Answer:

[tex]y=\sqrt x - 5[/tex]

Step-by-step explanation:

Given:

The range of the function includes the value '-4'.

The range of a function is the output of the function denoted by the variable 'y'. The input of the function is called the domain and is represented by the variable 'x'.

Here, the 'y' value is -4 which is a negative number.

The last two options given represent a square root function. We know that, the output of a square root function is always a positive number. So, for the last two options the range is always greater than or equal to 0. Thus, these two options are eliminated.

Now, if we consider the second option, let us replace 'y' by -4 and solve for 'x'. This gives,

[tex]-4=\sqrt x + 5\\-4-5=\sqrt x\\\sqrt x= -9[/tex]

But, we know that, the result of a square root function is never negative. Therefore, this option is also incorrect.

Hence, only the first function is correct which can verified below.

[tex]y=\sqrt x-5\\-4=\sqrt x-5\\\sqrt x=-4+5\\\sqrt x=1\\x=1[/tex]

So, we got a positive result without violating the definition of square root functions.

Therefore, the correct answer is [tex]y=\sqrt x-5[/tex]

A. is the right answer on edge. 2020

Step-by-step explanation:

Answer:

There are 9 terms, and the common difference is 11.

Step-by-step explanation:

The sum of the first n terms of an arithmetic sequence is:

S = n (a₁ + aₙ) / 2

where a₁ is the first term and aₙ is the last term.

252 = n (-16 + 72) / 2

n = 9

The nth term of an arithmetic sequence is:

aₙ = a₁ + d (n−1)

where d is the common difference.

72 = -16 + d (9−1)

d = 11

There are 9 terms, and the common difference is 11.

To find the number of terms and the common difference of an arithmetic progression, you can use the formulas for the sum of an arithmetic progression and the last term. In this case, there are 10 terms in the AP and the common difference is 8.

The first step is to understand that the sum 'S' of the first 'n' terms of an arithmetic progression (AP) can be given by this formula: S=n/2(2a+(n-1)d). Here 'a' is the first term, 'd' is the common difference, and 'n' is the number of terms.

From the question, we know that S=252, a=-16, and the last term is 72. The last term can be expressed as a+(n-1)d, hence 72=-16+(n-1)d.

Solving these two equations we get n=10, meaning there are 10 terms in the AP, and d=8, the common difference.

/2 and /4 because angle 1 is 90

Complementary angles in Mathematics are two angles that add up to 90 degrees. You determine this by adding the measures of two angles; if the sum is 90, the angles are complementary. An example would be angles of 30 and 60 degrees.

In the field of Mathematics, specifically geometry, complementary angles are two angles that add up to 90 degrees. Without the diagram, it's tricky to provide an accurate pair of complementary angles. Nevertheless, if you have pairs of angles in the diagram, you calculate their sum: if it equals 90 degrees, those angles are complementary. For example, if one angle measures 30 degrees and the other measures 60 degrees, those two angles are complementary because they add up to 90 degrees.

$420.8

Step-by-step explanation:

An employee deposits $400 of their paycheck into an investment account that earns 2.6% interest annually.

We assume that the investment account gives a simple interest against the deposits.

If there is no withdrawals or deposits in the account other than this, then after 2 years the sum in the account will be  

[tex]400(1 + \frac{2.6 \times 2}{100}) = 420.8[/tex] dollars (Answer)

Answer:

The amount in the account after 2 years is $421.04

Step-by-step explanation:

Given as :

The principal deposited into account = p = $400

The rate of interest applied = r = 2.6%

The time period = t = 2 year

Let The amount for 2 years in the account = $A

From Compound Interest method

Amount = Principal × [tex](1+\dfrac{\textrm rate}{100})^{\textrm time}[/tex]

Or, $A = p × [tex](1+\dfrac{\textrm r}{100})^{\textrm t}[/tex]

Or, $A = $400 × [tex](1+\dfrac{\textrm 2.6}{100})^{\textrm 2}[/tex]

Or, $A = $400 × (1.026)²

Or, $A = $400 × 1.0526

∴ A = $ 421.04

So, The amount =  A = $421.04

Hence The amount in the account after 2 years is $421.04 Answer

320 cubes

Step-by-step explanation:

3 1/3 inches = 10/3 inches

There are 10 lengths of 1/3 inch in 10/3 inches.

2 2/3 inches = 8/3 inches

There are 8 lengths of 1/3 inch in 8/3 inches.

1 1/3 inches = 4/3 inches

There are 4 lengths of 1/3 inch in 4/3 inches.

In the 3 1/3 inch by 2 2/3 inch by 1 1/3 inch box, you can place 10 by 8 by 4 cubes measuring 1/3 inch on the side.

10 * 8 * 4 = 320

Answer: 320 cubes

It will take 320 cubes of size 1/3 inch  to fill the box a box with a width of 3 1/3 inches, a length of 2 2/3 inches, and a height of 1 1/3 inches

Volume of a cube of side a inch is [tex]\rm a^3\; inch^3[/tex]

Length of one side of the cube = 1/3 inch

[tex]\rm Volume\; of \; the \; cube = (1/3)^3 = 1/27 \; inch^3[/tex]

[tex]\rm Length\; of \; the \; box = 3 \dfrac{1}{3}\; inches = \dfrac{10}{3}\; inches[/tex]

[tex]\rm Width\; of \; the \; box = 2 \dfrac{2}{3}\; inches = \dfrac{8}{3} \; inches[/tex]

[tex]\rm Height\; of \; the \; box = 1 \dfrac{1}{3}\; inches = \dfrac{4}{3} \; inches[/tex]

[tex]\rm The\; volume \; of \; cuboid\; = \; Length\times Width \times Height\\\\So \; the \; volume \; of\; the\; box = (10/3)\times (8/3) \times (4/3)[/tex]

Let there be n be the number of cubes in the box so

Sum of volumes of n cubes = Volume of the box

[tex]\rm n \times (1/27 ) = (10/3)\times (8/3)\times (4/3)\\n \times (1/27) = 320 /27\\n = \bold{320}[/tex]

So, It will take 320 cubes of size 1/3 inch  to fill the box a box with a width of 3 1/3 inches, a length of 2 2/3 inches, and a height of 1 1/3 inches.

90 = 15 + x

Subtract 15 from both sides to isolate the variable

75 = x

Angle N measures 75 degrees

Answer:

h(n+1) = h(n) - 7

Step-by-step explanation:

Our objective is to write the expression for h(n+1) in terms of h(n) which equals -31 -7(n-1)

So we use the given formula to find what h(n+1) is:

h(n+1) = -31 -7((n+1)-1)

h(n+1) = -31 -7(n+1-1)

we now re-arrange the order of terms inside the parenthesis without combining like terms:

h(n+1) = -31 -7(n-1+1)

and use distributive property to multiply "-7" times the "+1" term and get it extracted from inside the parenthesis:

h(n+1) = -31 -7(n-1) -7

Notice that this way we were able to preserve the form of the term h(n) "-31 -7(n-1)" , and see what is the modification introduced to it when finding the term h(n+1). We now replace "-31 -7(n-1)" by "h(n)" in the above equation:

h(n+1) = -31 -7(n-1) -7

h(n+1) = h(n) - 7

And this is the recursive formula that tells us how to construct the following term of a sequence by knowing the previous one.

Answer: 40%

Step-by-step explanation: To find out what percent of shots Hanley made in the last basketball game, we need to write 14/35 as a percent.

To write a fraction as a percent, first remember that a percent is a ratio of a number to 100. So to write 14/35 as a percent, we need to find a fraction equivalent to 14/35 with a 100 in the denominator. We can do this by setting up a proportion.

So we have [tex]\frac{14}{35} = \frac{n}{100}[/tex]

Now, we can use cross products to find the missing value.

1,400 = 35n

÷35      ÷35   ← divide by 35 on both sides of the equation

   40 = n

This means that Hanley made 40% of his shots last basketball game.

To find the percentage of how many shots Hanley made, we can divide how many shots he made to how many shots he took.

14 ÷ 35 = 0.4

Multiply by 100 to find the percentage.

0.4 * 100% = 40%

Thus, Hanley made 40% of his shots.

Best of Luck!

Answer:

average rate of change of the plane = average speed = [tex]\frac{40}{5} =8\frac{feet}{s}[/tex]

Step-by-step explanation:

we know that

average rate of change of the plane = average speed of the plane

average speed = (change in distance)/(change in time)

since th goes from 15 feet to 55 feet from 2 seconds to 7 seconds

change in time = final time - initial time = 7-2 = 5 seconds.

change in distance = final distance - initial distance

                                = 55-15 = 40 feet.

therefore average speed = [tex]\frac{40}{5} =8\frac{feet}{s}[/tex]

∴ [tex]\frac{1}{4} =\frac{?}{12}[/tex]

Multiply numerator and denominator by 3

[tex]\frac{1\times 3}{4\times 3} = \frac{3}{12}[/tex]

Next solving for another fraction:

[tex]\frac{2}{3} =\frac{?}{12}[/tex]

Multiply numerator and denominator by 4

[tex]\frac{2\times 4}{3\times 4} = \frac{8}{12}[/tex]

∴ We have [tex]\frac{3}{12}\  and \ \frac{8}{12}[/tex] with common denominator.

Answer:

They do not have enough flour for both recipes.

Step-by-step explanation:

Given:

Amount of flour Eliza needs = [tex]2 \frac{1}{3}[/tex] cup

[tex]2 \frac{1}{3}[/tex] can be rewritten as [tex]\frac{7}{3}[/tex]

Amount of flour Eliza needs = [tex]\frac{7}{3}[/tex] cup

Amount of flour Jamie needs = [tex]1 \frac{3}{4}[/tex] cup

[tex]1\frac{3}{4}[/tex] can be rewritten as [tex]\frac{7}{4}[/tex]

Amount of flour Eliza needs = [tex]\frac{7}{4}[/tex] cup

Total Amount of flour they have = 4 cups

We need to find whether  they have enough flour for both recipes.

Total Amount of flour they need is equal to sum of Amount of flour Eliza needs and Amount of flour Jamie needs.

framing in equation form we get;

Total Amount of flour they need = [tex]\frac{7}{3}+\frac{7}{4}[/tex]

Now taking LCM for making the denominator common we get;

Total Amount of flour they need = [tex]\frac{7\times 4}{3\times 4}+\frac{7\times 3}{4\times3} = \frac{28}{12}+\frac{21}{12}= \frac{28+21}{12} = \frac{49}{12} \ cups \ \ \ \ \ OR \ \ \ \ \ 4\frac{1}{12} \ cups[/tex]

Now Since the Total amount of flour they need is [tex]\frac{49}{12} \ cups \ \ \ \ \ OR \ \ \ \ \ 4\frac{1}{12} \ cups[/tex] which greater than Total Amount of flour they have which is 4 cups.

Hence we can say that they do not have enough flour for both recipes.

To determine Jordan's unit rate of swimming, divide the number of laps by the minutes taken. If Jordan swims 2 laps in 4 minutes, the unit rate is 0.5 laps per minute. This concept is widely applicable, enabling comparisons of performance across different contexts.

Jordan can swim 2 laps in a given number of minutes. To find Jordan's unit rate of laps per minute, we would simply divide the number of laps by the number of minutes. For example, if Jordan swims 2 laps in 4 minutes, the unit rate would be 0.5 laps per minute.

To find a unit rate, you always divide the first quantity (number of laps) by the second quantity (time in minutes), ensuring you have a rate reflective of one unit of time. This unit rate can then be used to calculate how many laps Jordan could swim in a different given time frame.

Examples of Unit Rates

Unit rates are beneficial for comparing performance and can apply to various scenarios like estimating how long it would take to fill a swimming pool or determining the velocity of a common garden snail.
