a 9ft ladder is placed 4.5 feet from the base of a wall. How high up will the ladder reach? Round to the nearest hundredth.
Answer:
[tex]\huge\boxed{7.79 \ \text{feet}}[/tex]
Step-by-step explanation:
We know that we have a 9 foot long ladder resting upon a wall, with an unknown height, but the ladder is 4.5 feet away from the wall.
This can be represented as a triangle, where x is the unknown side.

We can use The Pythagorean Theorem to find the value of x. The theorem states that [tex]a^2+b^2=c^2[/tex], where a and b are the lengths of the legs and c is the length of the hypotenuse.
However, we already know the hypotenuse and one leg. Therefore we can substitute inside the equation to find the missing value.
[tex]a^2 + 4.5^2 = 9^2\\\\a^2 + 20.25 = 81\\\\a^2 = 60.75\\\\a \approx 7.79[/tex]

Find the remainder when f(x) is divided by (x - k).
f(x) = 4x3 - 6x2 + 3x + 1; k= -2
Answer:
The remainder is -61
Step-by-step explanation:
The polynomial remainder theorem states that the remainder of the division of a polynomial f(x) by (x-r) is equal to f(r).
The given polynomial is:
[tex]f(x) = 4x^3 - 6x^2 + 3x + 1[/tex]
We need to find the remainder when f(x) is divided by x+2. According to the above-mentioned theorem, we only need to find f(-2) as follows:
[tex]f(-2) = 4(-2)^3 - 6(-2)^2 + 3(-2) + 1[/tex]
[tex]f(-2) = 4(-8) - 6(4) - 6 + 1[/tex]
[tex]f(-2) = -32 - 24 - 6 + 1=-61[/tex]
The remainder is -61

Step-by-step explanation:
A ball is thrown vertically upward with an initial velocity of 64 feet per second. The distance s (in feet) of the ball from the ground after t seconds is s=64t-16t^2 (a) At what time t will the ball strike the ground? (b) For what time t is the ball more than 48 feet above the ground?
Given:
The distance s (in feet) of the ball from the ground after t seconds is
[tex]s=64t-16t^2[/tex]
To find:
(a) At what time t will the ball strike the ground?
(b) For what time t is the ball more than 48 feet above the ground?
Solution:
(a)
We have,
[tex]s=64t-16t^2[/tex]
Substitute s=0, to find the time t when the ball strike the ground.
[tex]0=64t-16t^2[/tex]
[tex]0=16t(4-t)[/tex]
Using zero product property, we get
[tex]16t=0\Rightarrow t=0[/tex]
[tex]4-t=0\Rightarrow t=4[/tex]
Therefore, the ball strike the ground in initial condition (t = 0) and after 4 seconds (t = 4).
(b)
Now, s > 48, to find the time t when the ball will be more than 48 feet above the ground.
[tex]64t-16t^2\geq 48[/tex]
[tex]0> 16t^2-64t+48[/tex]
Divide both sides by 16.
[tex]0> t^2-4t+3[/tex]
[tex]0> t^2-t-3t+3[/tex]
[tex]0> t(t-1)-3(t-1)[/tex]
[tex]0>(t-1)(t-3)[/tex]
Related equation is [tex](t-1)(t-3)=0[/tex]. Zeroes are t=1,3. These two number divide the number line is three parts. (-∞,1),(1,3),(3,∞)
[tex]0>(t-1)(t-3)[/tex] inequality is true for only (1,3).
It is only possible when t lies in the interval (1,3).
Therefore, the ball will be more than 48 feet above the ground between 1 and 3 seconds.

What is the solution to this equation? 4- 5k = -21
a.5
b.21
c.17 over 5
4 over 5
Answer:
k = 5
Step-by-step explanation:
4 - 5k = -21
Transpose and subtract 4 from both sides:
4 - 4 - 5k = -21 -4
-5k = -25
Divide both sides by -5
-5k/-5 = -25/-5
k = 5
