Vector u has its initial point at (15, 22) and its terminal point at (5, -4). Vector v points in a direction opposite that of u,

and its magnitude is twice the magnitude of u. What is the component form of v?

Though the vectors are going in opposite directions, their terminal and starting points are the same, just switched, check the picture below.

recall the component for (a,b), (c,d) is just (c-a , d-b), 

the component form for "v" is then

(5, -4), (15, 22) => (15 - 5, 22-(-4)) => (15 - 5, 22+4) => (10 , 26).

and since "v" is twice as long as "u", then its form is 2v, or

2(10 , 26) => (20, 52)

What is the value of the expression
Arturiano [62]

Answer:

OA) 14

Step-by-step explanation:

2((7+1)-1)

2(8-1)

You could expand the brackets then simplify or just simplify now. It will be better to simplify now though but I will do both methods.

Simplifying first:

2(7) = 2 × 7 = 14

Our answer is 14 So answer is OA) 14

Expanding first then simplifying:

2(8-1) = 16-2 = 14

Our answer is 14 So answer is OA) 14

Answer:

64/3 tablespoons of sugar for 32 ounces of water

Step-by-step explanation:

In these kinds of questions it is nice to find how muc of 1 thing there is for every ONE of another.  so 8 tablespoons of sugar for 12 ouncesof water you can divide both sides by 8 or 12.

Dividing it by 8 gets 8/8 = 1 tablespoon of sugar for 12/8 = 1.5 ounces of water.

Dividing by 12 gets 8/12 = 2/3 tablespoon of sugar for 12/12 = 1 ounce of water.

Now you can take one or the other and multiply it to fit whichever you want to fit a ratio.

It asks what happens if you use 32 ounces of water, so lets use the ratio where we hae 1 ounce, then multiply everything by 32.

2/3 tablespoon of sugar for 1 ounce of water

Multiply by 32 and you get 32*(2/3) = 64/3 tablespoons of sugar for 32 ounces of water

Please help me with this please and thank you
Alina [70]

Step-by-step explanation:

y = ax^n + bx^(n-1) ... + z

(0, 1) tells us that the constant term z = 1.

because x = 0 eliminates all other terms. and as the sum is 1, that means z = 1.

for the other pairs I strongly suspect

(-1, 3) : 2×(-1)² + 1 = 2×1 + 1 = 3

(-2, 9) : 2×(-2)² + 1 = 2×4 + 1 = 9

so, the fitting equation is

y = 2x² + 1
