Which number is closest to the
point on the number line?
A) -7/3
B) 16/11
C) 3/7
D) -5/5
Answer:
B. 16/11
Step-by-step explanation:
16/11 as a mixed number is 1 6/11. This is closest to 1 1/2 on the number line. The other negative numbers (-7/3, -5/5) are on the negative end on the spectrum so they are immediately eliminated. 3/7 doesn't have a whole number and therefore is not as close as 16/11 is to the point.

what is the vertex and y-intercept of y=-(x+3)^2+4
vertex: (−3, −4); y-intercept: 13
vertex: (3, −4); y-intercept: −9
vertex: (3, 4); y-intercept: −5
vertex: (−3, 4); y-intercept: −5
Answer:
Vertex → (x, y) = (− 3, − 4)
x intercepts → (x, y) = (−5, 0) and (−1, 0)
y intercept → (x, y) = (0, 5)
Step-by-step explanation:
Set y = 0 = ( x + 3)^2 − 4
Add 4 to both sides
4 = (x + 3)^2
Square root both sides
± 2 = x + 3
Subtract 3 from both sides
x = − 3 ± 2
x intercepts → (x, y) = (− 5, 0)
and
(− 1, 0)
You may if you so choose determine the vertex from this point
x vertex is midway between the x intercepts then by substitution determine y. The method I used later takes less work.
Given
y (x + 3)^2 − 4
x vertex = (-1) ×(+ 3) = − 3
y vertex = − 4
Vertex → (x, y) = (− 3, − 4)
y intercept = + 3^2 − 4 = 5

Hope it is helpful...Which of the following have one solution, solve for brainly :P
Answer:
C only
Step-by-step explanation:
C is the only one which is correct as in all the other options x is cancelled out as both sides have 2x which gets cancelled leaving the equation with something like:
31=31 which is true but it's not considered a "solution" and as A, B and D end up with stuff like this they are all not 1 solution. For c, as c doesn't have a power on top of it, like [tex]x^{2}[/tex] does, its equation can only have 1 solution (or in some cases 0 solutions but this isn't one of them) so it is the correct answer.
A. all real numbers
B. x = 0
C. all real numbers
D. no solutions

Answer:
AB ≈ 9.11
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan44° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{AC}{AB}[/tex] = [tex]\frac{8.8}{AB}[/tex] ( multiply both sides by AB )
AB × tan44° = 8.8 ( divide both sides by tan44° )
AB = [tex]\frac{8.8}{tan44}[/tex] ≈ 9.11 ( to 3 sf )
The product (-9 )x(-5) x(-6)x(-3) is positive whereas the product (-9)x(-5)x6 x(-3) is negative. Why?
Answer:
Answers below!
Step-by-step explanation:
-9 x -5 = 45
45 x - 6 = -270
-270 x -3 = 810
The answer is positive because a negative multiplied by a negative equals a positive number.
-9 x -5 = 45
45 x 6 = 270
270 x -3 = -810
This answer is negative because a negative multiplied by a positive equals a negative number.

Find the common ratio of the geometric sequence 6, 24, 96, ...
Answer:
The common ratio is 4
Step-by-step explanation:
How?
Multiplying or dividing is how to get the common ratio in a geometric sequence (moving from either left to right or right to left) *in this question to be precise* okay so...
Moving from right to left, and dividing, 96 ÷ 24 is 4; 24 ÷6 is 4 so the common ration is still 4.
(To find the next terms, moving from left to right, and multiplying, multiply the previous term by the common ration, so the next term after 96 is 96 × 4, which is 384, and you continue....)
You are very welcome and good luck :)

X=14
X=28
X=67
X=37
Answer:
x = 28
Step-by-step explanation:
3x - 21 = 63, I am making them equal to each other because of the vertical angle theorem.
3x - 21 = 63, add 21 to both sides
3x = 84, divide 3 to both sides to make x by itself
x = 28

Manchu has drawn a
rectangle with a base of
24 cm and an area of
336 cm². He cuts the
rectangle as shown to make two triangles.
What are the height and area of each
triangle?
Answer:
Height of each triangle: 14cm
Area of each triangle: 168cm²
Step-by-step explanation:
So we know that the base of the area is 24. Lets find the height.
336 ÷ 24 = 14
If he makes two triangles out of the rectangle that just means he cuts it in half.
To find the area of one triangle lets do:
336 ÷ 2 = 168
Let's double check our answer:
(14 × 24) ÷ 2 = 168

Mark invests $1500 in an account that pays 5.7% interest compounded continuously. Assuming no deposits or withdrawals are made, how much money will be in the account after 10 years?
Answer:
$2,611.21
Step-by-step explanation:
A = P(1 + r/n)^nt
A = 1500(1 + 0.057/1)¹⁰
A = 1500(1.057)¹⁰
A = 1500(1.740803988528..)
A = 2611.205982792..
A ≈ $2,611.21
______________________
Where A is the total amount including interest, P is the initial amount or principle, r is the rate, n is how many times it is compounded per year, and t is the time in years.

Step-by-step explanation:
The mnemonic SOH CAH TOA is intended to remind you of the relations between trig functions and sides of a right triangle.
Here, we're given the side opposite the angle, and we want to find the side adjacent to the angle. The relevant trig function is ...
Tan = Opposite/Adjacent
Filling in the given values and solving for the adjacent side, we have ...
tan(35°) = 3/?
? = 3/tan(35°) . . . . . . multiply by ?/tan(35°)
? ≈ 4.28
