Simplify the expression. 5(x - z) + 4(y

While placing a compact disc into a CD player, you notice a small chip on it\'s edge. But you attempt to play the CD anyway by p

Vera_Pavlovna [14]

Answer:

(x, y) ≈ (-5.89, 1.16)

Step-by-step explanation:

We assume the CD is still accelerating at the same rate at the end of the given time period. The angular position will be found from ...

θ(t) = θ₀ + (1/2)a·t²

Filling in the numbers given, we get

θ(3.51) = (10π/180) + (1/2)(2.49)(3.51²) = 15.51306 . . . radians

The x-y coordinates will be found from ...

(x, y) = radius·(cos(θ), sin(θ)) ≈ 6·(-0.981066, 0.193674)

(x, y) ≈ (-5.89, 1.16)

_____

For the trig functions, the calculator must be in radians mode, unless you have converted the angles to degrees.

70% of 90 please give right answerrr

Natali5045456 [20]

Answer: 63

Step-by-step explanation: To find 70% of 90, first write 70% as a decimal by moving the decimal point two places to the right to get .70.

Next, the word "of" means multiply, so we have (.70)(90) which is 63.

So 70% of 90 is 63.

A. Which number is greater? 1/4 or 5/4 -3/4 or 5/8

Lilit [14]

Answer:

a. Which number is greater? 1/4 or 5/4 -3/4 or 5/8:

answer: 5/4

b. Which number is farther from 0? 1/4 or 5/4 -3/4 or 5/8:

answer: 5/4

c. Is the number that is farther from 0 always the greater number?:

answer: nah really.

A number can be further from zero but when it's a negative or positive. But negative value is less than zero.

${}^{ - } \infin \leqslant 0 \leqslant {}^{ + } \infin$

What is the value of the expression? Show all work. -9 - 6 + 8 ÷ -4 * -2?

nadya68 [22]

Step-by-step explanation:

To do Order of Operations, we need to go with the order of the formula, PEMDAS.

P= Parenthesis

E= Exponents

M= Multiply (Whatever Comes First in Equation: M and D)

D= Divide

A= Addition (Whatever Comes First in Equation: A and S)

S= Subtraction

---------------------------------------------

So, we need to start with parenthesis, there aren't any, so we move on to Exponents.

There are no Exponents either, so we start with division, then multiplication.

(We always have to go left to right).

So,

-9 - 6 + 8 / -4 x -2

-9 - 6 + -2 x -2

-9 - 6 + 4

Our problem is:

-9 - 6 + 4

We do subtraction, then addition. (Left to Right)

-9 - 6 + 4

-15 + 4

-11.

Therefore, the answer is -11.
