Answer:

4v - 7w = (101 , -36)

6u -8v = (-78 , 58)

2u +v - 4w = (40 , -4)

11u + 3w = (-88 , 89).

Step-by-step explanation:

u(-5, 7) ; v(6 , -2) ; w(-11,4)

4v - 7w = (4*6+[-7]*[-11] , 4*[-2] + [-7]*4)

=(24+77 , -6 - 28)

4v - 7w = (101 , -36)

6u - 8v = (6*[-5]+[-8]*6 , 6*7+[-8]*[-2] )

= (-30-48 , 42+16)

6u -8v = (-78 , 58)

2u + v - 4w = (-10+6+44 , 14 -2 -16)

2u +v - 4w = (40 , -4)

11u + 3w = (11*[-5]+3*[-11] , 7*11 +3*4)

= (-55-33 , 77+12)

11u + 3w = (-88 , 89)

Alex787 [66]

16 cm - 2.5 cm = 13.5 cm, which is 1/4 of the diameter of the large gear. Take 13.5 cm * 4, and you have the diameter of the large gear, which is 54 cm.

What is cosA for this triangle? 48/55 55/73 55/48 48/73

mash [69]

For this case we must indicate the cosine of A, of the figure shown. By definition:

$Cosine (A) = \frac {Cateto\ adjacent\ to\ the \ angle} {hypotenuse}$

Substituting the values we have:

$Cosine (A) = \frac {48} {73}$

So, we have to:

$Cosine (A) = \frac {48} {73}$

Solve for x. Round to the nearest tenth, if necessary.

pychu [463]

Answer:

x = 14

Step-by-step explanation.

First I would use sine to find x's value. So ----> sin(30) = 7/x ----> x sin(30) = 7 ----> x = 7/sin(30) = 14.

You Can also find that x is equal to 14 by applying the 30, 60, 90, triangle rule. Becuase '7' opposes the 30 degree angle it is 1/2 the hypotenuse, if thats the case just multiply the 7 by 2 and you have the hypotenuse length.

If AM = x + 8 and MB= 6x – 2, find MB.

IrinaK [193]

Answer:

Step-by-step explanation:

Firstly, AM=x+8

or, A=x+8-M......eqn (i)

MB=6x-2

or, B=6x-2-M......eqn (ii)

Now,

from eqn (i) and (ii)

x+8-M=6x-2-M

or, 8+2=6x-x-M+M

or, 10=5x

or, 10÷5=x

therefore, x=2

Again,

MB=6x-2

=6×2-2

=12-2

=10

is it correct

You can text 44 words in 1 minute. Write a proportion to help you find

Natalka [10]

Answer:

176 words

Step-by-step explanation:

1) well we want to find the amount of words we'd be able to type in 4 minutes. so, what i did was:

44 words = x

1 minutes = 4 minutes

2) now look at how i set up the proportion, notice how i left a variable of x for the value i didn't know.

3) we also know that 1 times 4 is 4, so it'd also make sense to also multiply the numerator by 4 too!!

4) multiplying 44 by 4 would get us our answer which is 176

im not the best at math but i this explanation helped <33
