Answer:
Step-by-step explanation:
66=2(w+5)+2w L=14+5
66=2w+10+2w L=19
66=4w+10
-10
56=4w/4
14=w
Answer:
a) The debris was 256 feet into the air after 2 seconds of the explosion.
b)
Step-by-step explanation:
We are given the following in the question:
Initial Velocity = 160 feet per second
The above function gives the height in feet and t is seconds after the explosion.
a) Height of the debris 2 second(s) after the explosion.
We put t = 2 in the above function
Thus, the debris was 256 feet into the air after 2 seconds of the explosion.
b) Factor the polynomial
The y intercept is (0,-4) and we know the slope is 3. So yes (2,3) is a point on the line y=3x-4
Another way of saying 30% is 30/100. Since 15 is 30/100 of another number, we can multiply 15 by the reciprocal of 30/100. This gives us:
15 * 100/30
Therefore, The original is 1500/30, or just 50
Answer: 50
Hope this helped!! :D

You can use the Pythagorean Theorem to find the length of the third side AB (Identified as "x" in the figure attached in the problem), which says that in a right angled triangle, the square of the hypotenuse is equal to the sum of the squares of the legs:
a² = b²+c²
As we can see the figure, the triangle does not have an angle of 90°, but it can be divided into two equal parts, leaving two triangles with a right angle. We already have the values of the hypotenuse and a leg in triangle "A" , so we can find the value of the other leg:
b = √(a²-c²) b = √(10²-4²)
b = 9.16
With these values, we can find the hypotenuse in the triangle "B":
x = √b²+c²
x = √(9.16)²+(4)²
x = 10
