Answer:
y = -9x +5Step-by-step explanation:
Slope = -9
y-intercept = 5
In [tex]y = mx +b[/tex] ;
m = slope
b = y-intercept
So just replace -9 for m and 5 for b in slope intercept form;
[tex]y = -9x +5[/tex]

find the measure of angle E
Answer:
E = 76°
Step-by-step explanation:
Exterior angle B = 116°
So ABC = 180° - 116°
= 64°
In triangle ABC , AC = BC ( given )
So angle BAC = angle ABC = 64° ( Opposite angle of two same sides of a triangle are equal )
According to Angle Sum Property of a Triangle ,
BAC + ABC + ACB = 180°
=> ACB + 64° + 64° = 180°
=> ACB = 180° - 128°
= 52°
Also , angle ACB = angle ECD = 52° ( Vertical Opposite Angles are equal )
In triangle ECD ,
EC = ED ( given )
So, angle ECD = angle EDC = 52° ( Opposite angle of two same sides of a triangle are equal )
According to Angle Sum Property of a Triangle ,
ECD + EDC + CED = 180°
=> 52° + 52° + CED = 180°
=> CED = 180° - 104°
= 76°

Evaluate 5^-4. Write your answer as a fraction in simplest form
Answer:
exact form = 1/625
decimal form = 0.0016
The expression written as a fraction in simplest form is [tex]\frac{1}{625}[/tex]
From the question,
We are to evaluate 5^-4.
First, we will write the expression properly.
The given expression is 5⁻⁴
Now, we will write the expression as a fraction
From one of the laws of indices, we have that
[tex]a^{-x} =\frac{1}{a^{x} }[/tex]

A florist has 49 red roses and 63 white roses. The florist wants to put an equal number of red roses in each centerpiece, along with an equal number of white roses in each, using all the flowers. What is the greatest number of centerpieces the florist can make, and how many of each flower will they have?
Number of red roses a florist has = 49
Number of white roses a florist has = 63
To find the number of centerpieces with equal number of white and red roses we will find the greatest common factor of both the numbers,
49 = [tex]7\times 7[/tex]
63 = [tex]7\times 9[/tex]
GCF of 49 and 63 = 7
Therefore, number of centerpieces = 7
Now divide the total number of red roses by GCF to find the number of red flowers in each centerpiece.
Number of red roses in each centerpiece = 7
Similarly, number of white roses in each centerpiece = 9

Determine whether the geometric series 19.2 + 9.6 + 4.8 + ... converges or diverges, and identify the sum if it exists.
Answer: The infinite geometric series converges to 38.4
====================================================
Explanation:
Divide each term by its previous term
term2/term1 = 9.6/19.2 = 0.5
term3/term2 = 4.8/9.6 = 0.5
The common ratio is r = 0.5
Since -1 < r < 1 is true, this means the infinite geometric series converges.
It converges to...
S = a/(1-r)
S = 19.2/(1-0.5)
S = 38.4
Answer:
Top is right
Step-by-step explanation:
An environmental study of a certain community suggests that t years from now, the average level of carbon monoxide in the air will be Q(t)=0.05t^2 + 0.1t + 3.4 parts per million. By approximately how much will the carbon monoxide lvel change during the coming 6 months?
Answer:
3.4625
Step-by-step explanation:
Given the equation:
Q(t)=0.05t^2 + 0.1t + 3.4 parts per million
Where t = time in years
By approximately how much will the carbon monoxide lvel change during the coming 6 months?
t = 6 months = 6/12 = 0.5 year
Q(0.5) = 0.05(0.5)^2 + 0.1(0.5) + 3.4 parts per million
Q(0.5) = 0.05(0.25) + 0.05 + 3.4
Q(0.5) = 0.0125 + 0.05 + 3.4
Q = 3.4625
Carbon monoxide level will change by approximately 3.4625 parts per million in 6 months

Tutoring Services: Suppose that 40% of community college students never use tutoring services available at their college. Suppose we randomly select samples of community college students. For each sample we calculate the proportion who do not use tutoring. If we randomly sample 500 students at a time, what will be the mean and standard error of the sampling distribution of sample proportions
Answer: The mean and standard error of the sampling distribution of sample proportions are 0.40 and 0.0219 respectively.
Step-by-step explanation:
Formula : Mean of the sampling distribution of sample proportions
[tex]\mu_p= p[/tex]
Standard error of the sampling distribution of sample proportions
[tex]\sigma_p=\sqrt{\dfrac{p(1-p)}{n}}[/tex]
, where p = population proportion
n= sample size
Here, p =0040
n= 500
So , Mean of the sampling distribution of sample proportions
[tex]\mu_p= 0.40[/tex]
Standard error of the sampling distribution of sample proportions
[tex]\sigma_p=\sqrt{\dfrac{0.40(1-0.40)}{500}}\\\\=\sqrt{\sdfrac{0.40\times0.60}{500}}\\\\=\sqrt{\dfrac{0.24}{500}}\\\\=\sqrt{0.00048}\\\\\approx0.0219[/tex]
Hence, mean and standard error of the sampling distribution of sample proportions are 0.40 and 0.0219 respectively.

Area of triangle = 1/2 × b × h
b = base and h = height
Area = 1/2 × (x+4) × (2)
Area = x + 4Area of rectangle = lb
l = Length and b = Breadth
Area = 10 (x + 2)
Area = 10x + 20
Given:The area of rectangle is 8 times greater than the area of the triangle.
Solution:According to the question,
10x + 20 = 8(x+4)
or, 10x + 20 = 8x + 32
or, 10x - 8x = 32 - 20
or, 2x = 12
or, x = 12/2 = 6
Answer:The value of x is 6.
Hence, Option D. 6 is correct.
Answer:
x = 6
Step-by-step explanation:
Area of rectangle = length * width
= 10 *(x +2)
= 10*x + 10*2
= 10x + 20 unit²
Area of triangle = [tex]\frac{1}{2}bh[/tex]
[tex]=\frac{1}{2}*2*(x +4)\\\\=1*(x+4)\\\\= x +4[/tex]
Area of rectangle = 8*area of triangle
10x + 20 = 8* (x+ 4)
10x + 20 = 8x + 32 {Subrtact 20 from both sides}
10x = 8x + 32 - 20
10x = 8x + 12 {subtract 8x form both sides}
10x - 8x = 12
2x = 12 {divide both sides by 2}
2x/2 = 12/2
x = 6

given the slope of the line and one point that it passes through represent the equation of the line in point slope form then rewrite the equation in slope intercept form.
part A: (-4,7);m=-3/4
Slope intercept form needs two things. The slope and y-intercept.
y = mx + b
m = the slope
b = y-intercept.
In this problem, we are given the slope and a point the line passes through.
m = -3/4
So far we have y = -3/4x + b
To find b, we need to plug the point into the line.
-4 is the x-coordinate, so we plug -4 into x
7 is the y-coordinate, so we plug 7 into y
7 = -3/4(-4) + b
Simplify.
7 = 3 + b
Subtract 3 from both sides.
4 = b
Our equation is: y = -3/4x + 4
The point-slope intercept of the given line with slope -3/4 and passes through (-4,7) is y = (-3/4) x + 4.
What is a linear function?A straight line on the coordinate plane is represented by a linear function.
A linear function always has the same and constant slope.
The formula for a linear function is f(x) = ax + b, where a and b are real values.
As per the given,
(-4,7);m=-3/4
The equation of a linear line in point-slope point is given as,
y = mx + c
Put (-4,7);m=-3/4
7 = -3/4 (-4) + c
c = 7 - 3 = 4
Thus equation will be as, y = (-3/4) x + 4
Hence "The point-slope intercept of the given line with slope -3/4 and passes through (-4,7) is y = (-3/4) x + 4".
