Answer:

720

Step-by-step explanation:

Since we are choosing a subset of 3 people from a set of 10 people, and arranging the 3 people according to relative strength, the answer can be obtained by computing P(10,3).

 

 P(10,3)=10! / (10-3)!

= 10!/7!

Rewrite  10 !  as  

10 * 9  * 8  * 7 !  / 7!

Cancel the common factor of  7 !  and divide ( 10  * 9 * 8 ) by  1

10  * 9  * 8 = 720

21 and 22 are complementary angles. The measure of Z1 is 60°. The
Lemur [1.5K]

Answer:

The value of x is 7

Step-by-step explanation:

Complementary angles have a sum of 90°, therefore the equation to solve for x is:

∠1+∠2=90°

60°+5(x-1)°=90°

5(x-1)=30°

x-1=6

x=7

So the value of x is 7

Changing Bases to Evaluate Logarithms in Exercise, use the change-of-base formula and a calculator to evaluate the logarithm. Se
son4ous [18]

Answer:

The question is incomplete, the complete question is  "Changing Bases to Evaluate Logarithms in Exercise, use the change-of-base formula and a calculator to evaluate the logarithm. See Example 9.  log_{4}7.

log_{4}7=1.404\\

Step-by-step explanation:

From the general properties or laws of logarithm, we have the

log_{a}b=\frac{logb}{loga} \\

where both log are now express in the natural logarithm base.

i.e log_{a}b=\frac{lnb}{lna}\\

hence we can express our log_{4}7=\frac{ln7}{ln4} \\.

the value of ln7 is 1.9459 and ln4 is 1.3863

Hence  log_{4}7=\frac{ln7}{ln4}=\frac{1.9459}{1.3863}\\.

log_{4}7=1.404\\

How to Graph y=4/5x-7
densk [106]
You start at the y axis and go down 7 so the coordinate is (0, 7) then you move to the right five spaces from (0, 7) and go up 4 from the spot you moved right 7. This should have a positive slope
