What is 1.8×10 + 8.4×10

2 answers:

8 0

$1.8*10+8.4*10$ is the equation

Basically, you are multiplying 1.8 and 8.4 by itself ten times but here is a tip:

When multiplying by ten, move the decimal once to the right

So $1.8*10=18.$ and $8.4*10=84.$

That leaves $18+84$ which is $102$

Answer: 102

In a survey of 100 students of Surkhet, 65 like to play football, 55 like

Katyanochek1 [597]

Answer:

15 students do not like either sport

Step-by-step explanation:

See the attached image.

Step 1: put 35 in the "like to play both" (intersection) area.

Step 2: subtract those 35 from the 65 football players. 65 - 35 = 30 players like football but not cricket. Put 35 in the football but not cricket area.

Step 3: subtract 35 from the 55 cricket players. 55 - 35 = 20 players like cricket but not football. Put 20 in the cricket but not football area.

Step 4: Add the 30 + 35 + 20 = 85 together. So 85 players are accounted for as players of one or more sports.

Step 5: 100 - 85 = 15 must be the number of students who did not like either sport. Put 15 in the area outside both circles.

Which ordered pairs lie on the graph of the exponential function f(x)=2^(x+4)−8?

natka813 [3]

Given the function

$f(x)=2^{(x+4)}-8$

Consider the point (2, 56) i.e. when x = 2

$f(x)=2^{2+4}-8 \\ \\ =2^6-8=64-8 \\ \\ =56$

Therefore, point (2, 56) lie on the graph of the given exponential function.

Consider the point (-2, -4) i.e. when x = -2

$f(x)=2^{-2+4}-8 \\ \\ =2^2-8=4-8 \\ \\ =-4$

Therefore, point (-2, -4) lie on the graph of the given exponential function.

Consider the point (8, 0) i.e. when x = 8

$f(x)=2^{8+4}-8 \\ \\ =2^{12}-8=4,096-8 \\ \\ =4,088$

Therefore, point (8, 0) does not lie on the graph of the given exponential function.

Consider the point (24, 1) i.e. when x = 24

$f(x)=2^{24+4}-8 \\ \\ =2^{28}-8=268,435,456-8 \\ \\ =-268,435,448$

Therefore, point (24, 1) does not lie on the graph of the given exponential function.
