The domain of the function will be less than or equal to 4 is x ≤ 4

The domain of a function are real values for which the function exists

For the question given, the time taken will serve as the domain of the function while the height after a particular time will be the range.

The domain depends on the time it takes to reach the maximum height. SInce the football reaches its maximum height of 30 feet in 4 seconds, hence the domain of the function will be less than or equal to 4 is x ≤ 4

Answer: 61

Step-by-step explanation: 1+12*5

Simplify the sum 43+(96/8)*5-42

1

Add 43 and -42

12*5

Reduce 96/8 by factoring out and cancelling common factors

8*12/8.1

Factor out 8 from the top and bottom of the fraction

8*12=96

8*1=8

96/8=12

multiply 12 and 5. 12*5= 60

add 60 and 1

so the answer is 61

answer:

67.5

Explanation:

Let the triangle be ΔABC and angles be ∠A,∠B,∠C

Now, we know that all the 3 angles of a triangle sum up to be 180° from the Triangle Sum Property.

:.∠A + ∠B + ∠C = 180

:.3x+3x+2x=180 [3:3:2]

:.8x = 180

:.x = 180/8

:.x = 22.5°

:.

/_A=3x=3(22.5)=67.5°

/_B=3x=3(22.5)=67.5°

/_C=2x=2(22.5)=45°

Answer:

Let x = ml of 21% solution

Let y = ml of 15% solution

ATQ,

x + y = 60.....(1)

or

0.21x + 0.15y = 0.6....(2)

Multiplying equation 1st by 0.21, we get,

0.21y+0.21y =12.6....(3)

subtracting equation 3

0.21y+0.21y =12.6

-0.21x +0.15y = 0.6

_________________

ㅤㅤㅤ 0.6y = 12

_________________

6y = 12

y = 20ml

x= 60-20 = 40 ml

Hence , Conner needs 20ml of 21% solution & 40ml of 15% solution

2nd statement

Step-by-step explanation:

it is

Explanation:

In the right triangle shown in the attachment, we have, by definition, ...

  sin(θ) = a/c

  cos(θ) = b/c

Then ...

  sin²(θ) +cos²(θ) = (a/c)² +(b/c)² = (a² +b²)/c²

By the Pythagorean theorem, ...

  c² = a² +b²

Substituting for c², we have ...

  sin²(θ) +cos²(θ) = (a² +b²)/(a² +b²)

  sin²(θ) +cos²(θ) = 1

Answer:

12.5

Step-by-step explanation:

In this problem, we see a 5 on one side. The other side will be 5 as they have the congruent line indicator.

The formula for these types of problems are a*b=c*d.

a = 5

b = 5

c =2

d = x

(5)(5)=2(x)

x = 25/2 = 12.5

Answer:

Step-by-step explanation:

Given two points, the equation for the line can be found by starting with determining the slope. Then the point-slope form can be used to find the equation. That form can be rearranged to give the slope-intercept form (or any other form you may desire.)

The slope formula is ...

  m = (y2 -y1)/(x2 -x1)

  m = (3 -(-4))/(-1 -7) = 7/-8 = -7/8

Then the point-slope form using the first point is ...

  y -k = m(x -h) . . . . line with slope m through point (h, k)

  y +4 = -7/8(x -7) . . . . . line with slope -7/8 through (7, -4)

__

Eliminating parentheses, and subtracting 4 gives the slope-intercept equation:

  y +4 = -7/8x +49/8 . . . eliminate parentheses

  y = -7/8x +17/8 . . . . . subtract 4; slope-intercept equation

Answer:

Inverse Additive

Inverse multiplicative

Opposite Numbers

Reciprocal Numbers

Absolute value

Step-by-step explanation:

Inverse Additive is the number that is added to a given number to make the sum zero. For example, the additive inverse of 3 would be -3, because 3 + -3 = 0.

Inverse multiplicative is defined as a number which when multiplied by the original number gives the product as 1. For example, the multiplicative inverse of 5 would be 1/5, because multiplying 1/5 by the number 5 would equal to the product of 1.

Opposite Numbers- The opposite of a number is the number on the other side of 0 number line, and the same distance from 0. Basically same thing as an additive inverse. The negative version of a positive number, and vice versa.

Reciprocal Numbers- The reciprocal of a number is this fraction flipped upside down. In other words, the reciprocal has the original fraction's bottom number—or denominator—on top and the top number—or numerator—on the bottom.

Absolute value- The absolute value (or modulus) | x | of a real number x is the non-negative value of x without regard to its sign.
