Which equation represents a slope of 4 and (5,-2)?
y-2=4(x-5)
y-5=4(x-2)
y+2=4(x+5)
y+2=4(x-5)
Answer:
Step-by-step explanation:
the formula is named the point slope formula for a reason. and you have show both of them in the question , the slope and the point are given
y - y1 = m(x-x1)
so for your answer
y-(-2) = 4(x-5)
y+2 = 4(x-5) is the right answer

How to round 8.6023 in the nearest tenth?
Answer:
8.6
Step-by-step explanation:
https://www.you.tube.com/watch?v=32gDF10ZXOA
( it might be wrong pls dont report me just let me kno y its wrong )
Answer:
8.6
Step-by-step explanation:
First of all consider the thousands in the decimal which is 2. Since 2 is not greater than 5 we have to remove the number 2 and 3 from the 8.6023.
We're left with 8.60. Now we see that there's a 0 in the hundredths so since it's not greater than 5 we remove it.
Now we're left with 8.6 which is to the nearest tenth.

-6 x (1/3 + 1/3)What is the answer?
Answer:
−4
Step-by-step explanation
Answer:
−4
Step-by-step explanation:
-6 x (1/3 + 1/3)
Since 1/3 and 1/3 have the same denominator, add them by adding their numerators.
-6 x (1+1/3)
Add 1 and 1 to get 2.
-6 x (2/3)
Express -6 x (2/3) as a single fraction.
-6 x 2/3
Multiply −6 and 2 to get −12.
-12/3
Divide −12 by 3 to get −4.
−4
A ball is thrown into the air with an upward velocity of 44 ft/s. It’s height h in feet after t seconds is given by the function h=-16t^2 +44t+5. How long does it take the ball to reach its maximum height? What is the balls maximum height?
9514 1404 393
Answer:
1.375 seconds35.25 feetStep-by-step explanation:
A quadratic function y=ax^2 +bx +c is symmetric about the vertical line x=-b/(2a). That is the x-coordinate of the vertex (maximum or minimum).
Here, we have ...
h = -16t^2 +44t +5
t = -44/(2(-16)) = 11/8 = 1.375
It takes 1.375 seconds for the ball to reach its maximum height.
The height at that time is ...
h = (-16(11/8) +44)(11/8) +5 = (-22 +44)(11/8) +5 = 121/4 +5 = 141/4 = 35.25
The maximum height is 35.25 feet.

Determine whether each expression is equivalent to 100t^2-0.5t
Answer:
[tex]100^{t^{2}-0.5\cdot t}[/tex] is not equivalent to [tex]\frac{10^{t^{2}}}{100^{t}}[/tex].
[tex]100^{t^{2}-0.5\cdot t}[/tex] is not equivalent to [tex]\frac{50^{t^{2}}\cdot 2^{t^{2}}}{25^{0.5\cdot t}\cdot 4^{0.5\cdot t}}[/tex].
[tex]100^{t^{2}-0.5\cdot t}[/tex] is not equivalent to [tex]\frac{50^{t^{2}-0.5\cdot t}}{5^{t^{2}-0.5\cdot t}}[/tex].
Step-by-step explanation:
The expression to be evaluated is [tex]100^{t^{2}-0.5\cdot t}[/tex], we find by algebraic means the equivalent expression:
Possibility 1:
[tex]100^{t^{2}-0.5\cdot t}[/tex]
[tex]\frac{100^{t^{2}}}{100^{0.5\cdot t}}[/tex]
[tex]\frac{100^{t^{2}}}{(100^{0.5})^{t}}[/tex]
[tex]\frac{100^{t^{2}}}{10^{t}}[/tex]
[tex]100^{t^{2}-0.5\cdot t}[/tex] is not equivalent to [tex]\frac{10^{t^{2}}}{100^{t}}[/tex].
Possibility 2:
[tex]100^{t^{2}-0.5\cdot t}[/tex]
[tex]\frac{100^{t^{2}}}{100^{0.5\cdot t}}[/tex]
[tex]\frac{(50\cdot 2)^{t^{2}}}{(25\cdot 4)^{0.5\cdot t}}[/tex]
[tex]\frac{50^{t^{2}}\cdot 2^{t^{2}}}{25^{0.5\cdot t}\cdot 4^{0.5\cdot t}}[/tex]
[tex]100^{t^{2}-0.5\cdot t}[/tex] is not equivalent to [tex]\frac{50^{t^{2}}\cdot 2^{t^{2}}}{25^{0.5\cdot t}\cdot 4^{0.5\cdot t}}[/tex].
Possibility 3:
[tex]100^{t^{2}-0.5\cdot t}[/tex]
[tex]\left(\frac{500}{5} \right)^{t^{2}-0.5\cdot t}[/tex]
[tex]\frac{500^{t^{2}-0.5\cdot t}}{5^{t^{2}-0.5\cdot t}}[/tex]
[tex]100^{t^{2}-0.5\cdot t}[/tex] is not equivalent to [tex]\frac{50^{t^{2}-0.5\cdot t}}{5^{t^{2}-0.5\cdot t}}[/tex].

Which scatterplot shows a linear association?
Answer:
A scatter plot shows the association between two variables. A scatter plot matrix shows all pairwise scatter plots for many variables. If the variables tend to increase and decrease together, the association is positive. If one variable tends to increase as the other decreases, the association is negative.

Need help ASAP!! What is the value of x?
Answer:
98
Step-by-step explanation:
the exterior angle is equal to the sum of the opposite interior angles
-Sumin <3
Answer:
98
Step-by-step explanation:
53+45+x = 180
53+45=98
180-98=82
82 (interior)
82+98=180
x = 98
What is the surface area and volume ?
6 pls literally. Begging
Answer:
180=144+3X
X=12
Step-by-step explanation:
angles must add to 180
180=45+80+3X+19
gather like terms
180=144+3X
subtract
36=3X
divide
X=12
Answer:
X = 12
All triangles add up to 180* so we first need to add the angles
45 + 80 = 125
180 - 125 = 55
We need to have x contribute to the angle being 55*
3 + 19 = 22
55 - 22 = 33
3 x 12 + 19 = 55
x = 12

It is dinos birthday today. She is 9 years older than tyger. Altogether, their ages add up to 23 years. How old is dino?
Answer:
7
Step-by-step explanation:
Tyger = x
Dinos = x + 9
Total = 23
x + x+9 = 23
2x + 9 = 23
2x = 23 - 9
2x = 14
x = 14/2 = 7

Mr. Armstrong went to Target to buy four pairs of dress socks. There was a 30% off sale
on the socks, and his total bill before tax was $14. What was the price of each pair of socks
before the sale?
Answer: $5
Step-by-step explanation:
We should note that since there was a 30% off sale, it means that he paid for 70% (100% - 30%) of the sales price.
Therefore, let the price of the socks be represented as x.
70% of x = 14
70/100 × x = 14
0.7 × x = 14
0.7x = 14
x = 14 / 0.7
x = 20
Therefore, the price of the socks was $20. Since there are 4 pairs, each pair will be:
= $20 / 4
= $5
