because when i take 5 in root, i have to multiply by itself and 3.
5√3 is can equal to √15.√5
because its already equal to √75

Find the first six terms of the sequence. a1 = 7, an = an-1 + 6
Answers
Answer:
7, 12, 17, 21, 26, 31
Step-by-step explanation:
The first term in the sequence is 7 we know this cause the first equation (a1 = 7) is telling us what the first term is. To find the next term we use the second equation (an = an - 1 + 6) we us the first term subtract 1 and then add 6 ( 7 - 1 = 6, 6 + 6 = 12) the second terms is 12. To find the rest of the terms we continue using the second equation but instead of with 7 this time we use 12 then the next time 17 then 21 then 26 so on and so forth.

Given that f(x) = x^3 + 2x^2 + 1, g(x) = −x^3 −x^2 −4x+ 4, h(x) = f(x) +g(x), and h(x) = 1, what is the value of x?
Answers
Answer:
x = 2
Step-by-step explanation:
h(x) = f(x) + g(x) = x³ + 2x² + 1 - x³ - x² - 4x + 4 ← collect like terms, thus
h(x) = f(x) + g(x) = x² - 4x + 5
Given
h(x) = 1, then
x² - 4x + 5 = 1 ( subtract 1 from both sides )
x² - 4x + 4 = 0 ← in standard form
(x - 2)² = 0 ← in factored form ( perfect square ), thus
x - 2 = 0 ⇒ x = 2
Quadrilateral ABCD is translated up and to the right and then rotated about point Q. Which congruency statement is correct?
Answers
Answer: B
Step-by-step explanation:
The congruency statement would be correct as ABCD ≅ ZYXW because the new triangle will be congruent to the original triangle when a triangle is translated.
What are congruent triangles?Two triangles are said to be congruent if their corresponding sides and angles are equal.
Given that Quadrilateral, ABCD is translated up and to the right and then rotated about point Q.
The following are the related points from the entire question:
Point A and point Z
Point B and point Y
Point C and point X
Point D and point W
This represents that:
Points A and Z are corresponding
Points B and Y are corresponding
Points C and X are corresponding
Points D and W are corresponding
Hence, the congruency statement would be correct as ABCD ≅ ZYXW because the new triangle will be congruent to the original triangle when a triangle is translated.

Answer:
47.5% of students fall within heights of 100 cm to 120 cm
Step-by-step explanation:
We are given that heights of Grade 1 students are normally distributed
Mean = [tex]\mu = 100 cm[/tex]
Standard deviation = [tex]\sigma = 10 cm[/tex]
a)
Empirical rule
68% of data lies within the first standard deviation from the mean i.e[tex].(\mu-\sigma , \mu+\sigma)=(100-10,100+10)=(90,110)[/tex]
95% of all the data will fall within two standard deviations i.e.[tex](\mu-2\sigma , \mu+2\sigma)=(100-2(10),100+2(10))=(80,120)[/tex]
99.7% of data lies within the three standard deviations i.e.[tex]( \mu - 3 \sigma , \mu +3 \sigma)=(100-3(10),100+3(10))=(70,130)[/tex]
b)Percentage of students fall within heights of 100 cm to 120 cm
Using the normal distribution curve
Percentage of students fall within heights of 100 cm to 120 cm = [tex]\frac{1}{2} \times 95\% = 47.5\%[/tex]
Hence 47.5% of students fall within heights of 100 cm to 120 cm

What is the area of this figure?
Answers
Answer:
11610
Step-by-step explanation:
First you do the top rectangle which the area for that is 144 which is 4 times 4 times 3 times 3.
Then you do the middle rectangle which the area is 441 which is 7 times 7 times 3 times 3.
Then you do the last rectangle which the area is 11025 which is 15 times 15 times 7 times 7.
Then lastly you add all three areas which is 144+441+11025=11610. So therefore, the answer is 11610.

If you multiply 235 by 49, what will be the partial products?
Answers
Answer:
Step-by-step explanation:
(200+30+5)(40+9)
40*200 = 8000
40*30= 1200
40*5=200
9*200= 1800

a =
b =
c =
d =
Answers
Answer:
a = -10
b = -5
c = -1008
d =-1000
Step-by-step explanation:
a = -30/3
b = 45/-9
c = -84x12
d = -88000/88
Answer: A = -10. B = 54. C = -1008. D = -1000
Step-by-step explanation:
a * 3= - 30 You must divide 3 on both sides in order to get the a alone.
a * 3/3= - 30/3 And once you divide 3 from both sides you end up with
a= -10 And a equals negative 10
-9 * b = 45 You have to add 9 to both sides to get b alone.
-9 +9 *b= 45 +9 And you end up with with
b= 54 b equals 54
-84 * 12= c Since the c is already alone all you have to do is solve the problem
-84 time 12 eqauls -1008, its a negative because it has a negative in the equation
-1008= c
d *88 = -88,000 You have to divide 88 from both sides to get the d alone.
d * 88/88 = -88,000/88. And you end up with
D = -1000 d equals negative 1000

Answer:
x = 20
Step-by-step explanation:
so we aren't give the angle across from 70, but we are given the degree on the outside, so if we take that and subtract it from 180 we will get the degree inside the triangle which is 70. (this also appears to be an isosceles triangle so it would be 70 anyway, but we can do this just to make sure.) Then, since all of the angles in the triangle add up to 180, we can subtract 140 (both 70 degrees) from it and we are left with 40. Divide 40 by 2 and you will get 20 which is the measure for angle x! Hope this helps

Answer:
1. 4 days
2. $1.2
3. 1 and 3 gallons
4. 15 and 10
16. 1.2 mi/h
-- Please refer to graph
-- Please refer to graph
Step-by-step explanation:
Solution 1.
Alex has $40, and Ellen has $24. Alex is saving $6 per day, and Ellen is saving $10 day.
Let x be the number of days in which they both have same money:
As per given statement:
[tex]40 + 6x=24+10x\\\Rightarrow 4x = 16\\\Rightarrow x =4[/tex]
In 4 days, they will have same money.
Solution 2:
Kendra owns a restaurant. She charges $6.00 for two eggs and one piece of toast and $3.60 for one egg and one piece of toast.
Let x be the price of one egg.
Let y be the price of one toast.
As per given statement:
[tex]2x+y=6 ...... (1)\\x+y= 3.6 ...... (2)[/tex]
Subtracting (2) from (1):
[tex]\Rightarrow x = \$2.4[/tex]
Price of toast = 3.6 - 2.4 = $1.2
Solution 3:
A restaurant has one type of lemonade that is 30% sugar and another that is 10% sugar. Resultant mixture 4 gallons of 15% sugar.
Let x be the amount of lemonade with 30% sugar.
Amount of another lemonade with 10% sugar = (4-x)
As per question statement:
[tex]x \times 30\% + (4-x) \times 10\% = 4 \times 15\%\\\Rightarrow x \times 30 + (4-x) \times 10 = 4 \times 15\\\Rightarrow 20x = 20\\\Rightarrow x = 1[/tex]
Lemonade with 30% sugar required is 1 gallon.
Lemonade with 10% sugar required is 3 gallons.
Solution 4:
A scientist has a container of 2% acid solution and a container of 5% acid solution. Resultant mixture is 25 fl oz of 3.2%.
Let x be the amount of 2% acid solution.
Amount of another lemonade with 5% acid solution = (25-x)
As per given question statement:
[tex]2\%\ of\ x + 5\% \ of\ (25-x) = 3.2\%\ of\ 25\\\Rightarrow 2x + 5(25-x)=3.2 \times 25\\\Rightarrow -3x = -1.8 \times 25\\\Rightarrow x = 15[/tex]
2% acid solution required is 15 fl oz.
5% acid solution required is 10 fl oz.
Solution 16:
Let v be the speed of river current.
Let u be the speed of kayaker.
As per question:
The speed of a kayaker is 5.75 mi/h paddling with the river current and 3.25 mi/h paddling against it.
[tex]u +v=5.75......(1)\\u-v = 3.25.....(2)[/tex]
Equation (1) - (2):
[tex]2v = 2.5\\\Rightarrow v = 1.25\ mi/h[/tex]
----------------------------------

What will happen to the graph of the line y = 3/4x – 7 if you change 3/4 to −3/4?
Answers
Answer:
Below.
Step-by-step explanation:
The slope is given by the coefficient of x (= 3/4) .
If the slope changes to -3/4 the line will slope in the opposite direction.
If the slope is 3/4(positive) it rises to the right and if it is -3/4 it will rise to the left, but will rise at the same rate.
The 2 lines will cross each other when 3/4x - 7 = -3/4x - 7:
3/4x - 7 = -3/4x - 7
6/4 x = 0
x = 0
So they will cross at the point (0, -7).
