Hi! The temperature would be 18°.

There was a 4 hour period between 5 and 9 a.m.

So, I just took -10, and added 7 four times.

-10 + 7 + 7 + 7 + 7 = 18

Hope this helps you! Happy thanksgiving, here's a turkey!

Find the x-intercept and y-intercept of the liné.<br> - 6x + 5y = 21
Hunter-Best [27]

Answer:

x=-3.5 or -7/2 (same thing)

y=21/5

Step-by-step explanation:

x intercept is when y=0

y intercept is when x=0

so

x intercept is

-6x=21

x=21/-6

x=-3.5

y intercept is

5y=21

y=21/5

A special box designed to hold an antique artifact is shaped like a triangular prism. The surface area of the box is 421.2 squar
Oksanka [162]
The area of the base is:
 A = root ((s-a) * (s-b) * (s-c) * (s))
 Where,
 a, b, c: sides of the triangle
 s = (a + b + c) / 2
 We have then:
 s = (9 + 9 + 9) / 2
 s = 13.5
 A = root ((13.5-9) * (13.5-9) * (13.5-9) * (13.5))
 A = 35.07
 Then, the surface area of the prism is:
 S.A = 2 * A + 9h + 9h + 9h
 Where,
 h: height of the prism:
 Substituting values:
 421.2 = 2 * (35.07) + 9h + 9h + 9h
 Clearing h:
 27h = (421.2 - 2 * (35.07))
 h = (421.2 - 2 * (35.07)) / (27)
 h = 13
 Answer:
 
the height of the box is:
 
h = 13 inches

What is the equation of the asymptote for this function?
77julia77 [94]

The equation of the horizontal asymptote for this function f(x) = (1/2)^x + 3 is option D y = 3.

<h3>When do we get horizontal asymptote for a function?</h3>

The line y = a is horizontal asymptote if the function f(x) tends to 'a' from the upside of that line y = a, or from downside of that line.

The function is given as;

f(x) = (1/2)^x + 3

The function is Exponential functions.

Exponential functions have a horizontal asymptote.

The equation of the horizontal asymptote is option D y = 3.
