In ∆ASR, W, E and N are midpoints. Determine the lengths of each segment using the number bank.
NikAS [45]

9514 1404 393

Answer:

  A)  AS = 60

  B)  WE = 20

  C)  EN = 25

  D)  AR+RS-AS = 30

Step-by-step explanation:

Each midsegment is half the length of the parallel side. Each side is twice the length of the parallel midsegment.

A) AS = 2(WN) = 2(30) = 60

B) WE = RS/2 = 40/2 = 20

C) EN = AR/2 = 50/2 = 25

D) AR +RS -AS = 50 +40 -60 = 30

What is -4(-4+3)+2 squared. use order of operations.
sineoko [7]
To solve this, first solve the part of the equation in parentheses: (-4+3) = -1. Then multiply using the exponent 2 squared is 2×2 which is 4. Now the equation is -4(-1)+4. Next you multiply, -4(-1)=4. You are then left with 4+4 which equals 8.

The table shows the volume of water in a tank after it has been filled to a certain height.
Lilit [14]

Functions and tables can be used to model real world situations.

The equation that represents volume is: \mathbf{V(h) = 1.05(h)^3}

From the table, we have:

\mathbf{h \to V}

\mathbf{0 \to 0}

\mathbf{1 \to 1.05}

\mathbf{2 \to 8.40}

\mathbf{3 \to 28.35}

The table can be rewritten as:

\mathbf{h \to V}

\mathbf{0 \to 1.05 \times 0^3}

\mathbf{1 \to 1.05 \times 1^3}

\mathbf{2 \to 1.05 \times 2^3}

\mathbf{3 \to 1.05 \times 3^3}

Replace 0, 1, 2 and 3 with h

\mathbf{h \to 1.05 \times h^3}

The above expression means that:

\mathbf{V(h) = 1.05 \times h^3}

Rewrite as:

\mathbf{V(h) = 1.05(h)^3}

Hence, the equation that represents volume is: \mathbf{V(h) = 1.05(h)^3}
