Find the area and perimeter of the shaded region. Stuck on this one can someone help me
Answers
Answer:
perimeter-
perimeter outer rectangle = 2 (l+b)
=2×8+9
= 2×17
2×17 =34 cm sq.
perimeter of inner rectangle = 2 (l+b)
= 2×5+3
=2× 8
= 16 cm sq.
perimeter of shaded portion= 34 - 16
= 18 cm sq.
area-
area of inner rectangle =l×b
l×b = 3×5
3×5=15
15 cm sq.
area of outer rectangle =l×b
l×b= 9×8
9×8= 72
72 cm sq.
area of shaded portion = 72 -15 =57 cm sq.
hey there! In second method i have done first area of inner rectangle but you have to do first area of outer rectangle...
hope it helps you....
Answer:
Let A1 = be the large rectangle and A2 the small rectangle
=> Area A1: S1 = a1.b1 => S1 = 8 x 9 = 72m2
=> Area A2: S2 = a2.b2 => S2 = 3 x 5 = 15 m2
=> Area of the remaining surrounding square: S1-S2 = 72-15 = 67m2
=> Perimeter A1: P1 = 2 (a1 + b1) = 2 (9 + 8) = 34m
=> Perimeter A2: P2 = 2 (a2 + b2) = 2 (3 + 5) = 16m
=> Perimeter of the surrounding square: P1-P2 = 34-16 = 18m

Answers
one of the trigonometry rules is sin^2(x) + cos^2(x) = 1 if you rearrange this you realize that sin^2= 1-cos^2(x)
we also know that csc^2(x)= 1/sin^2(x) so now you can rewrite your equation as:
sin^2(x) x 1/sin^2(x) = 1
sin^2(x)/sin^2(x) =1
the LHS (left hand side) can cancel down to 1 because the numerator and denominator are the same
so then 1=1 Therefore LHS=RHS

These "special" right triangles have side length ratios that it is useful to remember.
45°-45°-90° triangle
Sides have the ratios 1 : 1 : √2. That is, x is √2 times as long as the side length shown as 18.
x = 18√2

That is, y is √3 times the length of the side marked 18, and z is 2 times the length of the side marked 18.
y = 18√3

$213 ski jacket with a 30% discount and a 6% tax
Answers
Take the discount off first, 213*.70=149.10, then multiply 149.10*1.06= $158.046
158.04$.
What is discount?A discount is a decrease in the cost of a commodity or service. If the item is broken, you can ask the manager for a discount.
Given the Written price of the ski jacket is 213$ on that there is a discount of 30% and 6% of tax. Hence,
discounted price of jacket = 213 (1- 30%)
discounted price of jacket = 149 approx.
Total price of the jacket after-tax = 149 (1 + 6%)
The total price of the jacket after-tax = 158.04$
Therefore, the price of a $213 ski jacket with a 30% discount and a 6% tax is 158.04$.

If a certain cannon is fired from a height of 9.8 meters above the ground, at a certain angle, the height of the cannonball above the ground, h, in meters, at time, t, in seconds, is found by the function h(t) = -4.9t² + 30.5t +9.8. Find the time it takes for the cannonball to strike the ground.
Answers
Answer:
6.53 s
Step-by-step explanation:
The height of the cannon ball is represented by a quadratic function as:
h(t) = -4.9t² + 30.5t +9.8.
At 0 s (i.e. t = 0), h(0) = -4.9(0²) + 30.5(0) + 9.8 = 9.8
That means that the cannon ball is initially at a height of 9.8 m above the ground. To calculate the time it takes the ball to touch the ground, we use:
h(t) = -4.9t² + 30.5t +9.8
It touches the ground when h(t) = 0. Hence:
0 = -4.9t² + 30.5t + 9.8
Solving the above quadratic equation gives:
t = 6.53 s and t = -0.31 s
Since the time cannot be negative, hence t = 6.53 s. Therefore it takes the ball 6.53 s to hit the ground.

What is Translation of Functions?Translation of functions is defined as the when each point in the original graph is moved by a fixed units in the same direction.
There are horizontal translation and vertical translation of functions.
Given is a function f(x).
f(x) = x²
A horizontal translation makes the function f(x) to f(x ± k), where k is the unit of translation.
And the vertical translation results in f(x) = f(x) ± k.
Here function f(x) = x² has been translated 9 units up.
f(x) → f(x) + 9 = x² + 9
Then it is translated 4 units to the right,
g(x) = (x - 4)² + 9, since the translation is towards right.
Hence the correct answer is g(x) = (x - 4)² + 9.

On a coordinate plane, a line goes through (negative 8, 4) and (8, 4). A point is at (negative 4, negative 6).
What is the equation of the line that is parallel to the given line and passes through the point (−4,−6 )?
x = −6
x = −4
y = −6
y = −4
Answers
Answer:
The equation of parallel line passes through the point (−4,−6 ) is:
y = -6
Please also check the attached graph.
Step-by-step explanation:
The slope-intercept form of the line equation
y = mx+b
where
m is the slopeb is the y-interceptGiven that on a coordinate plane passes through (-8, 4) and (8, 4).
As the value of y remains the same for any value of x.
i.e. y = 4 for any value of x.
Thus, the given line is a horizontal line.
We know that the slope of a horizontal line is zero.
Also it is clear that at x = 0, the value of y = 4. In other words, we can observe that the y-intercept b = 4.
so substitutig m = 0 and b = 4 in the slope-intercept form
y = mx + b
y = 0x + 4
y = 4
Therefore, the equation of line passing through the point (-8, 4) and (8, 4) is:
y = 4
Now, we also know that the slope of parallel lines is equal.
Thus, the slope of the line parallel to the line y = 4 is also 0.
As the parallel line passes through (−4,−6 ).
so substituting m = 0 and (-4, -6) in the slope-intercept form of line equation to determine the y-intercept b
y = mx + b
(-6) = 0(-4) + b
-6 = 0 + b
switching the sides
0 + b = -6
b = -6
Thus, the slope-intercept b = -6
now substituting m = 0 and b = -6 in the slope-intercept form of line equation
y = mx + b
y = 0(x) + -6
y = 0 - 6
y = -6
Therefore, the equation of parallel line passes through the point (−4,−6 ) is:
y = -6
