What single decimal multiplier would you use to increase by 9% followed by 3% decrease

Answer:

= 94

Step-by-step explanation:

To work out the multiplier, first add or subtract the percentage from 100, then convert to a decimal. Example: we want to add 20% to £110. To work out the multiplier, add 20 to 100, to get 120, and then change it to a decimal (divide by 100) to get 1.2. The answer is £110 x 1.2 = £132.

so to workout an increase of 9% followed by 3% we would do:

9% - 3% = 6%. convert = 0.06 = 100-6 = 94 converted into 0.94 x 100 = 94

F(x) = 3 sin x + 3 cos x

Darina [25.2K]

F ( x ) = 3 sim x + 3 cos x
f ` ( x ) = 3 cos x - 3 sin x
f `` ( x ) = - 3 sin x - 3 cos x = - 3 ( sin x + cos x )
The inflection points:
- 3 ( sin x + cos x ) = 0
sin x + cos x = 0
sin x = - cos x / : cos x
tan x = - 1
x 1 = 3π / 4
x 2 = 7π / 4
The function is concave up when f``(x) > 0
- 3( sin x+ cos x ) > 0
sin x + cos x < 0
tan x < - 1
f is concave up for:
x ∈ ( π/2, 3π/4 ) ∪ ( 3π/2, 7π/4)
f is concave down for:
x ∈ ( 0, π/2 ) ∪ ( 3π / 4, 3π/2 ) ∪ ( 7π / 4, 2 π ).

Please help ill give brainiest answer!

eduard

1. First of all, this is a isosceles triangle, meaning measurement I=58°, which makes it way easier to find T.

$58 + 58 + x = 180$

$116 + x = 180$

$x = 64$

1. m{t}°=64 m{I}°=58

2. This one is easy because algebra is the key.

$100 - x + 30 + 4x + 7x = 180$

Add like-terms.

$130 +10x = 180$

$10x = 50$

$\frac{50}{10} = x = 5$

x=5

The only thing that confuses me is the y. Is it 7xy, y as a side, or what? Feel free to reply

Answer:

The volume is 2140.98 inches³

Step-by-step explanation

The basketballs are spherical, and it is known that the volume of a sphere is

$V = \frac{4}{3}\pi r^{3}$

Where V is the volume of the ball and r is its radius

They tell us that the ball measures 8.8 inches wide. This means that its diameter is 8.8 inches.

It is known that the radius of a sphere is equal to half its diameter.

Therefore, the radius r of the ball is:

$r = \frac{8.8}{2}$

r = 4.4 inches.

Then, they tell us to consider that the walls of the ball are infinitely thin, which means that we should not take into account their thickness in the calculation of the volume.

We already have all the data we need, now we proceed to calculate the volume.

$V = \frac{4}{3}\pi(4.4)^{3}\\V = 356.83 inches^{3}$

Where V is the volume of only one of the balls

The volume of the six balls is V = 6 * 356.83 = 2140.98 inches³

Finally the volume is 2140.98 inches³
