Answer:

The second graph from the top left side.

Step-by-step explanation:

When the data 8, 9, 10, 11, 11, 14, 18, 28, 28, 29, 40, 41, 41, 44, 45, 47, 55 is drawn in histogram.

Then in first interval 0 - 9 there are two numbers ( 8, 9 ) so, this is shown by point 2 on y-axis

In second interval 10 - 19 there are five numbers ( 10, 11,11, 14, 18 )so, this is shown by point 5 on y-axis.

In third interval 20 - 29 there are three numbers ( 28,28, 29 )so, this is shown by point 3 on y-axis.

In fourth interval 30 - 39 there is no data to plot so, this interval will be blank.

In fifth interval 40 - 49 there are six numbers ( 40,41, 41,44,45,47 )so, this is shown by point 6 on y-axis.

In sixth interval 50 - 59 there is one number ( 55 )so, this is shown by point 1 on y-axis.

All these interpretation matches the <u>second graph from the top left side.</u>

9x^2 -c =d

add c to each side

9x^2 = c+d

divide by 9

x^2=(c+d)/9

take the square root on each side

x = +- sqrt ((c+d)/9)

simplify

x = +- 1/3 sqrt (c+d)

Answer: 1/3 sqrt (c+d), - 1/3 sqrt (c+d)

_30. Solve the following logarithmic equation: log8(x + 9) + 3 = 3
Bezzdna [24]

Answer:

A

Step-by-step explanation:

using the rule of logarithms

log_{b} x = n ⇒ x = b^{n}

log_{8} (x + 9) + 3 = 3 ( subtract 3 from both sides )

log_{8} (x + 9) = 0 , then

x + 9 = 8^{0} = 1 ( subtract 9 from both sides )

x = - 8

A right △ABC is inscribed in circle k(O, r). Find the radius of this circle if:
natta225 [31]

We have been given that a right △ABC is inscribed in circle k(O, r).

m∠C = 90°, AC = 18 cm, m∠B = 30°. We are asked to find the radius of the circle.

First of all, we will draw a diagram that represent the given scenario.

We can see from the attached file that AB is diameter of circle O and it a hypotenuse of triangle ABC.

We will use sine to find side AB.

\text{sin}=\frac{\text{Opposite}}{\text{Hypotenuse}}

\text{sin}(30^{\circ})=\frac{AC}{AB}

\text{sin}(30^{\circ})=\frac{18}{AB}

AB=\frac{18}{\text{sin}(30^{\circ})}

AB=\frac{18}{0.5}

AB=36

Wee know that radius is half the diameter, so radius of given circle would be half of the 36 that is \frac{36}{2}=18.

Therefore, the radius of given circle would be 18 cm.
