5 0
12 marshmallows and 8 graham crackers = 4 s'mores
12/4 = 3
8/4 = 2
3 marshmallows and 2 graham crackers = 1 s'more
3  x 3 = 9
2 x 3 = 6
Renee needs 9 marshmallows and 6 graham crackers to make 3 s'mores.

What is the length of the hypotenuse?
gayaneshka [121]

Answer:

Hello! answer: 5

Step-by-step explanation:

What you do to find the answer for these is do a^2+b^2=c^2 Basically meaning 4 × 4 + 3 × 3 will equal a number that you then find the suare root of square root just meaning a number multiplied by itself to equals that number so...

4 × 4 = 16

3 × 3 = 9

16 + 9 = 25

√25 = 5

5 × 5 = 25 therefore c = 5 hope that helps!

Find the velocity and position vectors of a particle that has the given acceleration and the given initial velocity and position
stira [4]

Answer:

v(t) = (2t+1) \mathbb{i} +3t^2 \mathbb{j} +4t^3 \mathbb{k}

r(t) = (t^2+t) \mathbb{i} +(t^3+2) \mathbb{j} +(t^4 - 3) \mathbb{k}

Step-by-step explanation:

The velocity vector is the integral of the acceleration vector i.e.

v(t) = \int a(t) dt

v(t) = \int (2 \mathbb{i}+6t \mathbb{j} 12t^2 \mathbb{k}) dt

v(t) = 2t \mathbb{i}+3t^2 \mathbb{j} 4t^3 \mathbb{k} + C_1

When t=0, v(0) = \mathbb{i}. Inserting these values in v(t),

C_1= \mathbb{i}

v(t) = 2t \mathbb{i}+3t^2 \mathbb{j} 4t^3 \mathbb{k} + \mathbb{i}

v(t) = (2t+1) \mathbb{i}+3t^2 \mathbb{j} 4t^3 \mathbb{k}

The position vector is the integral of the velocity vector i.e.

r(t) = \int v(t) dt

r(t) = \int ((2t+1) \mathbb{i}+3t^2 \mathbb{j} 4t^3 \mathbb{k}) dt

r(t) = (t^2+t) \mathbb{i}+t^3 \mathbb{j} t^4 \mathbb{k} + C_2

When t=0, r(t) =2\mathbb{j}-3\mathbb{k}. Inserting these values in r(t),

C_2=2\mathbb{j}-3\mathbb{k}

r(t)= (t^2+t) \mathbb{i}+t^3 \mathbb{j}+ t^4 \mathbb{k} + 2\mathbb{j}-3\mathbb{k}

r(t) = (t^2+t) \mathbb{i}+(t^3+2) \mathbb{j}+ (t^4-3) \mathbb{k}
