Step-by-step explanation:
The right side of the identity
[tex]cos^{2} x sec^{2} x - cos^{2} x\\= cos^{2} x (\frac{1}{cos^{2} x} ) - cos^{2} x\\= 1 - cos^{2} x\\= sin^{2} x[/tex]
which is the same as the left side of the identity

The rectangle below has an areas of x^2+8x+15 square metres and a width of x+3 meters what expression represents the length of the rectangle
Answer: x+5 or ((x^2+8x+15)/(x+3))
Step-by-step explanation: First let's assign our variables.
x^2+8x+15 = Area
X+3 = Width
? = Length
If the equation of a=lw, then we can substitute in our variables.
a=lw
x^2+8x+15= L (x+3)
Now we must isolate L.
Divide both sides of the equation by 'x+3'
x^2+8x+15= L (x+3)
x+3 x+3
x+5= L

Answer:
x=24
Step-by-step explanation:
Hello There!
Angle E and angle D are supplementary angles meaning that the sum of the two angles equals 180
So we setup an equation
180=2x+12+5x
step 1 combine like terms
5x+2x=7x
now we have
180=7x+12
step 2 subtract 12 from each side
12-12 cancels out
180-12=168
now we have
168=7x
step 3 divide each side by 7
7x/7=x
168/7=24
we're left with~ x=24

Answer:
y = -1/2x + 1Step-by-step explanation:
Slope-intercept form:
y = mx + b, where m - slope, b - y-interceptWe are given two points on the graph:
(0, 1) and (2, 0)The first point gives us the y-intercept:
b = 1Finding the slope using slope formula:
m = (y2 - y1)/(x2 - x1)m = (0 - 1)/(2 - 0) = -1/2The formula of the line:
y = -1/2x + 1At Putt Putt, they offer a special for unlimited mini golf. You decide to go golfing with your friends. After golfing and purchasing lots of food, you end up spending $50. In total you leave Putt Putt with $5. Let s represent the amount of money you started with.

How do you think statistics may at times not say something? How can a well-designed study be used to carefully say everything that is important about a population? Is it possible to do so?
Answer:
While statistics are extremely valuable, they are also notorious for being a means that people use to make false and misleading arguments. Also far too often statistics are obtained by taking a sample from a larger group and assuming the whole group has the same characteristics as the sample.
A sample provides a smaller set of the population for review, that delivers data that is useful to represent the whole population. Surveying a smaller sample, as opposed to the entire population, can save precious time for researchers and offer urgent data.

Answer:
y = 15
y = -10
Step-by-step explanation:
y=-5x
y= -5(-3)
= 5 × 3 = 15
y = 15
y = -5x
y = -5(2)
y = -5 × 2
y = - (5 × 2)
5 × 2 = 10
y = -10

Write an equation of a line with the given slope and y-intercept.
m = 1, b = 4
A. y = –1x + 4
B. y = 4x + 1
C. y = x + 4
D. y = x – 4
Answer:
the answer is C
Step-by-step explanation:
You would take and the y axis would equal x since the m is 1 it would just be x and then since you have the 4 you would just add it to the y=x and then it would be y=x+4

What is the sum of the interior angles of this pentagon?
O 900°
O 360°
O 540
O 180°
Answer:
Step-by-step explanation:
360 + 3*180 = -360 + 540 = 180
For four sides -360 + 180*4 = 360
n-2)*180
For a fifteen sided share the sum of angles = (15-2)*180 = 13*180
Answer:
180
