The point (2,9) undergoes a translation given by (x,y) (x+3,y-8) the new coordinate of the point is
Answer:
(5 , 1)
Step-by-step explanation:
coordinate point is (2 , 9)
translation rule is
(x , y) = (x + 3 , y - 8)
here x is 2 and y is 9
so the new coordinate will be
(x + 3 , y - 8)
(2 + 3 , 9 - 8)

Show CLEARLY how you got your answers with reasons
Answer:
x = 152°
Step-by-step explanation:
∠ BDE = ∠ ABD = 76° ( alternate angles )
Since DE = BE then Δ BDE is isosceles with base angles congruent
∠ DBE = ∠ BDE = 76°
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
x is an exterior angle of the triangle, then
x = 76° + 76° = 152°

A. 3.7
B. 4.4
C. 8.9
D. 4.2
Answer:
C 8.9
Step-by-step explanation:
all these lines (from the same point of origin, cutting into and through a circle, ending at the far end of the circle they are cutting into) have the same relation of their lengths :
a×(a+b) is the same for all these lines.
with a being the first segment from the point of origin to touching the outside of the circle, and b being the length of the line inside the circle.
so,
4×(4+16) = 8×(8+2) = 80
this is correct for these two lines.
now, the line with the length x is a special case, as it does not really go through a circle, it only touches them.
but the length relation applies also to this line. it is just that the length inside the circle is 0.
so,
x×(x+0) = 80 (the same value as for the other lines)
must be true here too.
=>
x² = 80
x = sqrt(80) ≈ 8.9

OK, so I was learning about how to factorize a quadratic polynomial. And I also wrote notes on it. Now, even though I know that my notes are definitely correct, I’m getting stuck at a certain point. Please look at the attached photo, and explain why the variable X and the number 4 have been removed when we get the factors. I’d greatly appreciate it. Thanks!
Answer:
so when factorising, you first remove the common factors. in this case it is (x+3)
so what is remaining is the x and 4
you group that together.
my teacher explained that when factorising, after removing the common factor then you divide each term by the common factor, and then group the answers to that in brackets.
so it will be,
[tex]x(x + 3) + 4(x + 3) \\ (x + 3)( \frac{x(x + 3)}{x + 3} + \frac{4(x + 3)}{(x + 3)} [/tex]
so basically whats left after dividing, is x and 4 because the x+3 cancel off.
and thats how you get the answer of
(x+3)(x+4)
hope this helps;)

0.8 is the slope of the line M'N'.
What is the Linear equation?A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. Sometimes, the aforementioned is referred to as a "linear equation of two variables," with y and x serving as the variables.
So, the coordinates of M' are (0.82, 0.84) = (1.6, 3.2), and the coordinates of N' are (0.83, 0.85) = (2.4, 4).
Now, we can find the slope of line M'N' using the slope formula:
slope of M'N' = (y₂ - y₁) / (x₂ - x₁)
where (x₁, y₁) = (1.6, 3.2) and (x2, y2) = (2.4, 4).
slope of M'N' = (4 - 3.2) / (2.4 - 1.6)
the slope of M'N' = 0.8
Therefore, the slope of line M'N' is 0.8.

Find the measure of a single exterior angle of the regular polygon shown below. If necessary, round to the nearest tenth.
Answer:
32.7 degrees
Step-by-step explanation:
The total exterior angle of any polygon is 360 degrees
Each exterior angle can be calculated by dividing this total by the number of sides
So we have each measure as 360/n
where n is the number of sides
here, we have n = 11
So we have each exterior angle as:
360/11 = 32.7 degrees

A ball is thrown from an initial height of 4 feet with an initial upward velocity of 30 feet per second.
Answer:
I guess that we want to find the position equation for the ball.
First, we know that any object that is in the air has acceleration equal to the gravitational acceleration (where we ignore forces like air resistance and others) so we can write the acceleration equation as:
a(t) = -32 ft/s^2
Where 32 ft/s^2 is the gravitational acceleration, and the negative sign is because this acceleration is downwards.
To get the velocity equation, we can integrate over time to get:
v(t) = (-32 ft/s^2)*t + v0
where v0 is the initial velocity.
We know that the ball is thrown upwards with a velocity of 30 ft/s, then:
v0 = 30ft/s
And the velocity equation becomes:
v(t) = (-32 ft/s^2)*t + 30 ft/s
Finally, for the position equation we need to integrate again, to get:
p(t) = (1/2)*(-32 ft/s^2)*t^2 + (30 ft/s)*t + p0
where p0 is the initial position.
We know that the ball is thrown from an initial height of 4 ft, then:
p0 = 4ft
Then the position equation (or height equation) of the ball is:
p(t) = (1/2)*(-32 ft/s^2)*t^2 + (30 ft/s)*t + 4 ft
