Answer:
y = -1/2 x - 13/2
Step-by-step explanation:
what is an equation of the line that is perpendicular to y-4=2(x-6) and passes through (-3,-5)
First, we need the slope of the given line.
y - 4 = 2(x - 6)
y - 4 = 2x - 12
y = 2x - 8
The slope of the given line is 2.
The slopes of perpendicular lines are negative reciprocals, so the slope of the perpendicular is -1/2.
y = -1/2 x + b
We use the given point as x and y and solve for b.
-5 = -1/2(-3) + b
-10 = 3 + 2b
2b = -13
b = -13/2
The equation of the perpendicular line is:
y = -1/2 x - 13/2
Answer:
45.54m
Step-by-step explanation:
Refer the attached figure
Scarlett's height = AB = 1.65 meters
She stands 90 meters away from the dam i.e. BE = AC = 90 m
She records the angle of elevation to the top of the dam to be 26º i.e. ∠DBE = 26°
Height of the Dam = DC = EC+DE
AB = EC = 1.65
In ΔBDE
Height of the Dam = DC =1.65+43.89=45.54 m
Hence the height of the dam is 45.54 m.
Yes this is correct you go u have the right answer as far as i know and i see
Using pemdas you can solve it. Pemdas stands for parentheses, exponents, multiply, divide, add, and subtract. So you look at the problem and you look if there’s any parentheses which is not so then you move onto exponents which there is. Two to the third power is equal to 8. The problem then becomes 28+87/3•8
Then you look for multiplication. 3•8=24
It’s now 28+87/24
Next is division so you do 87/24 = 3.6
Now it is 28+3.6=31.6
The answer is 31.6
Answer:
eli= £180, freda = £260, geoff = £360
Step-by-step explanation:
eli : freda : geoff
9 : 13 : 18
9 + 13 + 18 = 40 parts
800 / 40 = 20
therefore 1 part = £20
20 x 9 = £180
20 x 13 = £260
20 x 18 = £360
