8 0

m(x)=58

Multiply the bracket by m

(m)(x)=mx

mx=58

Divide both sides by m

mx/m=58/m

Cross out m and m, divide by m and then becomes 1*1*x=x

x=58/m

Answer: x=58/m

 - The </span><span>simple interest is calculated quarterly.
 
 2. Then, to solve this exercise and calculate the </span><span>periodic interest rate of Marta's Account, you only have to divide the annual interest rate (7.2%) by 1/4 year. So, you have:
</span> 
 =(7.2%)(1/4)
 =(7.2%)/4

What is the average rate of change of f(x), represented by the table of values, over the interval [-3, 4]? x f(x) -6 27 -3 6 -1
USPshnik [31]

Answer:

<em>The correct option will be:  C.  3</em>

Step-by-step explanation:

The given table is..........

x :      -6      -3      -1      0      1      4

f(x) :  27     6      2      3      6     27

<u>The formula for average rate of change</u> is:   \frac{f(b)-f(a)}{b-a} , where [a,b] is the given interval.

Here the interval is [-3, 4]. So,  a=-3 and b=4

Now, plugging the values of a and b into the above formula, we will get........

\frac{f(4)-f(-3)}{4-(-3)}

<u>From the given table,</u> we will get  f(4)=27 and f(-3)=6

So, the average rate of change will be:  \frac{27-6}{4-(-3)}= \frac{21}{7}=3

What is the area? Please explain steps so I can attempt to understand
yarga [219]

Answer:

12 \sqrt{2}

Step-by-step explanation:

you can use hypotenuse formula

45-45-90 isosceles right triangle

so, 45= x

x² + x² = 24²

2x² = 24²

x²= 24.12

x= \sqrt{288}  = 12 \sqrt{2}

or :

you can use this rule: if you see a 45 45 90 isosceles right triagngle (you can look picture) 45=a cm and 90 = a\sqrt{2}

cm

so ;

a \sqrt{2}  = 24

a= 12 \sqrt{2}

hope this helps ^-^
