Answer:

120 - x - 9 past 10am

Step-by-step explanation:

Call “x” the number of minutes it is before 12 noon. Measure time in minutes from 10am, so that 12 noon is 2*60 = 120 minutes after 10 am. The current time is 120 - x after 10 am. Nine minutes ago it was 120 - x - 9 past 10am.

How are the graphs of the functions f(x) = √16^x and g(x) =3√64^x related?

liberstina [14]

Answer:- The functions f(x) and g(x) are equivalent.

Explanation:-

Given functions:- $f(x)=\sqrt{16^x}$ and $g(x)=\sqrt[3]{64^x }$

Simplify the functions by using law of exponents

$(a^n)^m=a^{nm}$

Thus $f(x)=\sqrt{16^x}=\sqrt{(4^2)^x}=\sqrt{4^{2x}} =\sqrt{(4^x)^2}=4^x$

and $g(x)=\sqrt[3]{64^x}=\sqrt[3]{(4^3)^x}= \sqrt[3]{4^{3x}}= \sqrt[3]{(4^x)^3}=4^x$

⇒f(x)=g(x)

Therefore ,the functions f(x) and g(x) are equivalent.

One number is 6 less than 5 times the other number. Their sum is 60. Find the numbers.

OLEGan [10]

Answer:

The numbers are 11 and 49.

Step-by-step explanation:

x = 5y - 6 This is just the first sentence written as an equation.

x + y = 60 This is just the second sentence written as an equation.

5y - 6 + y = 60 Substitute x for what you know it is equal to

6y - 6 = 60 Collect like terms

6y = 66 Add 6 to each side

y = 11 Divide each side by 6

x = 5 × 11 - 6 Substitute y for what you know it is

x = 55 - 6 Simplify by working out 5 × 11 = 55

x = 49 Subtract 6 from 55 to get 49

Please assist me with this problem

Nimfa-mama [501]

Answer:

d. about 50 times larger

Step-by-step explanation:

The given expressions for magnitude (M) can be solved for the intensity (I). Then the ratio of intensities is ...

$\dfrac{I_2}{I_1}=\dfrac{I_0\cdot 10^{M_2}}{I_0\cdot 10^{M_1}}=10^{M_2-M_1}=10^{4.2-2.5}\\\\=10^{1.7}\approx 50$

The larger earthquake had about 50 times the intensity of the smaller one.
