7 0

Answer:21v/22

Step-by-step explanation:

Circumference of a circle=2×π×radius

6v=2×22/7×r

7×6v=2×22×r

42v=44r

Radius=42v/44

Radius=21v/22

4, Write an inequality to compare the numbers 7 1/8 v50
Anarel [89]

Answer:

see the explanation

Step-by-step explanation:

we know that

using a calculator

7\frac{1}{8}=7+\frac{1}{8}= 7.125

\sqrt{50}= 7.071

Compare the numbers

Seven an eighth is greater than the square root of fifty.

7\frac{1}{8} > \sqrt{50}  

or

Square root of fifty is less than seven an eighth

\sqrt{50}

Solve log4 (y – 9) + log4 3 = log4 81.
avanturin [10]

\text{Domain}\\\\y-9 > 0\to y>9\\\\------------------------\\\\\log_4(y-9)+\log_43=\log_481\qquad\text{use}\ \log x+\log y=\log(xy)\\\\\log_4[3(y-9)]=\log_481\qquad\text{use distributive property}\\\\\log_4(3y-27)=\log_481\iff3y-27=81\qquad\text{add 27 to both sides}\\\\3y=108\qquad\text{divide both sides by 3}\\\\\boxed{y=36}\in D\\\\Answer:\ \boxed{y=36}

Solve 4 cos2x-3 = 0 for all real values of x.
vichka [17]

4 cos² x - 3 = 0

4 cos² x = 3

cos² x = 3/4

cos x = ±(√3)/2

Fixing the squared cosine doesn't discriminate among quadrants.  There's one in every quadrant

cos x = ± cos(π/6)

Let's do plus first.  In general, cos x = cos a has solutions x = ±a + 2πk integer k

cos x = cos(π/6)

x = ±π/6 + 2πk

Minus next.

cos x = -cos(π/6)

cos x = cos(π - π/6)

cos x = cos(5π/6)

x = ±5π/6 + 2πk

We'll write all our solutions as

x = { -5π/6, -π/6, π/6, 5π/6 } + 2πk integer k
