Answer:
14) 21.136505024965 m
15) 43.076759215619 km
Step-by-step explanation:
14)
let h be the height of the lighthouse:
tan(41.3) = 18.7/h
Then
h = 18.7÷tan(41.5)
= 21.136505024965 m
………………………………………
15)
90-71.4 =18.6
Let s be the distance that the plane flew
towards the south:
tan(90 - 71.4) = s/128
Then
tan(18.6) = s/128
Then
s = tan(18.6)×128
= 43.076759215619 km
Answer:
56.
Step-by-step explanation:
46+10=56
Answer:
5 in. by 4 in.
Step-by-step explanation:
The proportion of 1/4 is larger than 1/6 so the new scale drawing is larger. The new scale drawing is the drawn blank. The dimensions are 5 in. x 4 in. for the background. The H's dimensions are 1/2 in. width and also 1 in. The height is about 4 in. Length, width and height are all dimensions which is what I was trying to find. I'm sorry if this didn't help I didn't really know what it was asking.
Answer:
The answer is 165/6, or 27 and one half.
Step-by-step explanation:
t = 0
t = 5
Step-by-step explanation:
(-10t^2+50t)/(t^2+4t+3)
I'm making t into x so its not confusing with the plus sign
(-10x^2+50x)/(x^2+4x+3)
with (x^2+4x+3) :
what 2 numbers when multiplied make 3 and when added make 4 ?
they are 1 and 3
(x+1)(x+3)
(-10x^2+50x)/(x+1)(x+3)
(-10x(x-5))/(x+1)(x+3) =0
(-10t(t-5))/(t+1)(t+3)=0
t = 0
t = 5
