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
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.

Two angles are complementary. The measure of one angle is 15 ° more than twice the other. What is the measure of the smaller angle? 1) 25 ° 2) 35 ° 3) 55 ° 4) 65 °
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°

Answer:
The point in the middle at (0,0) is the origin. The line that goes up and down is the y-axis. The lign that goes left to right is the x axis. The y intercept is at (0,-5). The x intercept is at (6,0).
Step-by-step explanation:
The answer is attached.
What are intercepts?The point where the line or curve crosses the axis of the graph is called intercept.
xy-axes:- The x and y-axis are two important lines of the coordinate plane. The x-axis is a horizontal number line and the y-axis is a vertical number line.
xy-intercepts:-
If a point crosses the x-axis, then it is called the x-intercept. If a point crosses the y-axis, then it is called the y-intercept.

A rectangle has a length that is 3 more than twice the width. It's perimeter is 96 inches
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
Answer:
2 (w) + 2(2w + 3) = 96

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
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 slope and the y-intercept of the graph of the linear function shown on the grid ?
Answer:
Slope: -1/4; Y-Intercept: 1.5
Step-by-step explanation:
Step 1: Find the slope. The best way to do this is to transform the two given points to y=mx+b form. When given two points, the best way to find the slope will be to do y2-y1/x2-x1. In this equation it would be -2-0/2+6, which is -2/8, simplified is -0.25 or -1/4. So we have the slope, which can determine the length of the line.
Step 2: Find the Y-Intercept. Finding the Y-intercept is so much simpler when given a graph, since all you have to do is find where the line goes through the y-axis, which in this case is (0,1.5), meaning that the y-intercept is 1.5 (note: the y-intercept can also be found when x=0, for example (0,9).

What is the maximum value of 3x + 5y in the feasible region?
(3, 7)
(0,7)
(6, 3)
(6, 0)
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
Solve for the variables
Answer:
P = 32
x = 35
Step-by-step explanation:
For the first diagram,
The two angles given are corresponding angles. Corresponding angles are equal;
So;
the first angle is a right angle triangle;
90 = 3P - 6
3P = 90 + 6
3P = 96
P = 32
For the second diagram;
The sum of those two angles is 180°
(x + 75) + 2x = 180
x + 2x + 75 = 180
3x + 75 = 180
3x = 180 - 75
3x = 105
x = 35
write the slope intercept form of the equation of the line that goes through the point (5,-6) and has a slope of 2
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
