Answer:

Below

Step-by-step explanation:

Area if cuboid =2(l*b+b*h+h*l)

= 2(7.5*5+5*2.3+2.3*7.5)

=2(37.5+11.5+17.25)

=2(66.25)

=103.75cm^3

What is the area of a triangle whose vertices are X(1, 1), Y(3, -1), and Z(4,4)?
shepuryov [24]

Answer:

Step-by-step explanation:

Note that in this diagram, point A represents point X, point B represents point Y, and point C represents point Z.

From the diagram, it appears as if \overline{XZ} \perp \overline{XY}. To determine if this is the case, we can find the slopes of both segments.

m_{\overline{XZ}}=\frac{4-1}{4-1}=1\\m_{\overline{XY}}=\frac{-1-1}{3-1}=-1

Since these slopes are negative reciprocals, we know that they are perpendicular.

This means we can use the formula A=\frac{1}{2}bh, where b is the base (XY) and h is the height (XZ).

  • Note these are interchangeable.

Using the distance formula,

XY=\sqrt{(3-1)^{2}+(-1-1)^{2}}=2\sqrt{2}\\XZ=\sqrt{(4-1)^{2}+(4-1)^{2}}=3\sqrt{2}

This means the area is \frac{1}{2}(2\sqrt{2})(3\sqrt{2})=\boxed{6}

Find the present value that will grow $1000 if the annual interest rate is 7.5% compounded quarterly for 5 years
Reil [10]

Answer:

911.3010934

Step-by-step explanation:

Formula:

A = P(1 + r/4)^n

In this case:

A = 100

P = ?

R = .075 (7.5%)

N = 5

---

1000 = P(1+.075/4)^5

1000 = P(1.01875)^5

1000 = P(1.097332163)

1000/1.097332163 = P

P = 911.301
