PLEASE HELP ! What is the value of the function at x = 3? Enter your answer in the box.

(8) = ཏ - (x + 3) what is the value of 8

lilavasa [31]

Answer:

$x = - 6$

Step-by-step explanation:

$(8) = ཏ - (x + 3) \\ 8 = ཏ - x - 3 \\ 2 - x = 8 \\ x - 2 = - 8 \\ x = 2 - 8 \\ x = - 6$

A ball is thrown vertically upwards from the ground. It rises to a height of 10m and then falls and bounces. After each bounce,

Citrus2011 [14]

${\huge{\fcolorbox{yellow}{red}{\orange{\boxed{\boxed{\boxed{\boxed{\underbrace{\overbrace{\mathfrak{\pink{\fcolorbox{green}{blue}{Answer}}}}}}}}}}}}}$

(i)

$\sf{a_n = 20 \times {( \frac{2}{3} )}^{n - 1} }$

(ii)

$\sf S_n = 60 \{1 - { \frac{2}{3}}^{n} \}$

Step-by-step explanation:

$\underline\red{\textsf{Given :-}}$

height of ball (a) = 10m

fraction of height decreases by each bounce (r) = 2/3

$\underline\pink{\textsf{Solution :-}}$

(i) We will use here geometric progression formula to find height an times

${\blue{\sf{a_n = a {r}^{n - 1} }}} \\ \sf{a_n = 20 \times { \frac{2}{3} }^{n - 1} }$

(ii) here we will use the sum formula of geometric progression for finding the total nth impact

$\orange {\sf{S_n = a \times \frac{(1 - {r}^{n} )}{1 - r} }} \\ \sf S_n = 20 \times \frac{1 - ( { \frac{2}{3} })^{n} }{1 - \frac{2}{3} } \\ \sf S_n = 20 \times \frac{1 - {( \frac{2}{3}) }^{n} }{ \frac{1}{3} } \\ \sf S_n = 3 \times 20 \times \{1 - ( { \frac{2}{3}) }^{n} \} \\ \purple{\sf S_n = 60 \{1 - { \frac{2}{3} }^{n} \}}$

In an honors math class of 25 students, 15 are boys and 10 are girls. On the final exam, 6 boys and 3 girls received a grade of

postnew [5]

Answer:

Step-by-step explanation:

b=boy

a= a on the exam

b=15

b∩a=6

b'∩a=3

b'∪a'=?

b'∪a'= b'+a'-b'∩a'

a= b∩a+b'∩a (law of total probability) = 9

a'= 25-9 = 16

b'= 25-15= 10

16+10-7=19

19/25= .76

Sue's Fruit Stand sells 20 different types of fruits. The table below shows the numbers of fruits that have certain percentages

Ksenya-84 [330]

Answer:

The first histogram is the answer.

Step-by-step explanation:

Like any other questions, you can use the process of elimination to answer this question.

There are only one fruit that has a water content of 60 - 64 %

Right away you can eliminate the second answer choice.

There are two fruits that has a water content of 65 - 69 %

All the other three has the same thing

There are only two fruits that has a water content of 70 to 74 %

Right away answer choice three can be eliminated

There are 4 fruits that are 75 - 79 % full with water

Both has same thing

There are 9 friuts that are 80 - 84 % full with water

THERE ARE 2 FRUITS THAT CONTAIN 85 - 89 % water

THE ANSWER IS THE FIRST HISTOGRAM.
