zubka84 [21]

Answer:

n-3

Step-by-step explanation:

for every input, the output is three less (4-3=1, 7-3=4, 8-3=5). That rule needs to stay consistent, so no matter what the input is (n), the output is always going to be three less than, making it y or output=n-3

Vector v has a direction of (5,3) find the direction angle for v to the nearest degree
Vesnalui [34]

Answer:

31^{\circ}

Step-by-step explanation:

We have been given that vector v has a direction of (5,3). We are asked to find direction angle for v to nearest degree.

We know that direction of vector with components (a,b) can be determined by \theta=\text{tan}^{-1}(\frac{b}{a}).

Upon substituting the components of given vector in above formula, we will get:

\theta=\text{tan}^{-1}(\frac{3}{5})

\theta=30.9637565^{\circ}

Upon rounding to nearest degree, we will get:

\theta\approx 31^{\circ}

Therefore, the direction angle for vector v is 31 degrees.

Gabby received change worth $2.10. She received 3 more dimes than nickels and 4 less quarters than nickels. How many of each kin
xz_007 [3.2K]

Answer:

Gabby received

7 nickels

10 dimes

3 quarters

Step-by-step explanation:

Let

x----> the number of dimes

y----> the number of nickels

z---> the number of quarters

Remember that

1 dime=$0.10

1 nickel=$0.05

1 quarter=$0.25

we know that

0.10x+0.05y+0.25z=2.10 ------> equation A

x=y+3-----> equation B

z=y-4 -----> equation C

substitute equation B and equation C in equation A and solve for y

0.10(y+3)+0.05y+0.25(y-4)=2.10

0.10y+0.30+0.05y+0.25y-1=2.10

0.40y=2.10-0.30+1

0.40y=2.80

y=7 nickels

<em>Find the value of x</em>

x=y+3 -----> x=7+3=10 dimes

<em>Find the value of z</em>

z=y-4 -----> z=7-4=3 quarters

therefore

Gabby received

7 nickels

10 dimes

3 quarters
