Answer:
y - 14(x) = 40 (Hopefully)
Step-by-step explanation:

y = 14(x) + 40
y - 14(x) = 40
If sin²∅ + sin∅ = 1 , then what is the value of sin²∅ + sin⁴∅.
Answer:
Step-by-step explanation:
Given sin²∅ + sin∅ = 1, we are to find the value of sin²∅ + sin⁴∅. ... 2
From sin²∅ + sin∅. = 1; sin²∅ = 1 - sin∅. ... 3
Substitute equation 3 into 1
sin²∅ + sin⁴∅
= sin²∅ + (sin²∅)²
= (1 - sin∅)+( 1 - sin∅)²
open the parenthesis
= 1 - sin∅+ (1-2sin∅+ sin²∅)
= 1 - sin∅+ 1-2sin∅+ sin²∅
= 1+1-sin∅-2sin∅+sin²∅
= 2 - 3sin∅+sin²∅
Since sin²∅ = 1 - sin∅, the resulting equation becomes;
= 2 - 3sin∅+(1 - sin∅)
= 2 - 3sin∅+1-sin∅
= 3-4sin∅

A new youth center is being built in erie . The perimeter of the rectangular playing field is 296 yards. The length of the field is 2 yards less than double the width. What are the dimensions of the playing field?
Answer:
The dimensions are 50 yards by 98 yards
Step-by-step explanation:
If the width is w, then the length is 2w - 2. Perimeter can be expressed by 2 * (length + width), therefore:
2 * (2w - 2 + w) = 296
2 * (3w - 2) = 296
3w - 2 = 148
3w = 150
w = 50 so 2w - 2 = 2 * 50 - 2 = 98
Answer:
[tex]\Large \boxed{\mathrm{98 \ yards \cdot 50 \ yards}}[/tex]
Step-by-step explanation:
Let the length be l.
Let the width be w.
[tex]l = 2w - 2[/tex]
The perimeter of the rectangle is 296 yards.
[tex]P = 2l + 2w[/tex]
Plug in the value for l and P.
[tex]296 = 2(2w-2) + 2w[/tex]
Evaluate and solve for w.
[tex]296 = 4w - 4 + 2w \\\\296 = 6w - 4 \\\\300 = 6w \\\\50 = w[/tex]
The width is 50 yards.
Let w = 50 for l.
Evaluate and solve for l.
[tex]l = 2(50) - 2 \\ \\ l = 100 - 2 \\\\l = 98[/tex]
The length is 98 yards.

using the Pythagoras rule. A rectangular hockey field is 50m long and 35m wide calculate the length of it's diagonal
Answer:
[tex]\huge\boxed{The\ length\ of\ Diagonal = 61 \ m}[/tex]
Step-by-step explanation:
Length = 50 m
Width = 35 m
Using Pythagorean Theorem:
[tex]c^2 = a^2 + b^2[/tex]
Where c = diagonal , a = length (50 m) and b = width (35 m)
=> [tex]c^2 = 50^2+35^2[/tex]
=> [tex]c^2 = 2500 + 1225[/tex]
=> [tex]c^2 = 3725[/tex]
Taking sqrt on both sides
=> c = 61 m
The length of Diagonal = 61 m.
Step-by-step explanation:
a squared +b squared= c squared
where c is the hypotenuse
35^2+50^2=c^2
1225+2500=c^2
3725=c^2
c^2=61.0328
A linear function is defined by the equation 3x - 2y = 6
what is the x and y intercept
Answer:
X intercept = (2,0)
Y intercept = (0,-3)
Step-by-step explanation:
To find x intercept make y into 0
3(x) - 2(0) =6
3x = 6
x = 2
X intercept = (2,0)
Y intercept do the same
Y intercept make x into 0
3(0) - 2(y) =6
-2y = 6
y = -3
Y intercept = (0,-3)
Answer:
x -intercept is at (2, 0).
y -intercept is at (0, -3).
Step-by-step explanation:
x intercept is found when y = 0:
3x - 2(0) = 6
3x = 6
x = 2.
x intercept is found when x = 0:
3(0) - 2y = 6
-2y = 6
y = -3.

If h hot dogs cost d dollars, what is the cost, in cents, of j hot dogs?
Answer:
jd/h dollars.
Step-by-step explanation:
h hot dogs cost d dollars , therefore:
1 hot dog costs d/h dollars
- and j hot dogs cost j * d/h dollars.
Answer:
100dj/h cents.
Step-by-step explanation:
If h hot dogs is d dollars, then 1 hot dog should be:
d/h
To find the cost of j hot dogs:
d/h × j = dj/h dollars
To turn dj/h dollars into cents:
1 dollar = 100 cents
dj/h dollars = ?
dj/h × 100
= 100dj/h cents

Step-by-step explanation:
A 90° CCW transformation is ...
(x, y) ⇒ (-y, x)
For A(5, -2), the image point is A'(2, 5).
_____
In your mind, draw a line segment from the origin to point A. You will see that is slope is (rise)/(run) = -2/5.
When you rotate that segment 90° CCW about the origin, it will extend into the first quadrant. The rotated segment is perpendicular to the one you started with, so its slope is ...
-1/(-2/5) = 5/2
That is, it will have a rise of 5 for a run of 2. The point A' will have a x-coordinate of 2 (the run), and a y-coordinate of 5 (the rise).
A'(2, 5)
What is 1/2 of a right angle called
Answer:
acute angle
Step-by-step explanation:
acute = less than 90 degrees
right = exactly 90 degrees
obtuse = more than 90 degrees
90 divided by 2 = 45
45 is less than 90 so acute angle
1/2 of a right angle is called an acute angle. The correct answer would be an option (D).
What are the vertical angles?When two lines intersect at a location, vertical angles are generated. They are always equal to each other.
An angle with a measure of 1/2(90°) : 45°
As per the given question, the required solution would be as:
Straight: An angle with a measure of exactly 180° is considered straight. 45° is not a straight angle.
Obtuse: An angle with a measure greater than 90° and less than 180° is considered obtuse. 45° is not an obtuse angle.
Acute: An angle with a measure less than 90° is considered acute. 45° is an acute angle.
Thus, 1/2 of a right angle is called an acute angle.

Step-by-step explanation:
( a ) The value 1200 in this content represents the starting value, or the number of bacteria that was present in the beginning.
( b ) 1.8 represents the growth factor, or by how much more the bacteria increases, in multiples of the quantity.
( c ) As you can tell 1000 has a similar function as 1200, it models the number of bacteria present in the beginning. The difference between the studies is that the second study is present with a starting value of 1000 yet a similar growth factor, and hence will always have a smaller number of bacteria after t hours.
the expression 7x + 300 represents the amount of interest that is being paid for a new tv in dollars, where x is months. what does 7x represent, and is it a term, factor, or coefficient
Answer:
7x means that you are paying for 7 months. and 7x is a term.
Step-by-step explanation:
Rules for whether its a term, coefficient, or factor:
a TERM has a variable. 7x is a term.
a COEFFICIENT is the number part of a term. in 7x, the coefficient is 7.
a FACTOR is something which is multiplied by something else. A factor can be a number, variable, term, or a longer expression.
if AB ll CD , EF ll BC, angle bac = 65 and angle dhf = 35 find angle agh
Answer: 100
Step-by-step explanation:
You know that AB is || to CD, angle BAC ≅ ACD (this is the theorem where a line connecting the diagnose of two parallel line, the alternative interior angles are equal/ congruent)
You know that EF is || to BC, angle DHF ≅ GHC (these two are vertically opposite angle which are equal/ this is a theorem)
-------------------------------------------------------------------------
we now know the angles in ΔGHC where angle GHC=35, angle GCH=65, and angle CGH=80 (subtract other angles from 180)
angle AGH is supplementary w=angle with CGH, which means we subtract 80 from 180, we get 100 will be the angle of AGH
