Answer:

The answer to your question is x = -0.171

Step-by-step explanation:

Equation

                         3.^{8x + 4} - 5 = 13

Process

1.- Pass -5 to the right side

                         3.^{8x + 4} = 13 + 5

2.- Simplify

                        3.^{8x + 4}  = 18          

3.- Get logarithm in both sides of the equation

                  (8x + 4)log 3 = log 18

4.- Pass log 3 to the right side

                  8x + 4 = log 18 / log 3

5.- Solve for x

                  8x = log 18/log 3 - 4

                    x = 1/8 [log 18 / log 3 - 4]

6.- Use the calculator to find x

                    x = 1/8 [ 1.255/0.477 - 4]

                    x = 1/8 [ 2.631 - 4]

                    x = 1/8 [ -1.369]

                   x = -0.171

In a basketball shooting competition, each competitor shoots ten balls which are numbered from 1 to 10. The number of points ear
sp2606 [1]

Answer:

score 35 is not possible

Step-by-step explanation:

Here, the competitor misses exactly two shots

what we have here is that, if we added from the numbers between 1-10 , excluding exactly two numbers, which of the numbers in the option cannot be obtained by this addition

a) 52

1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10

Total is 55

if we removed (2 and 1)

we get 52

This is a possible score

b) 44

Here, we just have to remove 11

if we take off 10 and 1, we can have 44

c) 41

if we removed 4 and 10 ; we get 41

d) 38

if we remove 17, we get 38

so let us remove 10 and 7

e) 35

here, we have to remove 20

Now, no two numbers added between 1 and 10 exactly will give 20

The highest sum to be deducted is 9 + 10 which is 19

So the lowest possible score is 55-19 = 36

This means that the term 35 is not possible

HELP
Yakvenalex [24]

Answer:

5. 50.3 m²

6. 113.1 cm²

7. 102.1 yards²

8.  50.3 yards²

9.  452.2 ft²

10.379.8 ft²

Step-by-step explanation:

Area of  a circle = nr²

The circumference of a circle = 2nr

n = pi = 22/7

r = radius

the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.

A radius is half of the diameter

radius = diameter / 2

5. (22/7) x 4² = 50.3 m²

6.  (22/7) x 6² =113.1 cm²

7. radius = 11.4/2 = 5.7 yards

(22/7) x 5.7² =102.1 yards²

8. radius = 8/2 = 4 yards

(22/7) x 4² = 50.3 yards²

9. 2nr = 75.4 yards

2 x (22/7) x r = 75.4

to find r, divide both sides of the equation by 2 and 7/22

r = 12 ft

Area =  (22/7) x 12² = 452.2 ft²

10. 2nr = 69.1 yards

2 x (22/7) x r = 69.1

to find r, divide both sides of the equation by 2 and 7/22

r = 10.99 ft²

Area = (22/7) x 10.99² = 379.8 ft²

the tenth is the first number after the decimal place. To convert to the nearest tenth, look at the number after the tenth (the hundredth). If the number is greater or equal to 5, add 1 to the tenth figure. If this is not the case, add zero
