Find the value of x.
Answer:
x = -7
Step-by-step explanation:
All triangle angles add up to 180
84 + x + 59 + x + 51 = 180
2x + 194 = 180
2x = 180 - 194
2x = -14
x = -7

The diagonals of a quadrilateral are 12 and 10. Is
this a parallelogram rectangle? Explain your answer
Answer:
the answer is no.a parallelogram is not a rectangular but the opposite is true. the reason is a cause of parallelogram's diagonals.they might not be equal in parallelogram but in rectangular they must be equal.
Step-by-step explanation:
Answer:
If both pairs of opposite sides of a quadrilateral are congruent, then the quadrilateral is a parallelogram. So yes it is a parallelogram.
Step-by-step explanation:
Diagonals of parallelogram are not necessarily equal. This is a known property of a parallelogram. If all angles are equal, then it means its opposite angles are also equal which is a condition for a quadrilateral to be called parallelogram. If all sides are equal then, opposite sides are also equal.
what is the input of arccos
Answer:
It returns the angle whose cosine is a given number.
Step-by-step explanation:
For every trigonometry function, there is an inverse function that works in reverse. These inverse functions have the same name but with 'arc' in front. (On some calculators the arccos button may be labeled arccos, or sometimes cos-1.) So the inverse of cos is arccos etc. When we see "arccos x", we understand it as "the angle whose cosine is x"
cos30 = 0.866 Means: The cosine of 30 degrees is 0.866
arccos 0.866 = 30 Means: The angle whose cosine is 0.866 is 30 degrees.
Use arccos when you know the cosine of an angle and want to know the actual angle.
Which is the correct answer?
Answer:
The first one
Step-by-step explanation:
Find the value of x.
Answer:
x = 30°
Step-by-step explanation:
< A = 90° {Being vertically opposite angles }
Now
x + 90° + 2x = 180° (Being linear pair)
3x = 180° - 90°
3x = 90°
x = 90° / 3
x = 30°

Buying one movie ticket online costs $16.50. Two tickets cost $30.50. Assuming that the relationship is linear, what is the recursive formula? (remember recursive formula is An = An-1 + d)
1. An = A1 + (n - 1) +30.50
2. An = An-1 + 14 where A1 = 16.50
3. A20 = 231
4. An = 30.5 + 16.50
Answer:
c(n)= 14n+2.50

Dalton built a linear model to show the height of a meteor falling to the Earth. The meteor starts at 100 km above the Earth's surface and falls at a rate of 20km per second. The x values represent the time in seconds and the y values represent the height of the meteor. What does the domain represent in context of the model?
Answer:
The domain represents the time of motion of the meteor as it falls from 100 km height above the Earth's surface at a speed of 20 km
Step-by-step explanation:
The given parameters from the question are;
The elevation of the meteor above the Earth's surface = 100 km
The rate at which the meteor falls = 20 km per second
The 'x' values represent the time in seconds and the 'y' values represent the meteor's height
Therefore, we have;
y = 100 - 20·x
The domain of a function is the set of inputs to the function
Therefore, the domain represent the time it takes the meteor to reach the given 100 km height above the Earth's surface
At the start x = 0 seconds
On the Earth's surface, y = 0, therefore;
0 = 100 - 20·x
x = 100/20 = 5
When the meteor just touches the Earth's surface x = 5 seconds
Therefore, the domain is 0 ≤ x ≤ 5.

$5.10 in sales tax, what was the sales tax rate?
Answer:
We can convert 6.75% to a decimal by dividing by 100.
If x is the price of the house, then the sales tax is 0.0675x. The price of the house and the sales tax add up to $319,000.
x+0.0675x=319,000
Combe terms on the left.
1.0675x=319,000
Finally, divide both sides by 1.0675.
x=319,0001.0675=298,829.04

People (p)
F. c = 16p

G. C = 75p + 13

Total Charge (c)
$400
$725
$1,050
$1,375
75
H. p = 13c + 75
100
J. c = 13p + 75
Answer:
The answer is j
Step-by-step explanation:
The equations shows the relationship between c and p is p= 13c + 75.
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
We have table which shows amount that a catering company charges based on the number of people at an event.
So, the equation that can framed from the table as
(y- 400)= (725- 400) / (50-25) . (x-25)
y- 400 = (325/ 25) (x-25)
y-400 = 13(x-25)
y-400 = 13x - 325
y = 13x - 325 + 400
y= 13x + 75
or p = 13c+ 75
