Solve for f.<br> 5 = f + 1<br> f=

4vir4ik [10]

Answer:

f=4

Step-by-step explanation:

1) first we have to get the "f" by itself. to do this we subtract the 1 from the right side of the equation.

2) and what you do to one side you ALWAYS do to the other side!!! so subtract 1 from the 5 also

3) this leaves you with 4=f

hope this helps!

Vector u = <11, 12>, v = <-16, 6>, and w = <4, -5>. Match each vector operation with its resultant vector expr

MAVERICK [17]

3u - 2v + w gives the resultant vector as; <49, 19>

8u - 6v gives the resultant vector as; <184, 60>

7v - 4w gives the resultant vector as; <61, 104>

u - 5w gives the resultant vector as; <-9, 37>

<h3>How to find the resultant of vectors?</h3>

We are given the vectors;

u = 11i + 12j

v = -16i + 6j

w = 4i - 5j

1) 3u - 2v + w gives the resultant vector as;

3(11i + 12j) - 2(-16i + 6j) + 4i - 5j

⇒ 33i + 36j + 32i - 12j + 4i - 5j

⇒ 49i + 19j

⇒ <49, 19>

2) 8u - 6v gives the resultant vector as;

8(11i + 12j) - 6(-16i + 6j)

⇒ 88i + 96j + 96i - 36j

⇒ 184i + 60j

3) 7v - 4w gives the resultant vector as;

7(11i + 12j) - 4(4i - 5j)

⇒ 77i + 84j - 16i + 20j

⇒ 61i + 104j

4) u - 5w gives the resultant vector as;

11i + 12j - 5(4i - 5j)

11i + 12j - 20i + 25j

-9i + 37j

R is the interior of angle TUV. The measure of RUV=30degrees, the measure of TUV=3x+16, and the measure of TUR=x+10. Find x and

choli [55]

Given

R is the interior of ∠ TUV.

m∠ RUV=30degrees, m∠ TUV=3x+16, and m∠ TUR=x+10.

Find the value of x and the m ∠TUV.

To proof

As given in the question

m ∠TUV=3x+16, and m ∠TUR=x+10

thus

m∠ RUV = m∠ TUV - m∠ TUR

= 3x + 16 - x -10

= 2x + 6

As given

m ∠RUV=30°

compare both the values

we get

30 = 2x + 6

24 = 2x

12 = x

put this value in the m ∠TUV= 3x+16

m ∠TUV= 12× 3 +16

= 52°

Hence proved

What is 1/6 plus 3/8 all together

zloy xaker [14]

$\frac{1}{6} + \frac{3}{8} = \frac{1\times 4}{6\times 4} + \frac{3\times 3}{8\times 3} = \frac{4}{24} + \frac{9}{24} = \frac{9+4}{24} = \boxed{\frac{13}{24}}}$
