Finda + b, 8a + 9b, |a|, and |a − b|.(Simplify your answer completely.)a =leftangle0.gif−3, 4rightangle0.gifb =leftangle0.gif9,
alekssr [168]

Answer:

Step-by-step explanation:

Given the following vectors a = (-3,4) and b = (9, -1)

|a| and |b| are the modulus of a and b respectively.

|a| = √(-3)²+4²

|a| = √9+16

|a| = √25

|a| = 5

Similarly;

|b| = √(9)²+1²

|b| = √81+1

|b| = √82

We are to find the following;

a) a + b

a+b =  (-3,4)  +  (9, -1)

a+b = (-3+9, 4+(-1))

a+b = (6, 4-1)

a+b = (6,3)

b) 8a + 9b

8a + 9b = 8(-3,4)  + 9(9, -1)

8a + 9b = (-24,32)  + (81, -9)

8a + 9b = (-24+81, 32+(-9))

8a + 9b = (57, 32-9)

8a + 9b = (57, 23)

c) |a| = √(-3)²+4²

|a| = √9+16

|a| = √25

|a| = 5

d)  |a − b|

To get  |a − b|, we need to get a-b first

Solve for a -b

a-b =  (-3,4)  -  (9, -1)

a-b = (-3-9, 4-(-1))

a-b = (-12, 4+1)

a-b = (-12,5)

Find modulus of a-b i.e   |a − b|,

|a − b| = √(-12)²+5²

|a − b| = √144+25

|a − b| =√169

|a − b| = 13

Write down the turning point of the graph y=x^2 - 8x + 22
Sloan [31]

Answer:

y=6

Step-by-step explanation:

Differentiate the equation

dy/dx=2x-8

Find the value of x in equation form

2x-8=0

x=8/2=4

Now x=4 is the line of symmetry or the parabola of the quadratic equation.

Plug back x=4 into the equation to find the turning point(minimum value)

y=(4)²-8(4)+22

y=16-32+22

y=6

While on vacation in Canada, you notice that temperatures are reported in degrees Celsius. You know there is a linear
sashaice [31]

Since , the relation is linear .

Let equation is y = mx + c .

Putting , x = 0 and y = 32 .

32 = c  .......( 1 )

Also , putting x = 100 and y = 212 .

We get :

212 = 100m + c .......( 2 )

Comparing equation 1 and 2 .

100m = 212 - 32

x = 1.8

Therefore , y = 1.8x + 32 .

Hence , this is the required solution .

Find the slope of the line give these two points: (0,5) and (-7, -8) *
PSYCHO15rus [73]

Answer:

m=13/7

Step-by-step explanation:

the equation for slope (m) is (y2-y1)/(x2-x1)

the given points are (0,5) and (-7,-8)

we can label them:

x1=0

y1=5

x2=-7

y2=-8

now substitute into the equation

m=(-8-5)/(-7-0)

m=-13/-7

m=13/7

the slope is 13/7

hope this helps!
