Estimate the square root of the following imperfect square:
7.
a. 2.2
b. 2.4
C. 2.6
d. 2.8
This problem is just try and error.
First we try number 2.5 since its the average of all the answers.
2.5^2=6.25
This is smaller than 7 so the answer is either 2.6 or 2.8
Now let's try 2.7
2.7^2=7.29
Which is bigger than 7 and that means the correct answer is 2.6 :)

1.02 quiz sinusoidal graphs
The characteristics of the sinusoidal function can be found from the given
graph of the function.
Correct Response;The minimum of the sinusoidal function is 1Method used to arrive at the above response;The sinusoidal function is the sine function that has the following general equation;
y = a·sin(b·(x - h)) + ka = The amplitude
b = Angular frequency
h = The horizontal shift
k = The vertical shift
Required:The minimum value of the sinusoidal function.
Solution;From the given graph, we have;
The amplitude, a = 2
The period, T = 10 = 2·π/b
b = π/5
The vertical shift, k = 3
The horizontal shift = 0
The minimum value of the function = k - a
Therefore;
The minimum value of the function is; 3 - 2 = 1Learn more about sinusoidal functions here:

You will need the above information to help you interpret the graph. First off, keep in mind that although this looks EXACTLY like the sine graph, if you plan on writing your equation as a function of cosine, then there WILL be a horisontal shift, meaning that a C-term will be involved. As you can see, the photograph on the right displays the trigonometric graph of [tex]\displaystyle y = 2cos\:\frac{\pi}{5}x + 3,[/tex] in which you need to replase "sine" with "cosine", then figure out the appropriate C-term that will make the graph horisontally shift and map onto the sine graph [photograph on the left], accourding to the horisontal shift formula above. Also keep in mind that the −C gives you the OPPOCITE TERMS OF WHAT THEY REALLY ARE, so you must be careful with your calculations. So, between the two photographs, we can tell that the cosine graph [photograph on the right] is shifted [tex]\displaystyle 2\frac{1}{2}\:units[/tex]to the left, which means that in order to match the sine graph [photograph on the left], we need to shift the graph FORWARD [tex]\displaystyle 2\frac{1}{2}\:units,[/tex]which means the C-term will be positive, and by perfourming your calculations, you will arrive at [tex]\displaystyle \boxed{2\frac{1}{2}} = \frac{\frac{\pi}{2}}{\frac{\pi}{5}}.[/tex]So, the cosine graph of the sine graph, accourding to the horisontal shift, is [tex]\displaystyle y = 2cos\:(\frac{\pi}{5}x - \frac{\pi}{2}) + 3.[/tex]Now, with all that being said, in this case, sinse you ONLY have a graph to wourk with, you MUST figure the period out by using wavelengths. So, looking at where the graph approximately hits [tex]\displaystyle [-10, 3],[/tex]from there to the y-intercept of [tex]\displaystyle [0, 3],[/tex]they are obviously approximately [tex]\displaystyle 10\:units[/tex]apart, telling you that the period of the graph is [tex]\displaystyle 10.[/tex]Now, the amplitude is obvious to figure out because it is the A-term, but of cource, if you want to be certain it is the amplitude, look at the graph to see how low and high each crest extends beyond the midline. The midline is the centre of your graph, also known as the vertical shift, which in this case the centre is at [tex]\displaystyle y = 3,[/tex]in which each crest is extended two units beyond the midline, hence, your amplitude. So, no matter how far the graph shifts vertically, the midline will ALWAYS follow.
**Now, the minimum value is the lowest possible value the graph touches, and in this case, the graph's lowest peaks cycle around [tex]\displaystyle y = 1,[/tex]therefore the minimum of his sinusoidal function is [tex]\displaystyle 1.[/tex]

The point (-6, 4) lies on a straight line that has a gradient of -2. What is the
equation of this line?
Given:
Point on straight line = (-6,4)
Gradient = -2
To find:
The equation of the line.
Solution:
Point-slope form: If a line passes through the point [tex](x_1,y_1)[/tex] with slope m, then the equation of the line is
[tex]y-y_1=m(x-x_1)[/tex]
The line passes through the point (-6,4) with slope -2. So, the equation of the line is:
[tex]y-4=-2(x-(-6))[/tex]
[tex]y-4=-2(x+6)[/tex]
[tex]y-4=-2x-12[/tex]
Adding 4 on both sides, we get
[tex]y-4+4=-2x-12+4[/tex]
[tex]y=-2x-8[/tex]
Therefore, the equation of the line is [tex]y=-2x-8[/tex].

A, B, C and D are points on the circumference of the circle, centre O.
DOB is a straight line and angle DAC = 58°.
Find angle CDB.
Answer:
Angle CDB = 32
Step-by-step explanation:
Here, we want to find the measure of CDB
Mathematically;
angle DCB = 90
This is because angle at the center is twice the angle at the circumference
Also;
angle CAD = angle CBD = 58
This is because they are angles in the same segment
Furthermore;
CDB + 90 + 58 = 180
This is because sum of angles in a triangle is 180
CDB = 180-90-58
CDB = 32

The cost of chartering a bus for the great america trip was split evenly by the 20 students planning to go. The day before the trip, 10 more students decided to go. dividing the cost evenly among all 30 students brought the average cost down by $9.00 per person. What was the total cost of chartering the bus? Please answer me with an explanation
Answer:
20c= 30(c-9)
Step-by-step explanation:
The first step in solving a word problem is always to organize the information you have, and put it into equations to solve.
Let c be the cost per student originally.
The cost of the bus has not changed, so the cost/student * the number of students has not changed:

Write an equation of a line that goes thru the points (-2, 6) & (3, -4)
Answer:
The equation of the line is;
y = -2x + 2
Step-by-step explanation:
Here, we want to write the equation of the line that passes through the given points
The general form of the equation is
y = mx + b
where m is the slope of the line and b is the y-intercept of the line
Mathematically, to get the slope, we use the slope formula
m = (y2-y1)/(x2-x1)
(x1,y1) = (-2,6)
(x2,y2) = (3,-4)
m = (-4-6)/(3+2) = -10/5 = -2
So the equation is in the form;
y = -2x + b
To get b, we substitute any of the two points
6 = -2(-2) + b
6 = 4 + b
b = 6-4 = 2
The equation of the line is thus;
y = -2x + 2
Ron earned $ 840 in a week . How much will he earn in 36 days
Answer:
about 4200
Step-by-step explanation:
in order to solve this, you have to understand that there are 4 weeks within a month, which would give you the answer of 3360 and 36 days is approximately 5 weeks, therefore just add one more week to the total of 3360+ 840 = 4200

Find the shaded area .
Answer:
152cm^2
Step-by-step explanation:
Find area of whole rectangle = 12 * 18 = 216cm^2
Find area of smaller square = 8 * 8 = 64cm^2
Take away the larger area from the smaller area = 216 - 64 = 152cm^2
(^2 indicates cm squared)
Hope this helps :)
Answer:
Area of the given figure is 152 sq.cm
Step-by-step explanation:
area of given figure (A)
= area of rectangle - area of minor square
=》A = (12 × 18) - (8 × 8)
=》A = 216 - 64
=》A = 152 sq.cm
If lucy has a card buiness she has an oder to make 65 cards she makes the same number of cards everyday for 7 days how many cards does she have to make on the last day
Answer:
2
Step-by-step explanation:
Total number of cards = 65
she makes the same number of cards everyday for 7 days
Number of days = 7
Cards per day = 65 / 7 = The result is 9 with a remainder of 2.
This means, she makes 9 cards per day for 7 days. Then on the last day she is left with 2 cards to make.
