Answer:

First notice that θ is in quadrant I, where the sine and tangent will also be positive.

Then draw the angle in quadrant I. Drop a perpendicular to the x axis.

Since cosθ= 7/25, label the horizontal leg 7, and the hypotenuse 25; the vertical leg will be 24 by Pythagorean theorem.

Then sinθ=vertical/hypotenuse=  24/25 and tanθ= vertical/horizontal=  24/7

Write a system of equations that could be used to solve the situation described below.
attashe74 [19]

If there are 12 coins under the couch and every coin is either a nickel or a penny and together they are forming 32 cents then the equations which represent the problem will be x+y=12, 0.01x+0.05y=0.32. The correct option is B which is x+y=12, 0.01x+0.05y=0.32.

Given There are 12 coins and total money is 32 cents.

Let the number of pennies be x and the number of  nickels be y.

According to question there are 12 coins so the first equation becomes:

x+y=12.

Then we have been told that together they amount to 32 cents.

We know that 1 penny is 1 cent coin and 1 nickel is 5 cent coin so the equation becomes :

1*x+5*x=32

x+5y=32

converting into dollar

0.01x+0.05y=0.32.

Hence the right equations showing the problem of nickel and pennies are x+y=12, 0.01x+0.05y=0.32.

Zeek then want to ride his bike to the old spaghetti factory. He wondering if he should bike 1 mile north, then 0.5 miles direct
frosja888 [35]

Answer:

He should travel directly

Step-by-step explanation:

Given

x = 0.5 --- East

y =1 --- North

If he goes through east north direction, the distance (d) traveled is:

d = x + y

d = 0.5 + 1

d = 1.5 mile

If he travels directly, the distance (d) is:

d = \sqrt{x^2 + y^2} ---- Pythagoras theorem

d = \sqrt{0.5^2 + 1^2}

d = \sqrt{0.25 + 1}

d = \sqrt{1.25}

d = 1.12mile

By comparison, he will travel the shortest distance if he travels directly because 1.12 < 1.5

<em>Hence, he should travel directly</em>
