Answer:
4 sides
Step-by-step explanation:
A lot of math is about pattern matching. Here, you're asked if sides are the same length (one side matches another), if there are right angles (square corners), and if the number of angles or sides is 4.
You might make the observations ...
pink: 2 pairs of parallel sides that are the same length (4 sides). Adjacent sides are different length.
orange: all 4 sides are congruent and at right angles
blue: 2 pairs of parallel sides that are the same length (4 sides). Adjacent sides are different length.
green: 2 pairs of parallel sides that are the same length--4 sides and 4 right angles. Adjacent sides are different length.

The only feature in common is "4 sides."

the function of g(x) is the height of a football x seconds after it is theown in the air. The football reaches its maximum height of 30 feet in 4 seconds, and hits the ground at 10 seconds. What is the practical domain for the function f(x)?
Answers
The domain of the function will be less than or equal to 4 is x ≤ 4
Domain of a functionThe 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

Write the equation of the line that passes through the points (7, –4) and (–1, 3), first in point-slope form, and then in slope-intercept form.
Answers
Answer:
y +4 = -7/8(x -7)y = -7/8x +17/8Step-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

8 and the interest rate on the second loan was 9%.
Answers
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

y = 20ml
x= 60-20 = 40 ml

Inverse Additive

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.

Answers
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°

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)
