Answer:

Complete the SquareSolve for x over the real numbers:(x - 8)^2 - 100 = 0

Add 100 to both sides:(x - 8)^2 = 100

Take the square root of both sides:x - 8 = 10 or x - 8 = -10

Add 8 to both sides:x = 18 or x - 8 = -10

Add 8 to both sides:Answer: x = 18 or x = -2

Step-by-step explanation: DONT TRUST THIS THOUGH

Angle QPS is an inscribed angle. Arc QS is the intercepted arc of that angle. The rule is that the intercepted arc is twice its angle measure. P measures 20 degrees, so arc QS measures 40 degrees. It just so happens that angle QTS is ALSO an inscribed angle intercepting arc QS. So angle QTS measures the same as angle P, 20 degrees. That's a. For b., we already stated the rule and figured out that minor arc QS is 40 degrees. For c., major arc QTS is 360 (the measure around the outside of a circle...EVERY circle in the world) minus the minor arc of 40. So major arc QTS measures 360 - 40 which is 320 degrees. There you go!

The value of a new car decreases by about 15% in the first year. How much will a car be worth after one year if its initial valu

Masja [62]

Answer:

(a)

$850.

(b)

$4250.

(c)

$4267.

Step-by-step explanation:

It is given that the value of a new car decreases by about 15% in the first year.

(a)

Now we are asked to find the cost of a car after one year; if we are given the initial value of car=$1000.

As the rate decreases by 15%.

that means we have to pay (100-15)% of the initial amount.

i.e. we have to pay 85% of the initial amount.

Hence the amount one has to pay= 85% of 1000.

which is equal to =85%×1000

⇒ = $\dfrac{85}{100}\times 1000\\\\=85\times 10\\\\=850$

Hence, the amount of car after one year when initaial amount is $1000 is:

$850.

(b)

if initial amount=$ 5000

then amount one has to pay after one year:

$85\%\times 5000\\ \\=\dfrac{85}{100}\times 5000\\\\=4250$

Hence, the amount of car after one year when initaial amount is $5000 is:

$4250.

(c)

if initial amount=$ 5020

then amount one has to pay after one year:

$85\%\times 5020\\ \\=\dfrac{85}{100}\times 5020\\\\=4267$

Hence, the amount of car after one year when initaial amount is $5020 is:

$4267.

Here we go ~

take value of pi = 3

r = radius = 5 cm

h = height = 9 cm

Let's calculate volume of Cylinder ~

$\qquad \sf \dashrightarrow \:v = \pi {r}^{2} h$

$\qquad \sf \dashrightarrow \:v = 3 \times {5}^{2} \times 9$

$\qquad \sf \dashrightarrow \:v = 3\times25 \times 9$

$\qquad \sf \dashrightarrow \:v = 75 \times 9$

$\qquad \sf \dashrightarrow \:v =67 5 \: \: cm {}^{3}$

That's all, ask me if you have any queries ~
