Answer:
x= -6 twice
Step-by-step explanation:
x^2-3x-10/x^2+12x+36
By using undefined fraction we only take the denominator and equate it to 0
x^2+12x+36=0
x^2+6x+6x+36=0
(x^2+6x)+(6x+36)=0
x(x+6)+6(x+6)=0
(x+6)(x+6)=0
x+6=0 or x+6=0
x= -6 or x= -6
therefore x= -6 twice
Answer:
The first blank which is in the first row would be 9
The second blank under the 5 is 100
The third blank below the 8 is 160
And the last blank is 240
Step-by-step explanation:
It you do 60 divided by 3, it would be 20, meaning each sweater costs $20.
Since the person didn't write the answer choices they were:
A. On average, city A was warmer than city B.
B. The median and mode are different for city B.
C. The temperature range between the maximum and minimum values for city A is greater than the temperature range between the maximum and minimum values for city B.
D. The median is less for city A than for city B.
I believe it is A personally cause i took the test and got it right
Answer:
The answer to this question is 8.44 m.
Step-by-step explanation:
This problem is best illustrated in the photo below.
First, we must know that the angle stated in the problem is the angle of depression. Angle of depression is the angle between the horizontal and the line of sight of the observer. On the other hand, if the observer is looking upward, then the angle between the horizontal and his line of sight is called the angle of elevation.
Since we have the given angle of depression, we must use its complementary angle to solve for the distance of the car from the building.
Let x = complementary angle of 75°
y = distance of the car from the building
To solve for x,
To solve for y, we need to use a trigonometric function that will relate the adjacent of 15° and the opposite of 15°. Let us look at the mnemonics
SOH: Sine =
CAH: Cosine =
TOA: Tangent =
Therefore we must use the tangent function to solve for y.
So the equation is 5-x3
x^3=x*x*x
so you have x=-2
That means y=5-(-2*-2*-2)
y=5-(-8) which gives y=13
Do this for every x and get the y
