The inequality that can be used to find the least and greatest temperatures that meet this requirement is D. x − 2 ≥ 85

The least allowable temperature is 83° degrees Fahrenheit.

The greatest allowable temperature is 87 degrees Fahrenheit.

From the information, the fitness center requires its swimming pool to be within 2 degrees of 85 degrees Fahrenheit.

In this case, the inequality that can be used to find the least and greatest temperatures that meet this requirement is D. x − 2 ≥ 85.

The least allowable temperature is:

= 85 - 2

= 83° degrees Fahrenheit.

The greatest allowable temperature is:

= 85 + 2

= 87 degrees Fahrenheit.

Part A: Yes, there is a correlation between the number of hours students spent studying and the score on the music test because  As we increase the hours of studying by 0.5 hours, then the music score increases by 2.

Part B: A function that best fits the data is; y = 60 + 4x

Part C: The slope and y-intercept of the plot indicates that Y is the score obtained in music test and number of hours spent on studying.

We have given the table below showing the data:

Number of hours spent studying (x) 0 0.5 1 1.5 2 2.5 3 3.5 4

Score on music test (y) 60 62 64 66 68 70 72 74 76

A) As we increase the hours of studying by 0.5 hours, then the music score increases by 2.

B) The function which best fits the data for the correlation from the above is; y = 60 + 4x

C) The slope and y-intercept of the plot indicates that Y is the score obtained in music test and number of hours spent on studying.

The slope of the above equation represents the rate of increase in music score with respect to an increase in the number of hours spent on studying.

The y-intercept gives the music score when the number of hours spent on studying is zero.

sin( θ) = 12/13 and tan( θ) = 12/5.

sin θ, cos θ, tan θ are the three important trigonometry functions.

If θ lies in the first quadrant that is 0 ≤ θ < π/2, then the value of all trigonometry functions is positive.

The three most significant trigonometry functions are sin θ, cos θ, and tan θ.

If θ is located in the first quadrant, which is equal to θ/2, then all trigonometric functions have positive values.

The three important trigonometry identities are:

sin²( θ ) + cos²( θ ) = 1

1 + tan²( θ ) = sec²( θ )

1 + cot²( θ ) = csc²( θ )

Now we have,

cos θ = 5/13

Then,

sin²( θ ) + cos²( θ ) = 1

sin²( θ ) + ( 5/13 )² = 1

sin²( θ ) + 25/169 = 1

sin²( θ ) = 1 - 25/169

sin²( θ ) = ( 169 - 25)/ 169

sin²( θ ) = 144/ 169

sin( θ ) = √( 144/ 169 )

sin( θ ) = ± 12/13

Since, 0 ≤ θ < π/2

sin( θ ) = 12/13

Now we know,

tan(θ) = sin(θ) / cos(θ)

tan(θ) = ( 12/13 ) / ( 5/13)

tan(θ) = 12/5

Answer:

5/18

Step-by-step explanation:

1/2 × 9/9 = 9/18

2/9 × 2/2 = 4/18

This means we have 9/18 and 4/18 left in the circle. Because these fractions have a common denominator, we can now subtract them from the whole to find the shaded portion:

18/18 - 9/18 - 4/18 = 5/18

The shaded portion is 5/18, which is already in simplest form.

Given, the sides of the rectangle are:

length = 2x ₊ 2 and

breadth = 3x ₋ 2

perimeter of the rectangle = 48 units

2(l ₊ b) = 48

2(3x ₋ 2 ₊ 2x ₊ 1) = 48

2(5x ₋ 1) = 48

10x ₋ 2 = 48

10x = 48 ₊ 2

10x = 50

x = 50/10

x = 5

therefore, length = 2x ₊ 1 = 2(5) ₊ 1 = 11 and

breadth = 3x ₋ 2 = 3(5) ₋ 5 = 10

hence we get the value of x as 5

The difference between depths in January and July is 14 feets

The depth of a local river averages 16 ft., which is represented as |−16|.

In January,  The depth of a local river measured 4 ft. deep, or |−4|

in July, The depth of a local river  18 ft., or |−18|

The average depth of a local river  is measured as -16 because it is below the ground level and hence measured or plotted on -y axis

the difference between depths in January and July can be measured as

|−18| -  |−4|

This is absolute sign which means every number inside this sign should be treated as positive

The volume of the glass jar is 87.96 cubic inch.

Volume is a unit used to express how much three-dimensional space is occupied. It is usually represented quantitatively in different imperial measures, such as the gallon, quart, and cubic inch, or in SI-derived units like the cubic meter and liter. The cubic concept of length and volume are connected.

Volume is a three-dimensional measurement that's used to gauge a solid shape's capacity. It implies that the volume of a closed form determines how much space it may occupy in three dimensions.

The capacity of the jar is calculated as

Volume of cylinder = [tex]\pi r^{2}h[/tex] = [tex]\pi (2^{2})7[/tex] = [tex]28\pi[/tex] = 87.96 cubic inch.

Hence the capacity of the glass jar is 87.96 cubic inches.
