Remember the order of operations: Parentheses, Exponents, Multiplication/Division, Addition/Subtraction

Solve the expressions in parentheses first.

There is an expression within parentheses that is also in an expression within brackets. Solve that expression first:

6 - 10 = -4

The expression in brackets will now read:

[4 - 3(-4)]

Multiply 3(-4):

3 \cdot -4 = -12

[4 - (-12)]

Solve the expression:

4 - (-12) = 4 + 12 = 16

The problem should now look like this:

(8-2)^2 + \frac{1}{4}(16)

Solve the expression in parentheses that has an exponent:

8 - 2 = 6

(6)^2 = 6 \cdot 6 = 36

Solve the term with 1/4 as a coefficient:

\frac{1}{4}(16) = 4

The expression should now look like this:

36 + 4 =  \boxed{40}

The answer is 40.

(8 - 2)² + 1/4[4 - 3(6 - 10)]

Solve this expression using PEMDAS. (M/D and A/S are not in order, they are solved from left to right)

  1. Parentheses
  2. Exponents
  3. Multiplication
  4. Division
  5. Addition
  6. Subtraction

According to PEMDAS, we are going to solve inside the parentheses (brackets) first.

Solve (6 - 10) inside the brackets first.

  • (8 - 2)² + 1/4[4 - 3(-4)]

Solve the multiplication inside the brackets (-3 * -4).

  • (8 - 2)² + 1/4[4 + 12]

Add 4 + 12 inside the brackets.

  • (8 - 2)² + 1/4[16]

Now solve (8 - 2) to complete the P step in PEMDAS.

  • (6)² + 1/4(16)

Next step in PEMDAS is E, exponents. Solve (6)².

  • 36 + 1/4(16)

Next step in PEMDAS is M, multiplication, so multiply 1/4(16).

  • 36 + 4

The last step is to add 36 and 4 together.

  • 36 + 4 = 40

Luiza is jumping on a trampoline. Ht models her distance above the ground (in m) t seconds after she starts
Damm [24]

Answer:

t=2.08 seconds.

Step-by-step explanation:

Well, in this example, H(t)=-0.6cos(2pi/2.5)t+1.5 should be equal to 1.2. If calculated, -0.6cos(0.8pi)t=1.2-1.5 which is equal to -0.6cos(0.8pi)t=-0.3, then cos(0.8pi)t=0.5. The value of cosine in terms of radians when it is equal to 0.5 is pi/3. So, cos(0.8pi)t=cos(pi/3). If simplified, (0.8pi)*t=5pi/3. pi's are cancelled out and t is calculated as 2.08333... If rounded to the nearest hundredth it is 2.08.

PLEASE HELP IMAGE ATTACHED!!! the area of this parallelogram is 120mm^2. Find the value of X
Marta_Voda [28]
The area of a parallelogram is the base times the height so:

A=bh, in this case:

A=hx

x=A/h, we are told that A=120mm^2 and h=10mm so

x=120mm^2/10mm

x=12mm
