Answer:
[tex] \cos( {x}^{2}y ) = {y}^{2} \\ \frac{d( \cos( {x}^{2}y) ) }{dx} = \frac{d( {y}^{2}) }{dx} \\ (2xy + {x}^{2} \frac{dy}{dx} ).( - \sin( {x}^{2} y) ) = 2y \frac{dy}{dx} \\ \frac{- 2xy \sin( {x}^{2}y ) - {x}^{2} \sin( {x}^{2} y) }{2y} = \frac{dy}{dx} \\ [/tex]
B.
If m ZACB = 180°, and mZACD = 55°, then
mZDCB = [?]
Enter
Answer:
125
Step-by-step explanation:
/_ ACB = 180
/_ ACD = 55
/_ ACB is made up of /_ACD and
/_ DCB
Hence, /_ ACB = /_ ACD + /_ DCB
*We then plug in the known values*
180 = 55 + /_ DCB
We now solve for the missing angle
Subtract 55 from both sides
125 = /_ DCB
I NEED HELP ASAP IM STRESSJNG OUT
Answer:
A
Step-by-step explanation:
Using the Sine rule in Δ ABC
∠ B = 180° - (30 + 50)° = 180° - 80° = 100° ( sum of angles in triangle ) , then
[tex]\frac{13}{sin100}[/tex] = [tex]\frac{BC}{sin30}[/tex] ( cross- multiply )
BC × sin100° = 13 × sin30° ( divide both sides by sin100° )
BC = [tex]\frac{13sin30}{sin100}[/tex] ≈ 6.6 ( to the nearest tenth )

Which function graph is shown
Answer:
A) y=3cos(-x)
Step-by-step explanation:
Because the amplitude of the graph is 3, this eliminates options C and D as their amplitudes are different. With the period of the graph being 2π, B cannot be correct because that would have a period of π/2. Therefore, A is correct.

A.-1/2
B.3
C.0.25
D.-1
Answer:
i got -2
Step-by-step explanation:
1 step; 8*x-5-(11)=0
2 step; 8x - 16 = 8 • (x - 2)
3 step; Solve : 8 = 0
4 step; Solve : x-2 = 0
final part Add 2 to both sides of the equation :
x = 2
what is the slope that passes through the points : (-2,9) and (4,-7)
Use the slope formula below:
[tex] \large \boxed{m = \frac{y_2 - y_1}{x_2 - x_1} }[/tex]
The m-term represents the slope.
The formula is the changes of two y-points over the changes of two x-points. We are given two points. Substitute both points in the formula.
[tex] \large{m = \frac{9 - ( - 7)}{ - 2 - 4} } \\ \large{m = \frac{9 + 7}{ - 6} \longrightarrow \frac{16}{ - 6} } \\ \large{m = \frac{8}{ -3 } \longrightarrow - \frac{8}{3} }[/tex]
Therefore the slope is -8/3
Answer
the slope is -8/3Hope this helps! Let me know if you have any doubts.
Answer:
y = -8 / 3x + 11/3
Step-by-step explanation:
Using the slope formula:
[tex]slope = y = \frac{(y_{2}-y_{1})}{(x_{2}-x_{1})}[/tex]
1. Select one point to be [tex](x_{1} ,y_{1} )[/tex] and the other [tex](x_{2} ,y_{2} )[/tex]
I chose (-2, 9) to be [tex](x_{1} ,y_{1} )[/tex] and (4, -7) to be [tex](x_{2} ,y_{2} )[/tex]
2. Plug the values into the formula:
[tex]y = \frac{-7-9}{4-(-2)} \\\\y= \frac{-16}{6} \\\\y = \frac{-8}{3}[/tex]
3. Finding the c-value by plugging in one of the points into the equation
y = mx + c
9 = -8/3 (-2) + c
9 = 16/3 + c
c = 11/3
4. y = -8/3x + 11/3

The graph shows the absolute value parent function. Which statement best describes the function?
A. The function is positive when x > 0.
B. The function is always positive.
C. The function is positive when x< 0 and when x > 0
D. The function is positive when x< 0
PLEASE HELPPP!!!!
The function of the absolute value is always positive the correct answer would be option (B).
What is a graph?A graph can be defined as a pictorial representation or a diagram that represents data or values.
What is absolute value?Absolute value is defined as the magnitude or size of a number, no negatives are allowed. The distance a number is from 0 on the number line is known as the absolute value of the number.
For example, |5| is 5 because it is 5 units away from 0. Also, |-5| is also 5 because -5 is 5 units from 0.
We have to determine the statement best describes the function.
We have been given that the graph represents the absolute value parent function.
Since the parent function's graph with an absolute value that is always positive.
Therefore, the graph of the absolute value parent function would be always positive.
Hence, the correct answer would be option (B)

Hikers' World Foods sells raisin-nut mix in bulk to stores. The dollar amount per pound, P(x), for a store to purchase x pounds of raisin-nut mix from Hikers World is given by the function below. P(x) = 3.50 + 0.90^x . To the nearest $0.01, which of the following dollar values is equal to the total price for a store to purchase 100 pounds of raisin-nut mix in a single order from Hikers World?
A. $350.00
B. $359.00
C. $440.00
D. $616.00
E. $903.50
Answer:
A. $350.00
Step-by-step explanation:
The expression for a store to purchase x pounds of raisin-nut mix is;
P(x) = 3.50 + [tex]0.90^{x}[/tex]
Where: P(x) is the dollar amount per pound, and x is the number of pounds bought.
The total price for the store to purchase 100 pounds can be determined by;
since the pounds of raisin-nut mix to be bought in a single order is 100, then x = 100.
So that;
P(x) = 3.50 + [tex]0.9^{100}[/tex]
= 3.5 + 0.000026561
P(x) = 3.500026561
Thus to the nearest $0.01, then;
P(x) = [tex]\frac{3.500026561}{0.01}[/tex]
= $350.0026561
P(x) = $350.00

Answer:
Jaden would have to save $25 each week for next 6 weeks to get the $290 bike.
Step-by-step explanation:
What do we know:
He has $140 to start withHe saves $25 each weekHis bike costs $290What are we solving for;
We are solving for x (number of weeks it would take Jaden to buy a $290 bike), when y = 290Equation would be:
y = 25x + 140So for Jaden to buy a $290 bike, y would have to be replaced with 290, and solve for x;
y = 25x + 140=> 290 = 25x + 140
=> 290 - 140 = 25x
=> 150 = 25x
=> 150 / 25 = x
=> 6 = x
Therefore, Jaden would have to save $25 each week for next 6 weeks to get the $290 bike.
Hope this help!

what is the mean absolute deviation for 3 3 4 5 5 4
Answer as a fraction = 2/3
Answer in decimal form = 0.667 (approximate)
=======================================================
Explanation:
The first thing we need is to find the mean. Add up the values to get 3+3+4+5+5+4 = 24. Then divide by n = 6 since there are 6 values.
24/n = 24/6 = 4
The mean is 4
Now subtract the mean from each value
3-4 = -13-4 = -14-4 = 05-4 = 15-4 = 14-4 = 0Apply absolute value to each result so that the difference is not negative.
We get this new list: {1, 1, 0, 1, 1, 0}
Now compute the mean of that new list to get the final answer
1+1+0+1+1+0 = 4
4/n = 4/6 = 2/3 = 0.667 approximately

LCM = 2 * 2 * 2 * 2 * 5 * 3 = 240
HCF = 2*2*5= 20
help me solve for m<4 and m<5 and x
Answer:
x = 18
Angle 4 = 31 degree
Angle 5 = 59 degree
Step-by-step explanation:
According to the question, angle 3 is 90 degree and the sum of angle 4 and 5 is equal to the angle 3 as they are vertically opposite angles.
Angle 4 + angle 5 = 90 degree
Angle 4 = 2 x - 5
angle 5 = 4 x - 13
So, according to the question,
2 x - 5 + 4 x - 13 = 90
6 x - 18 = 90
6 x = 108
x = 18
So, angle 4 = 2 (18) - 5 = 31 degree
So, angle 5 = 4 (18) - 13 = 59 degree

Help me to do exercise no 5
Answer:
Step-by-step explanation:
a) x + 20 = 70 Vertically opposite angles are congruent
b) 2x - 50 = x + 20 Vertically opposite angles are congruent
c) 3x - 10 + 140 = 180 Linear pair
Answer:
(a) 70= x+20 (vertical angles are equal)
70 - 20=x
50=x
(b) x +20 = 2x -50 (vertical angles are equal)
20 + 50 = 2x - x
70 = x
(c) 140 +3x -10=180 (angles on the straight line)
130 +3x = 180
3x = 180 - 130
3x = 50
x= 50/3
