Is there an x intercept in the equation 60*1.15^x
Natali [406]

Answer:

No

Step-by-step explanation:

The equation 60*1.15^x is an exponential function. Exponential functions do not cross the x-axis unless they have been shifted down through subtraction in the function. All exponential functions have asymptotes that the function approaches but never crosses or touches. This function has an asymptote at the x-axis.

A scale drawing has a scale of 1/4in:12ft. Find the length on the drawing for each actual length. 15 ft.
leonid [27]
So the ratio is at ¼ : 12, namely the drawing has ¼ inch to an actual 12 feet.

so, what would it be for an actual 15 feet on the drawing then?

\bf \begin{array}{ccll}
\stackrel{inches}{drawing}&\stackrel{feet}{actual}\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
\frac{1}{4}&12\\\\
d&15
\end{array}\implies \cfrac{\quad \frac{1}{4}\quad }{d}=\cfrac{12}{15}\implies \cfrac{\quad \frac{1}{4}\quad }{\frac{d}{1}}=\cfrac{12}{15}
\\\\\\
\cfrac{1}{4}\cdot \cfrac{1}{d}=\cfrac{12}{15}\implies \cfrac{1}{4d}=\cfrac{12}{15}\implies 15=48d\implies \cfrac{15}{48}=d\implies \cfrac{5}{16}=d

The length of a rectangular prism is three times as long as its width, and its height is two feet longer than its width. If the
aivan3 [116]
A rectangular prism is a polyhedron with six rectangular faces. To fully define a rectangular prism, one must know its length, width and height. The volume of a rectangular prism is expressed as the product of its dimensions - length, width and height. To calculate for its width, we use the volume formula.

V = l x w x h
From the given, we have:
l = 3w
h = 2 + w
V = 135 ft^3

Substituting the given expressions,
135 ft^3 = 3w (w) (2+w)
135 ft^3 = 6w^2 + 3w^3

Solving for w, we obtain the following values:
w1= 3
w2 = 2.5 + 2.96i
w3 = 2.5 - 22.96i

Since width should not have a negative value, the value of w should be 3 ft.
