Answer:
the ball reaches a height of 64 feet after 2 sec.
The ball is in the air 4 sec.
Step-by-step explanation:
The ball is following the path of a parabola. The maximum height is at the vertex of the parabola.
Let (h, k) be the vertex. h will be the time it takes to reach the maximum height, and k will be that height.
y = [tex]-16t^{2} + 64t[/tex]
h = -b/2a = 64/(-2)(-16) = 64/32 = 2
k = -16(2)^2 + 64(2)
-16(4) + 128
- 64 + 128 = 64
V: (2, 64)
So the ball reaches a height of 64 feet after 2 sec.
Let [tex]-16t^{2} + 64t[/tex] = 0 (0 is the height when the balls hits the ground)
-16t(t - 4) = 0
t = 0 or t = 4
The ball is in the air 4 sec.

Answer:
70 degrees
Step-by-step explanation:
Angles 130 degrees and TUV are supplementary angles. Thus, the latter is (180 - 120), or 60, degrees. Now the sum of all three interior angles of this triangle must be 180 degrees: (60 + 50 + >TUV) = 180, so >TUV is 70 degrees (answer C).

how do I convert 3y - 15x +45 = 0 to both standard and slope-intercept form.
Answer:
https://www.khanacademy.org/math/cc-eighth-grade-math/cc-8th-linear-equations-functions/8th-slope/v/converting-to-slope-intercept-form
Step-by-step explanation:
Answer:
Step-by-step explanation:
Standard is ax + by = c so
3y - 15x +45 = 0
-15x + 3y = -45 <------- standard form
Slope intercept is y = ax + b
3y - 15x + 45 = 0
3y = 15x - 45
Divide through by 3:
y = 5x - 15. <---- Slope.intercept.

Answer:
7+4i+9+5i-2-5i
7+4i+9-2
4i+7+9-2
4i+14
Answer: 14 + 4i
Step-by-step explanation:
(7 + 4i) + (9 + 5i) - (2 + 5i)
Group the real part and the imaginary part of the complex number
(a + bi) ± (c + di) = (a ± c) + (b ± d)i
(7 + 9 - 2) + (4 + 5 - 5)i
7+9-2=14 and 4+5-5=4
Therefore, (7+4i)+(9+5i)-(2+5i) is equal to 14 + 4i

The expression -x^2 + 70x -600 represents a companys profit for selling x items. For which number of items sold is the companys profit equal to zero?
Answer:
Step-by-step explanation:
-x² + 70x - 600
If we multiply all by -1, we have
x² - 70x + 600
If we factorise this, we have
x² - 10x - 60x + 600
x(x - 10) - 60(x - 10)
(x - 10) (x - 60)
x = 10
x = 60
If the company sells 10, or 60 items, their profit is 0
which of the following is equivalent to the expression above
c) 2x^2y + 2xy^2
Explanation:
(x^2 y-3y^2+5xy^2)- (-x^2y+3xy^2-3y^2)
(x^2 y+5xy^2 -3y^2)- (-x^2y+3xy^2-3y^2)
x^2 y +5xy^2 -3y^2 + x^2y -3xy^2 + 3y^2
2x^2y + 2xy^2
The option C) 2x²y + 2xy² is equivalent to the given expression (x²y - 3y² + 5xy²) - (-x²y + 3xy² - 3y²).
Mathematically, an expression is an admixture of numbers, variables, operations, and functions that are conjoined according to peculiar rules to depict a mathematical calculation or association. It can be supposed to as a mathematical idiom or formula.
By combining numbers, variables, operators, and functions, mathematical expressions can define a broad lea of calculations and associations.
The given expression is (x²y - 3y² + 5xy²) - (-x²y + 3xy² - 3y²).
(x²y - 3y² + 5xy²) - (-x²y + 3xy² - 3y²)
= x²y - 3y² + 5xy² + x²y - 3xy² + 3y²
= 2x²y + 2xy².
Hence, option C) is correct in that 2x²y + 2xy² is equivalent to the given expression.

12x • 3x this is for my math class the dot means to multiply
Answer:
36x^2 or 36 times x squared.
Step-by-step explanation:
If x was two it would equal 144. If you replace x with two in my simplification it also equals 144.
Step-by-step explanation:
Here we will do more than give you the solution to 12x × 3x. We will also explain and teach you how we came up with the answer, so you can understand it and solve similar problems in the future without help.
In this problem, 12 and 3 are the coefficients and two Xs are the variables. When a coefficient is next to a variable there is an invisible multiplication sign. So you could rewrite the problem as follows:
12 × x × 3 × x =
So now you can multiply what are the same. You can multiply the coefficients together and the x variables together as follows:
12 × 3 = 36
x × x = x²
Then you put the answers together and make the multiplication sign invisible again to get the following answer:
12x × 3x = 36x²

[SLC 2068 B]
6B
Answer:
60,000
Step-by-step explanation:
Let us represent:
Costs price = x
Selling price = x - 25%x
x - 0.25x
= 0.75x
If it been sold for Rs 21,000 more then the profit would have been
10%. = x + 10% = 1.1x
1.1x =0.75x + 21000
Collect like terms
1.1x - 0.75x = 21000
0.35x =21000
x = 21000/ 0.35
x = 60000
The cost price of the item = 60,000

If X = 9 units, Y = 5 units, Z = 21 units, and h = 9 units, what is the surface area of the triangular prism shown above?
Answer:
Surface area of triangular prism = 528
Step-by-step explanation:
Surface area of triangular prism = (Base x Height) + 2 (length x side) + (length x base)
SA = bh + 2Ls + Lb
Putting given values : b = Y = 5 , h = 9 , s = x = 9 , L = z = 21
(5 x 9) + (2 x 21 x 9) + (21 x 5)
= 45 + 378 + 105
