Answer:

about 76.2°

Step-by-step explanation:

The geometry can be modeled by a right triangle with the given dimensions being the side opposite the angle (height = 33,500 ft) and the side adjacent to the angle (8,200 ft). The fact that you know these two sides suggests the inverse of the tangent function may be useful.

Tan = Opposite/Adjacent

tan(angle) = (33,500/8,200)

angle = arctan (335/82) ≈ 76.246°

The angle of elevation is about 76.2°.

Please help what is the area and the perimeter of these two shapes????

34kurt

Answer:

Pink:

A. 87 m²

P. 50 m

Yellow:

A. 132 m²

P. 76 m

Step-by-step explanation:

You can cut the shapes up to find the area.

Pink Figure: (not cut up)

(13×7)-(4×1)=

91-4=

87 m²

(1+1+4+4)+(7+13+7+13)=

10+40=

50 m

Yellow Figure:

(14×4.5)+((14-9-3)×3)+((12-4.5-3)×14)=

(14×4.5)+(2×3)+(4.5×14)=

63+6+63=

132 m²

14+4.5+3+3+3+4.5+14+4.5+9+3+9+4.5=

76 m

Suppose f is an exponential function and:

Nastasia [14]

Answer: a) $b= p(1 + r)^1$ b) $c= p(1 + r)^n$ c) $d= p(1 + r)^m$ d) $b^n=c$

Step-by-step explanation:

Since f is an exponential function.

So, it is expressed as

$f = p(1 + r)^$

Here f is the present value

p is the initial value

r is the rate of growth per time period

t is the time period.

(a) b represents the 1-unit growth factor for f.

$b= p(1 + r)^1$

(b) c represents the n n-unit growth factor for f.

$c= p(1 + r)^n$

$d= p(1 + r)^m$

Write a formula that expresses c in terms of b.

Since

$b=p(1+r)^1\\\\So,\\\\b=p(1+r)^{n\times \frac{1}{n}}\\\\b=(p(1+r)^n)^{\frac{1}{n}}\\\\b=c^{\frac{1}{n}}\\\\b^n=c$

Hence, a) $b= p(1 + r)^1$ b) $c= p(1 + r)^n$ c) $d= p(1 + r)^m$ d) $b^n=c$
