Answer: 1/10 or 0.1
Step-by-step explanation:
-(-7 - 4x) = -2(3x - 4)
7 + 4x = -6x + 8
* subtract 7 from both sides
4x = -6x + 1
* Add 6x to both sides
10 x = 1
* Divide both sides by 10
x = 1/10 or 0.10

Watching a Helicopter Take Off At a distance of 58 ft from the pad, a man observes a helicopter taking off from a heliport. If the helicopter lifts off vertically and is rising at a speed of 55 ft/sec when it is at an altitude of 113 ft, how fast is the distance between the helicopter and the man changing at that instant? (Round your answer to one decimal place.)
The Pythagora´s Theorem, tell us that in a right triangle, the square of the hypothenuse (L²) is equal to :
L² = x² + y²
x and y are the legs.
The solution is
dy/dt = 48.9 ft/s
We know that in a right triangle:
L² = x² + y² (1)
If the helicopter lifts off vertically, that means x ( the horizontal distance between the observing man and the helicopter, maintains constant).
According to that, if we get derivatives with respect to time on both sides of equation (1) we get:
2×L× dL/dt = 0 + 2×y×dy/dt (2)
And
L = √ ( 58)² + ( 113)² = √12769 + 3364 = 127.02 ft
L = 127.02 ft when y = 113 ft
Now in equation (2) we know:
y = 113 ft dy/dt = 55 ft/s L = 127.02 we look for dL/dt
Then by substitution
2×127.02 × dL/dt = 2×113×55
254.04× dL/dt = 12430
dL/dt = 48.92
dL/dt = 48.9 ft/s

what is 0.95 as a simplified fraction?
Answer:
19/20
Step-by-step explanation:
A "simplified fraction" in this case is the ratio of two integers.
0.95 = 95/100 (the ratio of two integers), which in turn can be simplified:
95/100 = 19/20

Two positive numbers have a difference of 8. The larger number is two more than twice the smaller. Find the two numbers
Let the bigger number be 'p' and the smaller number 'p'.
Since the numbers have a difference of 8, then p - q = 8
& since the larger number is two more than twice the smaller, then
p = 2q + 2
⇒ (2q + 2) - q = 8 [by substituting for equation for p]
q = 6
Since q = 6,
⇒ p - 6 = 8
p = 14
∴ the smaller number is 6 and the bigger 14

PROBLEM SOLVING A water sample must be taken from water at least 20 feet deep. Find the depth of the water 50 feet
from shore.
50 ft
5 ft
21.5t
d
Not drawn to scale
The depth is
feet.
Is this an appropriate location for a water sample?
Using the principle of similar triangles, the appropriate depth to take the water sample should be 15 feets
Setting up the equation thus :
1.5 / d = 5 / 50
Cross multiply
1.5 × 50 = d × 5
75 = 5d
Divide both sides by 5
5d / 5 = 75/5
d = 15
Therefore, the appropriate depth to take the water sample is 15 feets.

point Find the length of segment CD with C(2,3) and D (-3, 15
Step-by-step explanation:
so, if the text is correct, the 2 points are
(2, 3) and (-3, 15).
the length of the line segment is the distance between both points.
did this we use Pythagoras for right-angled triangles.
c² = a² + b²
c is the Hypotenuse and the distance between both points. a and b are the legs (enclosing the 90 degree angle), which are simply the differences of the x and the y coordinates.
so,
distance² = (2 - -3)² + (3 - 15)² = 5² + (-12)² = 25 + 144 = 169
distance = sqrt(169) = 13 = length of line segment
