Answer:
D = 9(x, y, z) = (2, 3, -4)Step-by-step explanation:
A suitable calculator can compute the determinant for you. It is ...
D = 9
Then the values of x, y, z are ...
(x, y, z) = (Dx, Dy, Dz)/D = (18/8, 27/9, -36/9)
(x, y, z) = (2, 3, -4)
The perimeter of a rectangle is 85 ft. The length of the rectangle is two (x plus 16) and the width is 3x - 1. What is the length of the rectangle?
Answers
Answer:
The length of the rectangle is 27 ft.
Step-by-step explanation:
To determine the length of the rectangle, we will first determine the value of x.
From the question,
The length of the rectangle is 2x + 16
The width is 3x - 1
and the perimeter is 85 ft
From the formula for perimeter of a rectangle which is given by
P = 2(l+w)
Where P is the perimeter
l is the length
and w is the width
Then, we can then write that
85 = 2(2x+16 + 3x - 1)
85 = 2(5x + 15)
85 = 10x + 30
10x = 85 - 30
10x = 55
x = 55/10
x = 5.5 ft
Since the length of the rectangle is 2x+16, substitute the value of x
Therefore
l = 2x + 16
l = 2(5.5) + 16
l = 11 + 16
l = 27 ft
Hence, the length of the rectangle is 27 ft.

x = -3, -2, or 2
Step-by-step explanation:
In the graph, we can look along the line f(x)=6 and see where the function intersects, noting the x-coordinate of each value. We see that the coordinates with a y-value of 6 are (-3, 6), (-2, 6), and (2,6). This means that x can equal either -3, -2, or 2 when f(x)=6.

Answers
Answer:
480 square inches
Step-by-step explanation:

Fred started a new e-commerce business and borrowed 15000 for 12 years to get the business up and running. The interest is 18000. Find the rate
Answers
Answer:
The rate is 6.94 %
Step-by-step explanation:
Given;
Amount borrowed by Fred to start up the e-commerce, P = 15000
time of investment, t = 12 years
interest, I = 18000
The rate is given by the following equation;
P = IRt
R = P / It
where;
R is the rate
P is the principal
I is the interest
t is the time
R = (15000) / (18000 x 12)
R = 0.0694
R = 6.94 %
Therefore, the rate is 6.94 %

Water is being drained from a container which has the shape of an inverted right circular cone. The container has a radius of 5.00 inches at the top and a height of 6.00 inches. At the instant when the water in the container is 4.00 inches deep, the surface level is falling at a rate of 0.7 in./sec. Find the rate at which water is being drained from the container.
Answers
The rate at which water is being drained from the container is;
dV/dt = 24.4 in³/s
I've attached an image showing this inverted cone with the corresponding letters to represent the height and radius.
We are given;
Radius of Cone; R = 5 inches
Height of cone; H = 6 inches
h = 4 inches
Height rate of change; dh/dt = 0.7 in/s
Looking at the image attached, we can use similar triangle property to derive the relationship;
r/R = h/H
Where r is the radius at the instant where dh/dt = 0.7 in/s
Thus;
r/5 = 4/6
r = (5 × 4)/6
r = 3.33 inches
Now, from r/R = h/H
We can write with initial values of cone and differentiate;
r/5 = h/6
6r = 5h
6(dr/dt) = 5(dh/dt)
Since dh/dt = 0.7 in/s
Thus;
dr/dt = (5/6) × 0.7
dr/dt = 0.5833
Volume of cone is given by;
V = ⅓πr²h
We can find the rate at which the rate at which water is being drained from the container using partial differentiation on the volume equation.
Thus;
dV/dt = ⅓π((2rh × dr/dt) + (r² × dh/dt))
Plugging in the relevant values, we have;
dV/dt = ⅓π((2 × 3.33 × 4 × 0.5833) + (3.33² × 0.7))
dV/dt = 24.4 in³/s

find the measures of one interior angle and one exterior angle of a regular polygon with 8 sides
one interior angle__________ one exterior angle___________
Answers
Answer:
one interior angle 135
one exterior angle 45
Step-by-step explanation:
Total measure of all angles in a 8 sided regular polygon = (n - 2)* 180
= ( 8 - 2 ) * 180
= 6 * 180
= 1080
Measurement of one interior angle = 1080 / 8 = 135
Interior angle and exterior angle make linear pair.
Measurement of one exterior angle = 180 - 135 = 45

An object is launched at 20 m/s from a height of 65 m. The equation for the height (h) in terms of time (t) is given by h(t) = -4.912 + 20t + 65. What is the
object's maximum height?
Answers
Answer:
The maximum height is the y-value of the vertex.
h(t) = -4.9t² + 20t + 65
a=-4.9 b=20 c=65
h(2) = -4.9(2)² + 20(2) + 65
= -19.6 + 40 + 65
