimal point:

6 / 5 = 1.2000 = 1

Step 2 - Find New Numerator

the answer from Step 1 by the denominator and deduct that from the original numerator.

6 - (5 x 1) = 1

Step 3 - Get Solution

Keep the original denominator and use the answers from Step 1 and Step 2 to get the answer. 6/5 as a mixed number is:

Answer:

A

Step-by-step explanation:

We have the graph of the function f(x).

We want to determine which of the given is true of the graph from [tex]x=g[/tex] to [tex]x=\infty[/tex].

So, essentially, we are focusing on the last curve (see image below).

First, since the curve is above the x-axis, the curve is positive.

Second, since the curve is curving upwards, this means that it must be increasing. Another way to think about this is to think about the slope of our curve. While we can't calculate the exact slope, the average slope will be positive, so our function is increasing.

So, our answer is A.

And we're done!

===========================================================

Explanation:

Add up the numbers in the second column:

4+19+25+32 = 80

There are 80 people being surveyed in the table.

Of those 80 people surveyed, 32 of them exercised for more than 136 minutes.

The probability of selecting someone who exercised for more than 136 minutes is the fraction 32/80 = (16*2)/(16*5) = 2/5

----------

Multiply this probability with the larger sample size of 300 to get

(2/5)*300 = 0.4*300 = 120

We estimate that 120 people would exercise for more than 136 minutes.

Note that 120/300 = 2/5.
