Answer:
2[tex]\sqrt{13}[/tex]
Step-by-step explanation:
Use the distance formula and plug in the values
d=(3−(−3))2+(2−6)2√
d=(6)2+(−4)2√
d=36+16√
d=[tex]\sqrt{52}[/tex]
d= 2[tex]\sqrt{13}[/tex]

Step-by-step explanation:
sin 14°=x/40
=> sin 14° X 40 = x
∴ x = 9.67≈ 9.7
Using the change-of-base formula, which of the following is equivalent to the
logarithmic expression below?
log, 18
Given:
The logarithmic expression is:
[tex]\log_718[/tex]
To find:
The equivalent expression of given expression by using change-of-base formula.
Solution:
The change-of-base formula is:
[tex]\log_ba=\dfrac{\log_ca}{\log_cb}[/tex]
The given expression is:
[tex]\log_718[/tex]
Using the change-of-base formula, we get
[tex]\log_718=\dfrac{\log_c18}{\log_c7}[/tex]
Where, is a constant and c>0.
Let [tex]c=10[/tex], then
[tex]\log_718=\dfrac{\log_{10}18}{\log_{10}7}[/tex]
Therefore, the correct option is a.

Please help what is the are of the triangle!!
Answer: B
Step-by-step explanation:
the formula for area of a triangle is base times height divided by 2
to get the base do 12.3 x 2 = 24.6
24.6 x 25.6 = 629.76
629.76/2 = 314.88
the answer would be B
(sorry for saying the answer was A at first, i forgot to find the full base)
Answer:
B. 314.9m
Step-by-step explanation:
First, let's take a look at the formula of a triangle.
A=[tex]\frac{1}{2}[/tex](b * h) ALSO WRITTEN AS- A= [tex]\frac{(b*h)}{2}[/tex].
So, as you can see, there is only half the base provided. To get the other half, just multiply it by 2. You get 24.6m as the base.
The height is provided. It's 25.6m. Plug in your base and height values and slove.
A=[tex]\frac{24.6m * 25.6m}{2}[/tex]
A= [tex]\frac{629.76}{2}[/tex]
A= 314.88m
You then round to the nearest tenth.
The final answer is A=314.9m.

Simra cuts an 8-carat diamond into smaller pieces. If each piece of diamond is 1/3 carat, how many pieces of diamond does Simra have now?
Answer: 24
Step-by-step explanation:
Given
Simra has an 8-carat diamond
She cuts small pieces of [tex]\frac{1}{3}[/tex] carat
Suppose she cuts x pieces of diamond
[tex]\therefore x=\dfrac{8}{\frac{1}{3}}\\\\\Rightarrow x=8\times 3\\\Rightarrow x=24[/tex]
She has now 24 pieces of diamond.
Solve the equation x2 – 10x – 8= 0 to the nearest tenth.
Answer:
x = -0.8 and 10.8
Step-by-step explanation:
Given the equation x2 – 10x – 8= 0
Using the general formula
x = -b±√b²-4ac/2a
x = -(-10)±√(-10)²-4(1)(-8)/2(1)
x = 10±√100+32/2
x =10±√132/2
x = 10±11.489/2
x = 10-11.489/2 and 10+11.489/2
x = -1.489/2 and 21.489/2
x = -0.8 and 10.8

4. Solve 18 (c – 19) = 108. Show your steps
Answer:
c = 25
Step-by-step explanation:
First, you can divide by 18 on both sides:
18 (c - 19) = 108
÷ 18 ÷18
c - 19 = 6
To isolate the variable c, you can add 19 on both sides:
c - 19 = 6
+19 +19
c = 25
Answer:
c= 25
Step-by-step explanation:
108/18 = 6
6 +19 = 25

If cos A = 1/2, then what is the positive value of cos 1/2 A, in simplest radical form with a rational denominator?
Answer:
[tex]\cos(\frac{1}{2}A) = {\frac{\sqrt{3}}{2}[/tex]
Step-by-step explanation:
Given
[tex]\cos A = \frac{1}{2}[/tex]
Required
Determine [tex]\cos(\frac{1}{2}A)[/tex]
To do this, we make use of the following identity
[tex]\cos(\frac{1}{2}A) = \sqrt{\frac{\cos A+1}{2}}[/tex]
Substitute: [tex]\cos A = \frac{1}{2}[/tex]
[tex]\cos(\frac{1}{2}A) = \sqrt{\frac{\frac{1}{2}+1}{2}}[/tex]
Solve the numerator
[tex]\cos(\frac{1}{2}A) = \sqrt{\frac{\frac{2+1}{2}}{2}}[/tex]
[tex]\cos(\frac{1}{2}A) = \sqrt{\frac{\frac{3}{2}}{2}}[/tex]
Rewrite as:
[tex]\cos(\frac{1}{2}A) = \sqrt{\frac{3}{2} * \frac{1}{2}}[/tex]
[tex]\cos(\frac{1}{2}A) = \sqrt{\frac{3}{4}}[/tex]
Take square roots
[tex]\cos(\frac{1}{2}A) = {\frac{\sqrt{3}}{2}[/tex]

Answer:
361 tiles
Step-by-step explanation:
Answer:
361 1-ft square tiles.
Step-by-step explanation:
The area of the room is a square. It has the same length on each side.
To find how many square tiles you need to cover the floor of the room you need to find the area.
Squares are easy to find the area of because you only need to multiply both sides by each other.
19x19=361
To multiply easier, you can 19 by 10 which equals 190.
Then you can add.
190+190
100+100=200
90+90=180
200+180=380
380-19=361

Carla is a waitress at Daybreak Diner and she earns $5 for each hour she works. Last week she earned 148 total including $68 tips how many hours did Carla work last week
Answer: 16 hours
Step-by-step explanation:
Given
Carla earns [tex]\$5[/tex] for each hour she works
Last week she earned $148 total including [tex]\$68[/tex] tip
So, the sum of hourly income and must be equal to the total money earned
Suppose she works for [tex]x[/tex] hours
[tex]\Rightarrow 5x+68=148[/tex]
[tex]\Rightarrow 5x=148-68\\\Rightarrow 5x=80\\\Rightarrow x=16\ \text{hours}[/tex]
Thus, she works 16 hours last week
Write an algebraic equation for the following. Do NOT solve:
7 less than p is 42
Answer:
p - 7 = 42
Step-by-step explanation:
"Less than" might make you think of the < sign, but that's a mistake. The expression 7 < p = 42 makes no sense! In fact, that would say, "7 is less than p and p = 42."
To find 7 less than a number, you subtract 7 from the number. You start with the number, then subtract 7.
p - 7 = 42

Mike saves $42 a week for 7 weeks. During his 8-day vacation, he plans to spend $8.25 each day for snacks. Which expression shows how much money he will have left?
Answer:
($42 × 7) - ($8.25 × 8)
Step-by-step explanation:
Given that
Mike saves $42 a week for 7 weeks
And, his 8 day vacation, he plans to spend $8.25 each day
We need to find out the expression of how much he would have left
So,
Since the amount $42 is for a week
So for 7 weeks, it would be
= $42 × 7
And, he spends $8.25 each day,
And, for 8 days, it would be
= $8.25 × 8
So, the expression is
= ($42 × 7) - ($8.25 × 8)

Which angles are represented by the same point on the unit circle as pi/4 ?
Answer:
d) [tex]\frac{9\pi }{4}[/tex]
Step-by-step explanation:
[tex]\frac{9\pi }{4} = 2\pi + \frac{\pi }{4}[/tex]
The correct options are a and d because -7pi/4 and 9pi/4 are the required angles.
Important infromation:
The given angle is [tex]\dfrac{\pi}{4}[/tex].Angles:The angles [tex]\theta\pm 2n\pi [/tex] represent the same point on the unit circle as [tex]\theta[/tex].
It means, [tex]\dfrac{\pi}{4}\pm 2n\pi [/tex] represents the same point on the unit circle as [tex]\dfrac{\pi}{4}[/tex].
The required angles are:
[tex]\left\{...,\dfrac{\pi}{4}-4\pi,\dfrac{\pi}{4}-2\pi, \dfrac{\pi}{4},\dfrac{\pi}{4}+2\pi,\dfrac{\pi}{4}+4\pi,...\right\}[/tex]
[tex]\left\{...,-\dfrac{15\pi}{4},-\dfrac{7\pi}{4}, \dfrac{\pi}{4},\dfrac{9\pi}{4},\dfrac{17\pi}{4},...\right\}[/tex]
Therefore, the correct options are a and d.
