Answer:
D. The y-intercept of the graph of g is 9 units below the y-intercept of the graph of f.
Step-by-step explanation:
Subtracting 9 from the function value moves every point on the graph down 9 units. That includes the y-intercept.
D. The y-intercept of the graph of g is 9 units below the y-intercept of the graph of f.

Solve the equation for x
Ali writes the expression "half of the sum of $9$ and a number." Write an algebraic expression that is equivalent to Ali's expression. Write a second algebraic expression that is different from, but equivalent to, your first expression.
Answer:
1 ÷ 2(9 + x)
4.5 + 0.5x
Step-by-step explanation:
Given that
We write the expression i.e. half of the sum of $9 and a number
Here we need to write the two expression that is different from each other
So,
Let us assume the number be x.
Now The first equation depend on the information given will be:
= 1 ÷ 2(9 + x)
And, The second equation is
= (9 + x) ÷ 2
= 4.5 + 0.5x
Multiply and simplify. y^3 . y^5 . y^-2 .y
A. y^-4
B. 1/y^4
C. y^-5
D. 1/ y^3
Answer:
y^7
Step-by-step explanation:
y^3 . y^5 . y^-2 . y
= y^3 . y^5 . y^-2 . y^1
= y^( 3 + 5 - 2 + 1 )
= y^( 3 + 5 + 1 - 2 )
= y^( 9 - 2 )
= y^7

Which expression has a value closest to 1? (Use 3.14 as the value of .)
The Precision Scientific Instrument Company manufactures thermometers that are supposed to give readings of o°C at the freezing point of water. Tests on a large sample of these thermometers reveal that at the freezing point of water, some give readings below O°C (denoted by negative numbers) and some give readings above O C (denoted by positive numbers). Assume that the mean reading is 0°C and the standard deviation of the readings is 1.00°C. Also assume that the frequency distribution of errors closely resembles the normal distribution. A thermometer is randomly selected and tested. A quality control analyst wants to examine thermometers that give readings in the bottom 4%. Find the temperature reading that separates the bottom 4% from the others. Round to two decimal places. A. -1.48B.-1.89 C. -1.63 D. -1.75
Solution :
It is given that the Precision Scientific Instrument company Manufactures thermometers that provide readings at 0 degree Celsius for the freezing point of water.
A quality control analyst examines the thermometers which provide readings in the bottom of 4%.
Using the standard normal table, we get
P(z < z) = 4%
P(z < z) = 0.04
See the probability of 0.04 in the standard normal corresponding to the z-value is = -1.75
Therefore,
P(z < -1.75) = 0.04
z = -1.75
So the temperature reading that separates the bottom of 4% from the other thermometers is - 1.75°C
Therefore correct option is (D). -1.75

What type of triangle is ABC?
Give reasons for your answer.
Answer:
I'll say that it is a scalene triangle because all of the sides of the triangle have different lengths.
Angle CAB is congruent to angle ACD because they are alternate interior angles (note the parallel lines AB and DE). So this makes angle CAB to be 50 degrees.
For similar reasoning, angle BCE = angle ABC = 80 degrees.
Focus on the angles that are centered at point C. Those three angles form a straight line so they add to 180 degrees.
(angle ACD) + (angle ACB) + (angle BCE) = 180
(50) + (angle ACB) + (80) = 180
(angle ACB) + 130 = 180
angle ACB = 180-130
angle ACB = 50 degrees
Ultimately, this leads to triangle ABC having the interior angles of A = 50, B = 80 and C = 50.
Because we have exactly two interior angles that are the same measure, this must mean triangle ABC is isosceles. The congruent angles are opposite the congruent sides, meaning that AB = BC.
PLEASE HELP!! Find the circumference of circle K. Round your answer to the nearest hundredth. Circumference = ft
Answer:
12.57 ft
Step-by-step explanation:
Since triangle ∆EFH is a right angled triangle,side |EF| can be determined by
Sin© = Opposite side ÷ hypothenus side where © is the given angle in the triangleSin 60 = 2✓3 ÷ |EF||EF| = 2√3 ÷ sin 60|EF| = 2√3 ÷ 0.8660|EF| = 4ftSince Line |EF| is a straight line that passes through the centre of the circle and touch two sides of the circumference,
line |EF| is the diameter of the circle
Circumference = 2πr where r = radiusradius = diameter ÷ 2radius = 4 ÷ 2radius = 2 ftCircumference = 2πr Circumference = 2 × 22/7 × 2Circumference = 12.57 ftCircumference = 12.57 ftHow many solutions does the system of equations below have?
y=x+2
y=x-1
A one
B two
С none
D infinitely many
Answer:
C
Step-by-step explanation:
Answer:
C: none
Step-by-step explanation:
Here we have two separate functions named 'y.' Eliminate 'y' temporarily by equating these functions together:
x + 2 = y = x - 1
Subtracting x from both sides, we get:
0 + 2 = y = 0 - 1, or
2 = -1
This is never true, so C is the correct answer: NO solutions.
An easier way in which to do this problem is to visualize the graphs of
y = x + 2 and y = x - 1. The graphs are parallel straight lines; they never intersect, and therefore we can conclude "no solution."

In how many orders can six people line up from left to right for a group photo?
Answer:
720 possible orders
Step-by-step explanation:
To order 6 people in a line, let's imagine them as 6 possible spaces:
( )( )( )( )( )( )
Going from left to right, let's start with space 1.
There are 6 possibilities for space 1 as any of the 6 people could occupy that space in the line.
(6)( )( )( )( )( )
Next, since one person will have already occupied space 1, there are only 5 people left who can occupy space 2, so there are 5 possibilities for space 2:
(6)(5)( )( )( )( )
Continuing in this fashion, there are now only 4 people left so 4 possibilities for space 3 and etc.
(6)(5)(4)(3)(2)(1)
This means we have 6,5,4,3,2 and 1 possibilities for each space respectively.
Multiply them together and we have:
6x5x4x3x2x1 = 720 possible orders.
Hope this helped!
Answer:
We have to arrange 6 people in line
. Now, the number of ways to arrange n items = n!.
Hence, the answer is 6!=
