Answer:

Exponentials and logarithms are inverses of each other.

Step-by-step explanation:

Exponentials and logarithms are inverses of each other.

For logarithmic function:

Domain = \left ( 0,\infty  \right ), Range = \left ( -\infty ,\infty  \right )

Vertical asymptote is y - axis.

x - intercept is (1,0)

For exponential function:

Domain = \left ( -\infty ,\infty  \right ), Range = \left ( 0,\infty  \right )

Horizontal asymptote is x - axis.

y- intercept is (0,1)

Both exponential and logarithmic functions are increasing.

For example:

Solve: \log x=\frac{\log 5+\log 3}{\log 3^2}

\log x=\frac{\log 5+\log 3}{\log 3^2}\\\log x=\frac{\log (5\times 3)}{2\log 3}\,\,\left \{ \because \log (ab)=\log a+\log b\,,\,\log a^b=b\log a \right \}\\=\frac{\log 15}{2\log 3}

\Rightarrow \log x=\frac{\log 15}{2\log 3}\\\Rightarrow x=e^{\frac{\log 15}{2\log 3}}\,\,\left \{ \because \log x=y\Rightarrow x=e^y \right \}

Three friends each have some ribbon. Carol has 90 inches of ribbon, Tino has 7.5 feet of ribbon, and Baxter has 3.5 yards of rib
erastovalidia [21]

Answer: 306 inches or 25.5 feet or 8.5 yards.

Step-by-step explanation:

Given: Carol has 90 inches of ribbon, Tino has 7.5 feet of ribbon, and Baxter has 3.5 yards of ribbon.

1 feet = 12 inches

length of ribbon Tino has = 12 x 7.5 = 90 inches

1 yard = 36 inches

length of ribbon Baxter has = 3.5 x 36 = 126 inches

Total ribbon they have = (length of ribbon Carol has) + (length of ribbon Tino has) + (length of ribbon Baxter has)

= (90+90+126) inches

= 306 inches

In feet , Total ribbon = \dfrac{306}{12}\text{ feet}   [\text{ 1 inch}=\dfrac{1}{12}\text{ feet}]

=\text{25.5 feet}

In yards, Total ribbon =\dfrac{25.5}{3}\text{ yards}    [\text{1 feet}=\dfrac{1}{3}\text{ yard}]

=\text{ 8.5 yards}

Hence, the total length of ribbon the three friends have is 306 inches or 25.5 feet or 8.5 yards.

Can someone plz explain how to do this Algebra 1 A=1/2(a+b)h for h
Alex_Xolod [135]
<span>A=1/2(a+b)h for h.

First, you need to get rid of 1/2, so divide both sides by 1/2.
A/(1/2) = (a + b)h

You can simplify the </span>A/(1/2) by multiplying by the reciprocal of 1/2, so 2/1.

2A = (a + b)h

Now divide both sides by (a+b).

2A/(a+b) = h
