Answer:
The equation is ;
4x - y = 13
Step-by-step explanation:
The general equation of a straight line is;
y = mx + b
where m is the slope and b is the y-intercept
from what we are given, let us write the second equation in the general form
x + 4y = 10
4y = -x + 20
y = -1/4x + 20/4
y = -1/4x + 5
mathematically, when two lines are perpendicular, the product of their slope is -1
So for the second line with slope m2
m2 * -1/4 = -1
m2 = 4
So, using the general form, we have the equation as;
y = 4x + b
To get the value of b, we substitute the coordinates of the given point (3,-1)
-1 = 4(3) + b
-1 = 12 + b
b = -1-12
b = -13
So the equation is;
y = 4x - 13 which can be rewritten as;
4x-y = 13

Which of the following is an equation of the circle with a center at (-1,4) and a radius of 2√5 units? plss pahelp naman
A. x²+ y²+2x-8y-3=0
B. x²+y²-2x-8y+3=0
C. x²+y²+2x+8y-3=0
D. x²+y²-2x+8y+3=0
Answer:
Option A
Step-by-step explanation:
The standard form of an equation of a circle is represented by the formula [tex](x-h)^2+(y-k)^2 = r^2[/tex]. Remember that [tex](h,k)[/tex] is the center and [tex]r^2[/tex] is the radius squared.
So, the equation of the circle must be [tex](x+1)^2 +(y-4)^2 = 20[/tex]. Complete the square to change the form of the equations listed in the options and find the one that is equal.
Let's try this with option A. Move the constants to the right side, then use the completing the square method to place the equation in standard form:
[tex]x^2 + y^2 +2x -8y -3 = 0\\x^2 + y^2 +2x-8y = 3\\x^2 + 2x +y^2-8y = 3\\(x^2 +2x+1)+(y^2-8y +16)=3+1+16\\(x+1)^2 + (y-4)^2=20[/tex]
The end result matches with the equation determined before, so option A is the answer.

Answer:
Median without outlier should be 40
For the bottom questions, it should go:
Decreases the mean, does not change the median, does not change the mode
It's decreasing the mean because it goes from 44.7 to 39
Median w/ and without outlier is both 40
Mode also stays the same w/ or without the outlier, which is 96

divide 6 from both numbers
Answer:
B, 5/3
Step-by-step explanation:
hope this helps have a good day :)
-x + 2y = 6
4y - 2x = 11
-x + 2y = 6
x=− 6+2y
4y - 2x = 11
4y-2(-6+2y)=11
4y+12-4y=11
12=11

In ARST, the measure of ZT=90°, the measure of ZR=24°, and RS = 3.8 feet. Find
the length of ST to the nearest tenth of a foot.
Answer:
1.55 feet.
Step-by-step explanation:
From the question given above, the following data were obtained:
Angle R = 24°
Hypothenus = RS = 3.8 feet
Opposite = ST = x
The value of x can be obtained by using the sine ratio. This is illustrated below:
Sine R = Opposite / Hypothenus
Sine 24 = x / 3.8
Cross multiply
x = 3.8 × Sine 24
x = 3.8 × 0.4067
x = 1.55 feet
Thus, the Lenght ST is 1.55 feet.

Reflect - 25 a positive number or a negative number? Explain how you know.
Find the opposite of -25 and explain how you found your answer.
HURRY ⚠️
Answer:
-25 is negative
25 is positive
Step-by-step explanation:
-25 is negative because it's 25 spaces to the left of 0
25 is positive because it's 25 spaces to the right of 0
|-25| = 25; The opposite of -25 is 25
What is the domain of the function on the graph?
Answer:
Option 2
Step-by-step explanation:
f(x) = x + 7
and
g(x) = x2
What is g( f(-9))
Answer:
4
Step-by-step explanation:
Answer:
g(f(-9))=4
Step-by-step explanation:
This is a composite function so we need to first find the value of the function on the inside in order find the value of the composite function
f(-9)=x+7=-9+7=-2
we can put -2 instead of f(-9) in the composite function
g(-2)=(-2)^2=4

Write an explicit formula for the geometric sequence below and use it to find the 9th term. 256, 64, 16, 4, . . .
im doing this problem right now---
ok so a1=256 a2=64 a3=15 a4=4... find a9
the sequence divides by 1/4 every term
an=a1*r^n-1
an=(256)*(1/4)^n-1
replace n with 9
A9=(256)*(1/4)^9-1
A9=(256)*(1/4)^8
=(256)*(1/4)
A9=64^8
1/256 or a9= 0.00390625

Graph the line that passes through the two points. Then find the slope of the line.
Answer:
Your slope is 1
Step-by-step explanation:
This is because you go up two boxes and to the right two boxes but then you have to simplify giving you a slope of 1
The goal of the students in the club was to raise $500. They sold 43 flowerpots. By what amount did the students exceed their goal of raising $500?
Answer:
Exceeded by 145 dollars.
Step-by-step explanation:
First you multiply 15 by 43 because each pot costs 15 dollars and they sold 45.
Then you get the answer of 645 and the goal was 500 so that means you need to subtract to see how much they exceeded by.
Subtract 500 from 645 and you get the answer of 145.
So they exceeded 145 dollars.

pls help me out! how do you determine the period of the graph?
Answer:
4π
Step-by-step explanation:
Periodic graphs repeat the same pattern. Here we have a cosine function which clearly repeats itself. Start at (0, 1) and count the number of squares to the right before the graph looks the same; this occurs at (4π, 1). x has increased from 0π to 4π. Thus, the period is 4π.
A monthly salary is $1622.31. It is given an increase of 3.8%. After the first increase, it receives a second increase of 6.2%. What is the new monthly salary after both increases? Round your answer to two decimal places. Do not put the $ sign in your answer or any units. Only put the number value for your answer.
Answer:
the new monthly salary after both increase is 1,788.37
Step-by-step explanation:
The monthly salary is 1,622.31
There is an increase of 3.8%
So, the salary after first increase is
= 1,622.31 × (1 + 3.8%)
= 1,683.96
Now there is a second increase of 6.2%, so the salary after second increase is
= 1,683.96 × (1 + 6.2%)
= 1,788.37
Hence, the new monthly salary after both increase is 1,788.37

F f(x) = -2(x - 3)2 + 8
G f(x) = -2x2 + 12x - 10
H f(x) = -0.5(x - 3)2 + 2
J f(x) = -0.5x² – 3x - 6
9514 1404 393
Answer:
H f(x) = -0.5(x -3)² +2
Step-by-step explanation:
The quadratic opens downward, so the leading coefficient is negative. All answer choices agree on this.
The vertex (maximum point) is (3, 2). Choices F and H are written in vertex form. Choice F has a vertex of (3, 8); choice H has a vertex of (3, 2), so is a likely candidate.
When we look at the graph 1 unit right or left of the vertex, we see that it is about 1.5, that is, 0.5 units below the vertex. This 0.5 is the magnitude of the leading coefficient, which we already know is negative. The leading coefficient of -0.5 eliminates choices F and G.
So, choice H has the correct leading coefficient and the correct vertex.
Choice J can be eliminated by looking at the value for x=0. For J, it is -6, but we see the y-intercept of the graph is -2.5. This eliminates choice J.
The only viable choice is H.

Answer:
Q1 = 61
Q3 = 63
Step-by-step explanation:
From the plot attached :
Data obtained is :
Temperature frequency
59 0
60 2
61 3
62 3
63 4
64 2
65 1
Frequency Total 15
Data in raw format :
60,60,61,61,61,62,62,62,63,63,63,63,64,64,65
The first quartile :
Q1 = 1/4(n+1)th term
n = 15
Q1 = 1/4(15+1)th term
Q1 = 1/4 * 16th
Q1 = 4th term
Q1 = 61
Third quartile (Q3):
Q3 = 3/4(n+1)th term
n = 15
Q3 = 3/4(15+1)th term
Q3 = 3/4 * 16th
Q3 = (48/4)th term
Q3 = 12th term
Q3 = 63
Answer:
Q1 is 61 and Q3=63
