Answer:
Option (4)
Step-by-step explanation:
By applying triangle sum theorem in ΔABC,
m∠A + m∠B + m∠C = 180°
80° + 40° + m∠C = 180°
m∠C = 180° - 120°
m∠C = 60°
Since, ∠ACB ≅ ∠DCE [Vertically opposite angles]
m∠DCE = m∠ACB = 60°
Now by applying triangle sum theorem in ΔCDE,
m∠DCE + m∠CED + m∠CED = 180°
60° + 70° + x° = 180°
x = 180 - 130
x = 50°
Therefore, Option (4) will be the answer.

One solution to a quadratic function, h, is given.
-4 + 7i
Which statement is true?
A. Function h has no other solutions.
B. The other solution to function h is -4 − 7i.
C. The other solution to function h is 4 − 7i.
D. The other solution to function h is 4 + 7i.
The answer isn't A. Function h has no other solutions.
I hope this helps.
Answer:
B. The other solution to function [tex]h[/tex] is [tex]-4-i\,7[/tex].
Step-by-step explanation:
From Algebra, we remember that quadratic functions of the form [tex]a\cdot x^{2}+b\cdot x + c[/tex] has solutions of the form:
[tex]x = \frac{-b\pm \sqrt{b^{2}-4\cdot a\cdot c}}{2\cdot a}[/tex], where both are complex if and only if [tex]\sqrt{b^{2}-4\cdot a \cdot c}< 0[/tex].
Hence, if one solution of the quadratic function is [tex]-4+i\,7[/tex], then the other solution is [tex]-4-i\,7[/tex]. The correct answer is B.

Select all the intervals where f is decreasing
One Answer: Choice C) 0 < x < 1
==================================================
Explanation:
Let's go through the answer choices one at a time.
Choice A represents an increasing interval since the graph goes uphill as we move from left to right. The line through the points (-2, f(-2)) and (-1.5, f(-1.5)) has a positive slope. We can rule out choice A.Choice B is a similar story to choice A. The graph goes uphill when we move from x = -1 to x = 0, so the graph is increasing on the interval -1 < x < 0. We can rule out choice B.In contrast, choice C is a decreasing interval. Going from x = 0 to x = 1 has us move downhill. Choice C is the only answer.Choice D is false because choice C was shown to be true.The correct option is C
What is a decreasing function?A function whose value decreases as the independent variable increases over a given range is called a decreasing function.
Considering the options :
A) it represents an increasing interval since the graph goes uphill as we move from left to right. The line through the points (-2, f(-2)) and (-1.5, f(-1.5)) has a positive slope. We can rule out choice A.
B) It is a similar story to choice A. The graph goes uphill when we move from x = -1 to x = 0, so the graph is increasing on the interval -1 < x < 0. We can rule out choice B.
In contrast, C is a decreasing interval. Going from x = 0 to x = 1 has us move downhill. Choice C is the only answer.
Hence, the correct option is 0 < x < 1

Express this rate as a unit rate: $50 for 4 days of work. Note: You must label your unit rate.
Answer:
12.50 dollars per day
Step-by-step explanation:
This is a fraction equal to
50 dollars ÷ 4 days
We want a unit rate where
1 is in the denominator,
so we divide top and bottom by 4
50 dollars ÷ 4
4 days ÷ 4
=
12.5 dollars

What is the best way to determine whether a given point is a solution to a system of equations?
A. Substitute the x and y coordinates into one equation and check to see if they work.
B. Graph the equations and see if the point lies on both lines
C. Substitute the x and y coordinate into both equations and check to see if they work
D. Solve the system of equations and compare the answer to the given point
Substitute the x and y coordinate into both equations and check to see if they work is a best way to determine whether a given point is a solution to a system of equations.
What is the system of equation?One or many equation having same number of unknowns that can be solved simultaneously called as simultaneous equation. And simultaneous equation is the system of equation.
The best way to determine whether a given point is a solution to a system of equations is to substitute the x and y coordinate into both equations and check to see if they satisfy the equation.
And if the solutions do not satisfy the equation that means given x , y are not the solutions.
And if the unknowns are the solutions of system of the equation that
means the pair of point lies in the graph.
Therefore the answer is option C.

if cos x = sin(20+x) degrees and 0 degrees < x < 90 degrees, the value of x is
Answer:
x = 35°
Step-by-step explanation:
From the question given above:
cos x = sin(20 + x)
The value of x can be obtained as follow:
cos x = sin(20 + x)
Recall:
sin(A + B) = sinAcosB + cosAsinB
Therefore,
sin(20 + x) = sin20cosx + cos20sinx
cos x = sin(20 + x)
cos x = sin20cosx + cos20sinx
Collect like terms
cos x – sin20cosx = cos20sinx
cos x(1 – sin20) = cos20sinx
Divide both side by cosx
(1 – sin20) = cos20sinx / cosx
Recall:
Tan x = sinx / cosx
(1 – sin20) = cos20tanx
Divide both side by cos20
(1 – sin20) / cos20 = tanx
(1 – 0.3420) / 0.9397 = tanx
0.658 / 0.9397 = tanx
0.7 = tanx
Take the inverse of tan
x = tan¯ 0.7
x = 35°

a. Angle D prime A prime B prime.
b. Angle A prime B prime C prime.
c. Angle B prime C prime D prime.
d. Angle C prime D prime A prime.
Answer:
D. <C'D'A'
Step-by-step explanation:
Given that figure ABCD is transformed to figure A′B′C′D′, therefore the angles of ABCD would be congruent to the corresponding angles of A′B′C′D′.
<CDA corresponds to <C'D'A'. Therefore:

Answer:
Answer is in attached image.
Step-by-step explanation:
Given the expressions, for which we have to find the estimates as per the expressions on the left.
The given expressions are:
1) 35 [tex]\times[/tex] 23
2) 132 [tex]\div[/tex] 168
3) 17.3 [tex]\times[/tex] 18.4
4) 999 [tex]\div[/tex] 208
5) 998 [tex]\times[/tex] 211
Here, we need to find the rounded off numbers.
35 can be rounded to 40 and 23 to 20.
Therefore, equivalent to 35 [tex]\times[/tex] 23 is 40 [tex]\times[/tex] 20
132 can be rounded to 130 and 168 to 170.
Therefore, equivalent to 132 [tex]\div[/tex] 168 is 130 [tex]\div[/tex] 170.
17.3 can be rounded to 17.0 and 18.4 to 18.0.
Therefore, equivalent to 17.3 [tex]\times[/tex] 18.4 is 17.0 [tex]\times[/tex] 18.0.
999 can be rounded to 1000 and 208 to 210.
Therefore, equivalent to 999 [tex]\div[/tex] 208 is 1000 [tex]\div[/tex] 210.
998 can be rounded to 1000 and 211 to 210.
Therefore, equivalent to 998 [tex]\times[/tex] 211 is 1000 [tex]\times[/tex] 210.

a math student is standing 40 feet from the base of a water tower. the angle of elevation from her horizontal line of sight is 72 degrees. If her "eye height" is 5 feet, how tall is the water tower? Round to the nearest foot.
9514 1404 393
Answer:
128 ft
Step-by-step explanation:
The height of the tower above eye-height is related to the angle by ...
Tan = Opposite/Adjacent
tan(72°) = (tower height above eye height)/(40 ft)
tower height above eye height = (40 ft)×tan(72°) = 123 ft
Since eye height is 5 ft, the total height of the tower from the ground is ...
tower height = eye height + height above eye height
tower height = 5 ft + 123 ft
tower height = 128 ft

Answer:
68 degrees
Step-by-step explanation:
This triangle is an isosceles triangle which means that two sides have equal lengths and when two sides have equal lengths that means that two angles are the same. so you add 56 and 56 together and you get a sum of 112. all triangles add up to a degree of 180, so you therefore subtract 112 from 180 which gives you an answer of 68 degrees , therefore x is 68
