Which of these data sets represents a function?

Answer:

77 represents the starting temperature; the temperature after 2 minutes will be 177 degrees

Step-by-step explanation:

77 in Brooklyn's equation represent the oven's temperature after o minutes.

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

Given,

Brooklyn wants to predict the final temperature after 2 minutes.

the equation y = 77 + 50x,

y represents the final temperature in degrees Fahrenheit

We need to find what the number 77 represents in the equation.

77 represents the initial temperature of the oven.

50x represents the change in the temperature of the oven.

Hence,  77 in Brooklyn's equation represent the oven's temperature after o minutes.

Step-by-step explanation:

You take the equations that the exercise give you:

Now you clear the "y" variable in any equation you want, in this case, I'm gonna use the second equation:

   3. y =  x - a

And now, you'll replace this third equation in the equation you didn't take (the first in this case).

Add the x variables:

That's the answer of the exercise, but you can represent this in this form:

17,430g

Step-by-step explanation:

convert kilogram to gram

1kg = 100g

0.83 x 1000 = 830g

7 x 3 = 21 days

total grams used in 3 weeks = 21 x 830 = 17,430g

Answer:

15.833 pints of chalkboard paint

Step-by-step explanation:

Surface area of a rectangular prism = 2(lw × hl × hw)

Where,

L = length = 15 feet

w = Width = 13 feet

h = height = 10 feet

Surface area of a rectangular prism = 2(lw + hl + hw)

= 2(15*13 + 10*15 + 10*13)

= 2(195 + 150 + 130)

= 2(475)

= 950 square feet

One pint of chalkboard paint covers 60 square feet

Least number of pints needed to paint the walls = 950 square feet / 60 square feet

= 15.833 pints of chalkboard paint

and thats -6

hope this helped

good luck

Please read through this carefully. I’d love to help, but I want you to understand why this is the answer and not just copy and paste.

Answer:

1. -6

2. 20

Step-by-step explanation:

1. Simply replace x with 2, since x=2. 2x -3 is the same as -3+-3, which is -6.

2. Simply replace x with 2, since x=2. 2x5 is the same as 5+5, which is 10. 10+10=20, therefore, the answer is 20.

Answer:

124.3 ft

Step-by-step explanation:

We solve the above question using the Trigonometric function of Tangent

= tan θ = Opposite/Adjacent

θ = Angle of Elevation = 73°

Adjacent = 38 ft

Opposite = x

Hence

tan 73° = x/38 ft

Cross Multiply

x = tan 73° × 38 ft

x = 124.2923995 ft

Approximately = 124.3 ft

Therefore, Nick is 124.3 ft from the ground.

Step-by-step explanation:

sin^2(x)= 3 cos^2(x)

Subtract sin^2(x) on both sides

0=3cos^2(x)-sin^2(x)

By Pythagorean Identity sin^2(x)+cos^2(x)=1, we can replace cos^2(x) with 1-sin^2(x)

0=3(1-sin^2(x))-sin^2(x)

Distribute

0=3-3sin^2(x)-sin^2(x)

Combine like terms

0=3-4sin^2(x)

Add 4sin^2(x) on both sides

4sin^2(x)=3

Divide both sides by 4

sin^2(x)=3/4

Take the square root of both sides

sin(x)=+ or - sqrt(3/4)

sin(x)=+ or - sqrt(3)/sqrt(4)

sin(x)=+ or - sqrt(3)/2

This happens on the unit circle at

60 degrees

120 degrees

240 degrees

300 degrees

If we go around and around again forwards or backwards, we get the infinitely many other solutions including the one's already stated in the following solution sets

(60 +360n) degrees

(120 +360n)degrees

(240 +360n)degrees

(300 +360n)degrees

where n is an integer

x is 120 degrees or (120+360n) degrees in the second quadrant. I didn't know if you were just looking for solutions in the first nonnegative cycle of the unit circle or not.

240 degree one or the (240+360n) degrees terminates in the third.

Answer:

Median --> 357.5

Q1 --> 298

Q3 --> 422

IQR > 124

Step-by-step explanation:

3 daily attendance at the water park: 346, 250, 433, 369, 422,298

Find the median, Q1, Q3,and IQR

Step 1

We rearrange the given data set

250, 298, 346, 369, 422, 433

a) The Median

The formula to find the Median

= 1/2( n + 1)th term

Where n = Number of terms = 6

Median = 1/2(6 + 1)th

= 1/2(7)th term

= 3.5th term

The 3.5th term = The number between the 3rd and 4th term

3rd term = 346

4th term = 369

Hence,Median = 346 + 369/2

= 357.5

2) Q1 = First Quartile

= 1/4(n + 1)the

= 1/4( n + 1)th term

Where n = Number of terms = 6

Median = 1/4(6 + 1)th

= 1/4(7)th term

= 1.75th term

The 1.75th term = 2nd term

= 298

Q1 = 298

3) 3/4( n + 1)th term

Where n = Number of terms = 6

Median = 3/4(6 + 1)th

= 3/4(7)th term = 21/4th term

= 5.25th term

The 5.25th term = 6th term

Q3 = 422

4) Interquartile Range = Q3 - Q1

= 422 - 398

= 124

Answer:

+13 was supposed to be -13

Step-by-step explanation:

The value of x for which the trinomial 2x^2−x+55 equal to the square of binomial x+5 is 5 and 6

Given the equation 2x^2−x+55, if the expression is equal to the square of binomial x + 5, then;

2x^2−x+55 = (x+5)^2

2x^2−x+55 = x^2 + 10x + 25

Collect the like terms;

2x^2-x^2-x-10x+55-25 = 0

x^2 - 11x + 30 = 0

Factorize the result

x^2 - 6x - 5x + 30 =0

x(x-6)-5(x-6) = 0

x-5 = 0 and x - 6  = 0

x = 5 and 6

Hence the value of x for which the trinomial 2x^2−x+55 equal to the square of binomial x+5 is 5 and 6

Need to know how many ounces in a scoop of pig food. Is there a ratio or formula associated? Lmk.

Answer:

This answer is 42

Step-by-step explanation:

42 - 24 = 18

Statements are (underlined) and reasons are (bolded).

It is given that (<W) and (<Y) are both right angles, therefore, they must be congruent since they have the same angle measures.

<W = <Y definition of right angles

Moreover, it is given that (VX) and (ZX) are congruent.

VX = ZX given

Finally, it is given that (x) is the midpoint of (WY). Therefore, (WX) is congruent to (XY), and therefore, they are congruent.

WX = XY definition of midpoint

Thus, triangle (YWX) is congruent to (ZYX) by the following rule, side-angle-side, also known as (SAS).

YWX = ZYX SAS

When two sides and an angle are congruent between two or more triangles, then those triangles must be congruent.
