Answer:
x = 4.8
AC = 16.8
Step-by-step explanation:
From the picture attached,
In ΔABE and ΔACD
BE║CD, and the AC and AD are the transversal lines.
∠ABE ≅ ∠ACD [Corresponding angles]
∠AEB ≅ ∠ADC [Corresponding angles]
ΔABE ~ ΔACD [By AA property of similarity of two triangles]
And by the property of similar triangles, corresponding sides of the similar triangles are always proportional.
[tex]\frac{\text{AC}}{\text{AB}}=\frac{\text{AD}}{\text{AE}}[/tex]
[tex]\frac{x+12}{12}=\frac{10+4}{10}[/tex]
[tex]\frac{x+12}{12}=\frac{14}{10}[/tex]
10(x + 12) = 12 × 14
10x + 120 = 168
10x = 168 - 120
x = 4.8
AC = x + 4.8
= 12 + 4.8
= 16.8

Let a = 8i + 2j, b = –3i + j, and c = 2i – 5j, where i and j are unit vectors.
What is 4a + 2b – 9c in terms of i and j?
8i – 35j
8i – 2j
8i + 53j
8i + 55j
Answers
Answer:
D
Step-by-step explanation:
The value of the vector (4a + 2b – 9c) as per scaler multiplication of vector method is 8i + 55j.
What is vector?A vector is a physical quantity that has both magnitude and direction.
What is unit vector?A vector that has magnitude of 1 is called unit vector.
Given, a = 8i + 2j, b = –3i + j, and c = 2i – 5j.
In order to find the value of the vector (4a + 2b – 9c) in terms of i and j, we need to perform scaler multiplication of vector.
Here, i and j are unit vectors.
Therefore: (4a + 2b – 9c)
= 4(8i + 2j) + 2(–3i + j) - 9(2i – 5j)
= (32i + 8j - 6i + 2j - 18i + 45j)
= (8i + 55j)
Therefore, Option(D) is correct answer.

Answer:
The third
I think its the third because everyone added to the left is -2 from the right
Answer:
The answer is A becuase the initial value is what y is when x = 0 and if you see the pattern between 10 and 8 and also 8 and 6 you see the rate of change is -2. Just add 2 to y when x = 1 so 10 + 2 is 12 which gives the answer A.

the length of the floor is 32 m longed than it’s witdth and there is greater than 200 square meters. You will cover the floor completely with tiles. what will be the possible dimension of the floor?
with solution po sana ty pooooo
Answers
Answer:
Step-by-step explanation:
The area of the floor A = Length * Width
Given
A = 200 square meters
If the length of the floor is 32 m longed than it’s width then;
L = 32+W
A = LW
200 = (32+W)W
200 = 32W + W²
W²+32W-200 = 0
W = -32±√32²+800/2
W = -32±42.71/2
W = -32+42.71/2
W = 10.71/2
W = 5.35 m
L = 32+5.35
L = 37.35m
Hence the dimension is 5.35ft by 37.35m

What is the maximum value of 3x + 5y in the feasible region?
(3, 7)

(6, 0)
Answers
Answer:
Minimum value is 18
It occurs at P(6,0)
Step-by-step explanation:
The given objective function is
The vertices of the feasible region are .
We plug in the vertices in to feasible region and evaluate to obtain,
P(0,7) = 3(0) + 5(7)
P(0,7) = 0+35
P(0,7) = 35
P(3,7) = 3(3) + 5(7)
P(3,7) = 9+35
P(3,7) = 44
P(6,3) = 3(6) + 5(3)
P(6,3) = 15+15
P(6,3) = 33
P(6,0) = 3(6) + 5(0)
P(6,0) = 18+0
P(6,0) = 18

A rectangle has a length that is 3 more than twice the width. It's perimeter is 96 inches
Answers
Answer:
L=33in
W=15in
Step-by-step explanation:
Step one:
given
let the width be x
W=x inches
L= 2x+3 inches
perimeter= 96inches
Step two:
Required
the dimensions of the rectangle
The perimeter is
P=2L+2W
96=2(2x+3)+2(x)
open bracket
96=4x+6+2x
collect like terms
96-6=6x
90=6x
divide both sides by 6
x=90/6
x=15 in
The width is 15 in
The length
L=2x+3
L=2(15)+3
L=30+3
L=33in

Answers
Answer:
1) 25 °
Step-by-step explanation:
Two angles are complementary when the measure of the angles between sum up to 90°;
Given;
Angle 1 = a
Angle 2 = b
a = 15 + 2b
Angle a + Angle b = 90°
15 + 2b + b = 90
15 + 3b = 90
3b = 90 - 15
3b = 75
b = 25°

write the slope intercept form of the equation of the line that goes through the point (5,-6) and has a slope of 2
Answers
Answer:
y = 2x - 16
Step-by-step explanation:
Slope-intercept form: y = mx + b
Given:
Slope(m): 2
Point: (5, -6)
To write the equation in slope-intercept form we need to find the slope(m) and the y-intercept(b).
Since we were given the value of the slope, the only thing we have to do is find the y-intercept. To do this, input the values of the slope and the given point into the equation and solve for b:
y = mx + b
-6 = 2(5) + b
-6 = 10 + b
-16 = b
The y-intercept is -16.
Now that we know the slope and the y-intercept, we can write the equation:
y = 2x - 16

32. The length of a rectangle measures six more than the width. The perimeter of the rectangle is 38.
What are the dimensions of the rectangle?
Answers
Answer: 12.5
You start with the equations "2x +2y=38" and "6+x=y". By adding and subtracting in the second equation, you get "2x +2y=38" and "x-y=-6". When you multiply the second equation by 2, you get "2x-2y=-12."
subtracting the equations "2x +2y=38" and "2x-2y=-12" gets you to "4y=50", where you have to divide two sides by 4 and get "y=12.5"
