Answer:
0.88 (I think this is how Mrs. Futch wants it to be written)
Step-by-step explanation:
h=-16t^2+14t
(Substitute h with 0)
0=-16t^2+14t
(Factor)
0=2t(-8t+7)
2t=0 -8t+7=0
t=0 t=0.88
{0, 0.88}
Answer:
So everyone here in Mrs. Futch?

The inverse, f'(x), of f(x) =
X + 5
Х
can be written as
5
x-1
a) Find f(2)
b) Find f'(2)
Step-by-step explanation:
Given
[tex]f(x) = \frac{x + 5}{x} [/tex]
So
[tex]f(2) = \frac{2 + 5}{2} \\ = \frac{7}{2} [/tex]
Now
[tex] {f}^{ - 1} (x) = \frac{5}{x - 1} [/tex]
So
[tex] {f}^{ - 1} (2) = \frac{5}{2 - 1} \\ = \frac{5}{ 1} \\ = 5[/tex]

15. Asriel thinks he has room for a 50 inch TV in his living room. It turns out
he only has room for a 40 inch TV. What is his percent error? *
10%
25%
20%
30%
Answer: 10%
Step-by-step explanation: because if you subtract 50-40 you get 10 and then you just add the % sign and you can cross out d and b.
hope this helps you
Answer:
20%
Step-by-step explanation:
Since, 40/50 is equal to 80/100 we can tell that the 2 are 80% close to eachother, but there is 20% difference!

3sin60°+xcos30°.tan45°=xcot30°
Answer:
x = (6[tex]\sqrt{2}[/tex])/(4[tex]\sqrt{2}[/tex] -3)
Step-by-step explanation:
sin60 degree = [tex]\sqrt{3}[/tex] /2
cos30 degree = 1/2
tan 45 degree = sin45 degree / cos45 degree = ([tex]\sqrt{2}[/tex]/2)/([tex]\sqrt{2}[/tex] /2) = 1
cot 30 degree = cos30 / sin30 = ([tex]\sqrt{3}[/tex] /2)/(1/2) = [tex]\sqrt{3}[/tex]
so, let us plug the above values in the given eqution and solve for x
3([tex]\sqrt{3}[/tex] /2 ) + x(1/2) *1 = x([tex]\sqrt{3}[/tex])
3([tex]\sqrt{3}[/tex] /2 ) = x([tex]\sqrt{3}[/tex]) -x(1/2)
3([tex]\sqrt{3}[/tex] /2 ) = x(([tex]\sqrt{3}[/tex])-(1/2)) (by taking x as a common factor)
3([tex]\sqrt{3}[/tex] /2 ) = x(((2[tex]\sqrt{3}[/tex])-(1))/2)) (making the same common denominator
now devide both sides by (((2[tex]\sqrt{3}[/tex])-(1))/2))
x = 3([tex]\sqrt{3}[/tex] /2 ) / (((2[tex]\sqrt{3}[/tex])-(1))/2))
x = 3([tex]\sqrt{3}[/tex] ) / ((2[tex]\sqrt{3}[/tex])-(1))

Answer:
A) AA similarity
Step-by-step explanation:
AA stands for "angle, angle" and means that the triangles have two of their angles equal.
SAS stands for "side, angle, side" and means that we have two triangles where the ratio between two sides is the same as the ratio between another two sides and we we also know the included angles are equal.
SSS stands for "side, side, side" and means that we have two triangles with all three pairs of corresponding sides in the same ratio.
Here we can easily see that two angles are equal
∠CYK and ∠KZP∠CKY and ∠PKZ (they're cross angles)Therefore it's AA similarity

NUMBER: 17 SQUARE: 289 SQUARE ROOT: 4.123
Hope this helps a little.
Answer:
a. 4 and 5
Step-by-step explanation:
We are given 17 squared, and are asked on whether which of it is between the following pairs.
Squaring a number always gives it a smaller number since you are trying to find a number times itself to make the number in the square root.
Therefore by this knowledge, a. would be the most reasonable answer, since 17 is quite a small number, squaring it will equal something smaller.
(8x + 9) + (–6x – 1)
Answer:
5
Step-by-step explanation:
Simplifying
(8x + 9) + -1(6x + -1) = 0
Reorder the terms:
(9 + 8x) + -1(6x + -1) = 0
Remove parenthesis around (9 + 8x)
9 + 8x + -1(6x + -1) = 0
Reorder the terms:
9 + 8x + -1(-1 + 6x) = 0
9 + 8x + (-1 * -1 + 6x * -1) = 0
9 + 8x + (1 + -6x) = 0
Reorder the terms:
9 + 1 + 8x + -6x = 0
Combine like terms: 9 + 1 = 10
10 + 8x + -6x = 0
Combine like terms: 8x + -6x = 2x
10 + 2x = 0
Solving
10 + 2x = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-10' to each side of the equation.
10 + -10 + 2x = 0 + -10
Combine like terms: 10 + -10 = 0
0 + 2x = 0 + -10
2x = 0 + -10
Combine like terms: 0 + -10 = -10
2x = -10
Divide each side by '2'.
x = -5
Simplifying
x = -5

Pls help its my last question?!?!
Answer:
x = -11
m<B = -43
m<C = -22
Step-by-step explanation:
To solve for x, solve (3x-10) + (2x) + 65 to get 5x+55. Simplify to 5x = -55. This can simplify further to x = -11. Insert -11 as x into the angles.
I hope this is correct and helps!
Stacy reasons that since dilations change lengths they also change angles by the same factor. Is she correct? If not, explain why, I will list brainlist if you reply fast
Answer:
Stacy is incorrect. Dilations do not affect the angles of a given figure since dilations create parallel lines and the angles on parallel lines are congruent.

14d - 22 + 5d = 12d - 8
Answer:
d = 2
Step-by-step explanation:
14d - 22 +5d = 12d - 8
19d -22 = 12d - 8
+22 +22
19d = 12d + 14
-12d -12d
7d = 14
/7 /7
d = 2
Answer:
d = 2
Step-by-step explanation:
Simplifying
14d + -22 + 5d = 12d + -8
Reorder the terms:
-22 + 14d + 5d = 12d + -8
Combine like terms: 14d + 5d = 19d
-22 + 19d = 12d + -8
Reorder the terms:
-22 + 19d = -8 + 12d
Solving
-22 + 19d = -8 + 12d
Solving for variable 'd'.
Move all terms containing d to the left, all other terms to the right.
Add '-12d' to each side of the equation.
-22 + 19d + -12d = -8 + 12d + -12d
Combine like terms: 19d + -12d = 7d
-22 + 7d = -8 + 12d + -12d
Combine like terms: 12d + -12d = 0
-22 + 7d = -8 + 0
-22 + 7d = -8
Add '22' to each side of the equation.
-22 + 22 + 7d = -8 + 22
Combine like terms: -22 + 22 = 0
0 + 7d = -8 + 22
7d = -8 + 22
Combine like terms: -8 + 22 = 14
7d = 14
Divide each side by '7'.
d = 2
Simplifying
d = 2
3. The point P(3,5) is rotated 90° clockwise
about the origin. What are the coordinates of
P'?
A. P'(-3,-5)
B. P’(5,-3)
C. P'(-5,3)
D. P'(5, 3)
Please :)
Answer:
New coordinates of P' are: P'(5, -3)
Hence, option B i.e. P'(5,-3) is correct.
Step-by-step explanation:
When a point A(x, y) is rotated 90° clockwise around the origin, we flip x and y and reverse the sign of x.
Thus,
The rule to rotate a point A(x, y) after a rotation 90° counterclockwise around the origin is:
A(x, y) → A'(y, -x)
In our case, the point P(3, 5) is rotated 90° clockwise about the origin. Thus, the coordinates of P' will be:
A(x, y) → A'(y, -x)
P(3, 5) → P'(5, -3)
Therefore, coordinates of P' are: P'(5, -3)
Hence, option B i.e. P'(5,-3) is correct.

find the measure of angle A
Answer:
35 degrees
Step-by-step explanation:
Sum of angles inside a triangle is 180 degrees.
Right angle is 90 degrees.
180 = 90 + (x + 46) + (x + 66) = 2x + 202
x = -11
A = x + 46 = -11 + 46 = 35

What is mz2?

ОООО
67°
740
Answer:
m∠2 = 67°Step-by-step explanation:
m║n ⇒ (9x + 2)° = 74° {Corresponding Angles}
(9x)° = 72°
x = 8
Angles: angle corresponding to angle (5x-1)°, angle 74° and angle 2 add to 180° (straight angle)
(5×8 - 1)° + 74° + m∠2 = 180°
39° + 74° + m∠2 = 180°
113° + m∠2 = 180°
m∠2 = 180° - 113°
m∠2 = 67°
