Answer:
<h3>800 cm²</h3>
Step-by-step explanation:
Look at the picture.
We have three rectangles. The formula of an area of a rectangle:
l - length
w - width
Rectangle I:
Rectangle II:
Rectangle III:
The area of number 4:
Substitute:
<span>Based on hint and given formula, we can complete the problem. The question asks for square feet of grass so we know that we are solving for the area, A. It also tells us the height (looking downward) of the field is 75 ft,h, while the two bases are 125 ft and 81 ft (b1 and b2). So we can solve the equation.
A = 75((125+81)/2)
A = 75(206/2)
A = 75(103)
A = 7725
The area of the field is 7725 square feet.</span>
Answer:
aₙ = -2aₙ₊₁
Step-by-step explanation:
According to the sequence given 16, -8, 4, ...
a1 = 16
a2 = -8
a3 = 4
From the values, we can conclude thst;
a1 = -2(-8)
Since a2 = -8, then;
a1 = -2(a2)
Similarly
a2 = -2(4)
a2 = -2a3
The subsequent sequence are;
a3 = -2a4
The nth term will ne;
aₙ = -2aₙ₊₁
Hence the required recursive function is aₙ = -2aₙ₊₁
Answer:
ind f(x) and g(x) so that the function can be described as y = f(g(x)). (1 point) y = Four divided by x squared. + 9
=
12.5mg left at 6pm
Step-by-step explanation:
500mg x 15% = 75mg/hr
Taken at 8am and by 2pm that's 6/hrs 7 x 75mg/hr = 450mg
By 2pm only 50mg are left
Taken at 8am, by 6pm that's 10/hrs
With 50mg left and 4hrs to go
50mg ÷ 4 = 12.5mg
