Use Pascal's triangle to find the coefficient of the third term in the expansion of (a + b)2.
Question 10 options:
A)
3
B)
1
C)
4
D)
2
Answer:
B
Step-by-step explanation:
(a+b)^2
using Pascal triangle
1 1
1 2 1
1 3 3 1
so the third term in the expansion of (a+b)^2
we use
1 2 1
a^2 + 2ab+b
hence the coefficient of third term is 1
option B is collect
plz answer!!! only if correct.
Answer:
90°Step-by-step explanation:
Sum of angles in triangle equals to 180°
∠R = 180° - (∠S + ∠T)∠R = 180° - (29° + 61°) = 180° - 90° = 90°"18 less than the quotient of a number and -5 is at most -2"
Answer:
so......... what's the question?
Step-by-step explanation:
what fraction is equivalent to -3/7
A. 3/-7
B.-3/-7
C.-7/3
D.7/3
ALSO PLEASE SAY HOW I NEED TO EXPLAIN HOW ITS EQUIVALENT
Answer:
A
Step-by-step explanation:
It is equivalent because as along as only one has the negative sign, then it will still be negative. Both being negative makes it positive and flipping the fraction changes the value.
Answer:
A
Step-by-step explanation:
the negative sign is exchangeable between the denominator and numerator because positive multiplied or divided by a negative will aways be a negative
Solve the equation for x and find the restrictions on the variable. Ax + bx = c
Answer:
x = c/(A + b)
A + b ≠ 0

Should be pretty easy to answer, I just need a refresher. I forgot how to solve for triangles...
Answer:
25.734
Step of explanation:
tanjent =opposite/adjacent
cosine =adjacent /hypotenuse
sine =opposite /hypotenuse
this use tangent because the opposite number is there and we want to find adjacent
so t =opposite /adjacent
tan25 °=12/ a
a=12/tan25
=25.734

Step-by-step explanation:
The sum of all angles in a triangle is always 180.
So we can set up an equation
3/2x+1/2x+x= 180
3/2+1/2x+2/2x=180
3x+1x+2x=360
6x=360
x=60
12 is 20% of what number?
Answer:
60
Step-by-step explanation:
(x + y)3 - (x - y)3 when x = 2 and y=-1
Step-by-step explanation:
When x = 2 and y = -1,
(x + y)³ - (x - y)³
= (2 - 1)³ - [2 - (-1)]³
= (1)³ - (3)³
= 1 - 27
= -26.

A pitcher holds 3 liters of lemonade. If the contents of the pitcher are equally divided among 8 people, how much lemonade will each person receive?
Answer:
0.375 litres
Step-by-step explanation:
Given that:
Total amount of lemonade held by pitcher = 3 litres
Number of people in which lemonade is to be given equally = 8
Amount of Lemonade received by each person will be:
Total amount of lemonade / number of persons
3 litres / 8
= 0.375 litres
Each person receives 0.375 litres of lemonade

Write the equation of a line parallel to y=2x+2 that passes through the point (-1, -7)
Answer: y=2x-5
Step-by-step explanation:
To find the line that is parallel to y=2x+2, we know the slope must be 2. Parallel lines NEVER touch. That tells us that the slope must be 2. Now, all we have to do is to plug in the point to find the y-intercept.
-7=2(-1)+b [multiply]
-7=-2+b [add both sides by 2]
b=-5
With the y-intercept, we can find the parallel line.
y=2x-5
To meet peak energy demand, an electric power cooperative buys back electricity generated locally. They pay #0.07 per solar-powered kWh (kilowatt-hour). How much money does a school make when it sells back 956 kWh to the cooperative?
Answer: #66.92
Step-by-step explanation:
Since the cooperative pays pay #0.07 per solar-powered kWh (kilowatt-hour), the amount that the school would make when it sells back 956 kWh to the cooperative would be calculated as:
= #0.07 × 956 kWh
= #66.92
If you have 5000 per 125 mcg and need 7140 how many mcg do you need?
Answer:
178.5mcg
Step-by-step explanation:
If you need 5000 per 125mcg, we can express it as;
5000 = 125mcg
To get the amount of mcg needed for 7140, we will say;
7140 = x mcg
Divide both expression
5000/7140 = 125/x
Cross multiply
5000x x= 7140 * 125
5000x = 892,500
x = 892,500/5000
x = 178.5
Hence the amount og mcg needed is 178.5mcg

What is
[tex] 6 \frac{1}{3} \div \frac{1}{6} [/tex]
equal to?
options:
A. 6
B. 9
C. 12
D. 19
E. 38
Answer:
The answer is E, 38.
Step-by-step explanation:
6×1/3 can be written as 19/3.
Use the reciprocal of 1/6, which is 6, and multiply 19/3 and 6.
6 and 3 can be simplified with 2.
So: 19 × 2, which is 38.
