An 8-foot ladder is leaning against a wall. The top of the ladder is 5.5 feet from the ground. What is the distance from the bottom of the ladder to the wall?
a
3.7
b
9.7
c
5.8
d
1.6
someone please answer i

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204

a. 32 degrees

step-by-step explanation:

here we have to use the rule.

m∠e = 1/2 (major arc - minor arc)

m∠e = 1/2 (212 - 148)

m∠e = 1/2 (64)

m∠e = 32 degrees

answer: a. 32 degrees

you

60 for the first and 130 for the second

step-by-step explanation:

time is equal to distance over rate so

t = d/r

need a little bit more information for the second question.
