Finding area of triangle??? Solving for x

1 answer:

5 0

Arctangent (lower left angle) = 12 / 5
arctangent (lower left angle) = 2.4
lower left angle = 67.38 degrees

sine (67.38) = x / 5
x = 0.92254 * 5
x = 4.6127

area = .5 * height * base
area = .5 * 4.6127 * 13
area = 29.983

Maria has a business designing and making custom T-shirts. Her cost for materials, in thousands of dollars, is given by M(t)=−3

Lady_Fox [76]

Answer:

$P(t) = -t^2 + 12t$

Step-by-step explanation:

Given

$M(t) = -3t^2 + 36t$ -- Cost

$S(t) = -4t^2 + 48t$ --- Income

Required

Determine P(t)

P(t) is calculated as:

$P(t) = Income - Cost\\$

$P(t) = S(t) - M(t)$

$P(t) = -4t^2 + 48t -(-3t^2 + 36t)$

Open bracket

$P(t) = -4t^2 + 48t +3t^2 - 36t$

Collect Like Terms

$P(t) = 3t^2 -4t^2 + 48t- 36t$

$P(t) = -t^2 + 12t$

A triangle has vertices on a coordinate grid at P(-10,1)P(−10,1), Q(-10,-7)Q(−10,−7), and R(-5,-7).R(−5,−7). What is the length,

lys-0071 [83]

Answer:

Step-by-step explanation:

Given the following coordinates of a triangle

P(-10,1)

Q(-10,-7)

R(-5,-7)

Required

Length of PQ

PQ = √(y2-y1)²+(x2-x1)²

From the coordinate;

x1 = -10, y1 = 1, x2 = -10 y2 = -7

Substitute

PQ = √(-7-1)²+(-10-(-10))²

PQ = √(-8)²+0²

PQ = √64

PQ = 8units

Hence the length of PQ in units is 8units
