Answer:

C. 7

Step-by-step explanation:

The graph that is drawn here shows the altitude as a function of time. When the plane takes off from Chicago, the graph will start from the horizontal axis.

Next, when the plane takes 3 intermediate stops, altitude will touch the horizontal axis 3 times.

Next, when the plane lands in New York the altitude will touch the horizontal axis.

Next, when plane takes off from New York and takes an intermediate stop, altitude will touch horizontal axis.

Lastly the altitude will touch the axis when plane lands back in Chicago.  

So, cumulatively the altitude will touch the horizontal axis seven times.

Solving Exponential Equations (lacking a common base)
devlian [24]

Step-by-step explanation:

5ˣ⁻² = 6

Take log of both sides.

log 5ˣ⁻² = log 6

Use log exponent property.

(x − 2) log 5 = log 6

Solve for x.

x − 2 = log 6 / log 5

x = 2 + (log 6 / log 5)

x = 3.1133

Multiply<br> (2x + 5z)(7x - 6z)<br> Simplify your answer.
Ugo [173]

Hello!

Explanation:

Distributive property: a(b+c)=ab+ac

Multiply by the numbers.

Product it's going to be multiply by the numbers, fractions, decimals, factors, and multiples.

First, apply used their FOIL.

Foil: (a+b)(c+d)=ac+ad+bc+bd

2x*7x+2x(-6z)+5z*7x+5z(-6z)

Then you can also apply by the minus/plus sign.

2*7xx-2*6xz+5*7xz-5*6zz

And finally simplify by equation.

2*7xx-2*6xz+5*7xz-5*6zz

<em><u>Answer: =14x²+23xz-30z²</u></em>

Hope this helps!

solniwko [45]

<em>b</em><em> </em>for <em>books</em><em> </em>read. b=1x + 1. the amount of months he's been in the club goes for x and +1 because he already read a book before he joined. if you do easy math, he's been there for 8 months because he read 9 books. i probably got the equation backwards but this works both ways imo.

Is 3z-1 in standard form?
babunello [35]

Answer:

Yes because

Step-by-step explanation:

Is 3z-1 in standard form?

Yes becausestandard form of a polynomial, the value in the power of the variable such as z in the equation reduces from left to right. Therefore, 3z - 1 is in standard form since the z term comes to the left of the constant term
