Answer:
B
Step-by-step explanation:
We are given a right triangle with angles 45, 90, and 45
With this type of right triangle, the ratio of the sides are 1:1:square root of 2
We are also given that the hypotenuse is 18
This means that the sides are in the ratio of x:x:x(square root of 2)
Since 18 is the hypotenuse, we can form the equation of-
18 = x(square root of 2)
18/(square root of 2)=x
x= 9 square root of 2
since y=x, y= 9 square root of 2

ABCD is a square
=> Δ ABD is a isosceles right triangle at A
using pythago theorem, we have:
AB² + AD² = BD²
=> 2AD² = 4
⇔ AD² = 2
⇒ AD = √2
through O, draw EF parallel to AD and BC
=> EF is diameter
because EF//AD => EF = AD = √2 (because circle O is inscribed the square ABCD)
=> the area of the circle is [tex]S=\frac{(\sqrt{2})^{2} }{4}.\pi =\frac{\pi }{2}[/tex]
Step-by-step explanation:
the velocity of a falling body varies directly as the time of flight if the velocity of the falling body at the end of two seconds is 64.4ft/s find the velocity at the end of 5 seconds
Answer:
Step-by-step explanation:
If the velocity of a falling body varies directly as the time of flight, this is expressed as;
v α t
v = kt
k = v/t
If at t = 2secs, v = 64.4ft/s
k = 64/2
k = 32 ft
To get the velocity at the end of 5 secs, we will say;
at t = 5secs v = ?
From the formula;
v = kt
v = 32(5)
v = 160ft/s
Hence the required velocity is 160ft/s
x - y = 11 and 2x + y = 19 by elimination
Answer:
(14,3)
Step-by-step explanation:
2x + y = 19
x - y = 11
-2(x - y) = -2(11)
-2x + 2y = -22
-2x + 2y = -22 + 2x + y = 19
3y = -3
y = 3
-------------------------------------------------
x - y = 11
x - 3 = 11
x = 11 + 3
x = 14

Step-by-step explanation:
Options A, C and D are correct.
FACTORIZE
A(X)=(3x-2)^2-(2x-3)^2
Answer:
5(x - 1)(x + 1)
Step-by-step explanation:
A(x) = (3x - 2)² - (2x - 3)² = (3x - 2 + 2x - 3)[3x - 2 - (2x - 3)] = 5(x - 1)(x + 1)
When the equation 16/x = 4 is simplified, the value of x is??
Answer: x=4
Step-by-step explanation:
multiply each side by the denominator to cancel out the fraction so the new equation is 16=4x then divide by 4 to eliminate the x and 16 divided by 4 is 4 which is the anwser.

The perimeter of a triangle is 43 inches. The second side is 4 times as long as the first side. The third side is 1 inch longer than the first side. What is the length of each side
Answer:
First side=7
Second side =28
Third side =8
explanation:
Perimeter of a triangle is the sum of the length of the sides of the triangle. Given that the perimeter of the triangle = 43 inches
Second side is 4 times the first side
Third side is 1 inch longer the first
Let's call the first side x
Then equation for the perimeter of the triangle is given by
x+4x+x+1=43
We solve for x
6x+1=43
6x=43-1
6x=42
x=42/6
x=7
Therefore the first side x=7, the second side is 4x= 4*7=28, third side= 1+x= 1+7=8

Step-by-step explanation:
Answer:
4/9
Step-by-step explanation:
When you go to do a repeating decimal, put whatever repeats over 9. For example lets say we want .49494949 repeating it would be 49/99
however in this case we want 4 to repeat so it would be 4/9.
One factor of f(x) = x3 − 14x2 + 61x − 84 is (x − 7). What are the zeros of the function?
Answer:
-7
Step-by-step explanation:
Because zero is the x, so x=-7 then it's -7
The zeros of the polynomial function is x = 7, x = 3, and x = 4 if one factor of f(x) = x³ − 14x² + 61x − 84 is (x − 7).
What is a polynomial?Polynomial is the combination of variables and constants systematically with "n" number of power in ascending or descending order.
[tex]\rm a_1x+a_2x^2+a_3x^3+a_4x^4..........a_nx^n[/tex]
It is given that:
f(x) = x³ − 14x² + 61x − 84
One factor is (x - 7)
The cubic polynomial can be written as:
f(x) = (x - 7)(x² - 8x + 12)
Or
f(x) = (x - 7)(x - 3)(x - 4)
To find the zeroes equate to zero:
f(x) = 0
(x - 7)(x - 3)(x - 4) = 0
x = 7, x = 3, and x = 4
Thus, the zeros of the polynomial function is x = 7, x = 3, and x = 4 if one factor of f(x) = x³ − 14x² + 61x − 84 is (x − 7).

Two angels of a triangle measure 12 and 40.
What is the measure of the third angle of the triangle ?
Answer:
C) 128
Step-by-step explanation:
Sum of all three angles of triangle = 180
Let the third angle be 'x'
x + 12 + 40 = 180
x + 52 = 180
x = 180 - 52
x = 128

what is the slope of line segment 7 ?
——PLEASEE HELP.!! ILL GIVE BRAINLIEST.!! *EXTRA POINTS* DONT SKIP:((———
Answer:
The slope is 0 because it is a straight line
Step-by-step explanation:
Answer:
undefined.
Step-by-step explanation:
You could be really formal and use the slope formula
The y values are both the same -- 4.
The x values are 3.5 and 6.5
Therefore the slope is (6.5 - 3.5) / (4 - 4)
The denominator is 0
The slope is undefined because 3/0 is not very well behaved.
A horizontal line always gives an undefined amount.
Write the point-slope form of the equation of the line through the point (3,-5) with a slope of -4/3.
Answer:
Step-by-step explanation:

As soon as a new car is purchased and driven away from the dealership, it begins to lose its value, or depreciate. Alonso bought a 1994 Plymouth Neon for $9559. One year later, the value of the car was $8500. What was the percent of decrease of the value of the car?
P.S. This is a percent increase/decrrease
from: 9559
to: 8500
%/100 = differences of to and from/ from ( before the number )
( no negative difference, bigger number subtract smaller number)
Answer:
11%
Step-by-step explanation:
$9559-$8500=1059
1059/9559= .110786
.110786 x 100= 11.0786%
11.0786%= 11%
