Answer:

Step-by-step explanation:The following statements are true about exponential functions:

-The domain is all real numbers.

- The input to an exponential function is the exponent.

- The base represents the multiplicative rate of change.

The reason why the other two options are wrong are explained below:

The range of exponential functions is not always includes negative numbers; on the contrary, the range is the set of all positive real numbers.

The graph of an exponential function does not have a horizontal asymptote at x = 0; contrarily, the equation of the horizontal asymptote of the graph of is y = 0, which is the x-axis.

There are 5 people with 3 "spots."

      We can use the following formula to solve for the possible ways that they could be photographed. This calls for a "permutation."

-> n is the total number of people, 5

-> r is the sample, 3, we are taking a picture of at a time

n! / (n−r)!

Answer:

3.88 Pints

Step-by-step explanation:

First we need to find the amount of blue paint that was used. We can do that by multiplying 9.7 by 0.60 since that is 3/5 in decimal form

[tex]9.7*0.60=5.82[/tex]

Now we know how much blue paint was used, now we just need to find how much white paint was used. We can do that by subtracting our amount of blue paint from the total amount of paint used

[tex]9.7-5.82=3.88[/tex]

thus, 3.88 is the amount of white paint used

Explanation:

All you do is deduct the people watching giraffes from the total number of people at the zoo:

[tex]\displaystyle \boxed{5} = -7 + 12[/tex]

I am joyous to assist you at any time.

5 people’s are watching the otters …

12 people are watching the otters at the zoo. 7 people are watching the giraffes. How many more people are watching the otters ?

How many more people are watching the otters ?

→ At the zoo, 12 people are watching the otters & 7 people are watching the giraffes...

• So , you have to find how many people’s are watching otters more than the giraffes...

→ Then use , Subtraction to find How many more people are watching the otters..

[tex]12 - 7 = 5[/tex]

• Therefore , 5 people’s are more peoples are watching the otters than the giraffes….

o Quadrant IV is located in the point (2,_3)

Answer:

Quadrant IV

Step-by-step explanation:

Q I = (+,+)

Q II = (-,+)

Q III = (-,-)

Q IV = (+,-)

Given :

To Find :

⠀

Solution :

We know that,

[tex]\qquad{ \bold{ \pmb{2(Length + Breadth ) = Perimeter_{(rectangle)}}}}[/tex]

Let's assume the length of the rectangle as 4x inches. and the width is 3x inches.

⠀

Now, Substituting the given values in the formula :

[tex]\qquad \dashrightarrow{ \sf{2(4x + 3x )= 98}}[/tex]

[tex]\qquad \dashrightarrow{ \sf{2(7x)= 98}}[/tex]

[tex]\qquad \dashrightarrow{ \sf{14x= 98}}[/tex]

[tex]\qquad \dashrightarrow{ \sf{x= \dfrac{98}{14 } }}[/tex]

[tex]\qquad \dashrightarrow{ \bf{x= 7}}[/tex]

Therefore,

[tex]\qquad { \pmb{ \bf{ Length _{(rectangle)} = 4x \: = 4(7) = 28 \: inches}}}\:[/tex]

[tex]\qquad { \pmb{ \bf{ Width _{(rectangle)} = 3x = 3(7) = 21 \: inches}}}\:[/tex]

Answer:

y+3= -6(x+9)

Step-by-step explanation:

Slope is represented as M

Name the numbers in bracket as y1 and x1

You have to use the formula which is:y-y1=m(x-x1)

Then you substitute the numbers into the formula

y--3=-6(x--9)

when two negatives meet the turn to positive

thats how we can conclude that the answer is y+3=-6(x+9)

Answer:

-1

Step-by-step explanation:

The first number indicates the row number and the second number indicates the column number. Therefore B13،That is, the first row and the third column. -1

A matrix is a rectangular array or table of numbers, symbols, or expressions, arranged in rows and columns. -1 is the value of B13.

A matrix is a rectangular array or table of numbers, symbols, or expressions, arranged in rows and columns.

The given matrix is [tex]B=\left[\begin{array}{ccc}2&5&-1\\0&-3&8\end{array}\right][/tex]

We need to find the value of B13.

In B13 the number one represents the row 1 and 3 represents the columns 3.

So the element in B13 position is third element of first row or first element of the third column.

-1 is the third element of first row and first element of the third column

Hence -1 is the B13 of the matrix.

Answer:

22 (I think)

Step-by-step explanation:

The picture is a lil blurry so I'm not sure if I counted the squares right. But basically, you count the squares from one dot to the next. For example, the one on the top that goes in a horizontal line is 6 squares. As for the other two lines, you count from the dot you're starting at and count VERTICALLY until you reach the same line as the point of the triangle. Like with the left side, it starts at point -5, 4 and you'll count how many squares it takes until you reach the same y-axis line as the tip of the triangle. So you should get to -5, -4 for the left side which counts to 8 squares. Same for the other side, also being 8 squares. Then just add it up. 8+8+6=22.

Given that △TPR and △XPZ are similar triangles, the length of the altitude PY is: 24.

Similar triangles have corresponding sides that have the same ratio, i.e. their sides are proportional.

To find PY, we need to know PZ.

Since △TPR ∼ △XPZ, therefore:

TR/XZ = TP/PZ

Substitute

10/20 = 13/PZ

PZ = (13 × 20)/10

PZ = 26

Find PY using Pythagorean theorem:

PY = √(PZ² - YZ²)

PY = √(26² - 10²)

PY = 24

Therefore, given that △TPR and △XPZ are similar triangles, the length of the altitude PY is: 24.

Step-by-step explanation:

General form of geometric progression:  [tex]a_n=ar^{n-1}[/tex]

(where [tex]a[/tex] is the initial term and [tex]r[/tex] is the common ratio)

Given:

[tex]\implies a_n=4\left(\dfrac13\right)^{n-1}[/tex]

Therefore, when n = 7:

[tex]\implies a_7=4\left(\dfrac13\right)^{7-1}[/tex]
