Answer:

Part (A) → x = 5

Part (B) → m(arc RS) = 55°

Step-by-step explanation:

In the picture attached,

RU and SV are the diameters of the given circle.

Part (A),

Since RU is the diameter,

m(arc RVU) = 180°

m(arc RV) + m(arc VU) = 180°

(24x + 5) + (10x + 5) = 180

34x + 10 = 180

34x = 170

x = $\frac{170}{34}$

x = 5

Part (B),

Since m(arc RS) = m(arc VU) [Angles intercepted by these arcs at the center are equal because they are the vertical angles]

m(arc RS) = (10x + 5)

= (10×5 + 5)

= 55°

What are the values of x in the equation x2 – 6x + 9 = 25? x = –2 or x = 8 x = –1 or x = –11 x = 1 or x = 11 x = 2 or x = –8

beks73 [17]

Answer:

x = 8 or x = -2

Step-by-step explanation:

x^2 - 6x + 9 = 25

x^2 - 6x - 16 = 0

The formula to solve a quadratic equation of the form ax^2 + bx + c = 0 is equal to x = [-b +/-√(b^2 - 4ac)]/2a

with a = 1

b = -6

c = -16

substitute in the formula

x = [-(-6) +/- √(-6^2 - 4(1)(-16))]/2(1)

x = [6 +/- √(36 + 64)]/2

x = [6 +/- √10]/2

x = [6 +/- 10]/2

x1 = [6 + 10]/2 = 16/2 = 8

x2 = [6 - 10]/2 = -4/2 = -2

Y-1=2/3(x+9) in standard form

UNO [17]

First, distribute 2/3 to the values in the parentheses. This gives you y-1=2/3x+6.

To get y alone, we add 1 to both sides. This gets you y=2/3x+7.

y=mx+b
y=2/3x+7

It matches the standard form, so your final answer would be y=2/3x+7.

An environmental (soil) sample obtained from a temperate region was transferred to a liquid growth medium and incubated at 30°C

ad-work [718]

Missing Question:

The question was missing information. I have found the question online and attaching it here for convenience.

Answer:

Option D

Explanation:

From the picture, we can see two types of bacteria (i.e. A and B), therefore it is not a pure culture.

We can not predict whether any culture has been lost during incubation.
A and B are different organisms.

Hence, the only correct option is D, which states:

"Identification of microbial types in the environmental sample could have been attempted without culturing anything."

What is a formula for the nth term of the given sequence?<br> 36, 24, 16...

SpyIntel [72]

Answer:

The formula to find the nth term of the given sequence is 54 · $\frac{2}{3} ^{n}$

Step-by-step explanation:

The formula for nth term of an geometric progression is :

$a_{n} = \frac{a_{1}(r^{n})}{r}$

In this example, we have $a_{1}$ = 36 (the first term in the sequence) and

r = $\frac{2}{3}$ (the rate in which the sequence is changing).

Knowing what the values for r and $a_{1}$ are, now we can solve.

$a_{n} = \frac{a_{1}(r^{n})}{r}$ = $\frac{36 (\frac{2}{3} ^{n}) }{\frac{2}{3} }$ = 54 · $\frac{2}{3} ^{n}$

Therefore, the formula to find the nth term of the given sequence is

54 · $\frac{2}{3} ^{n}$
