se the drawing tool to form the correct answers on the provided grid. For the sequence (1, 2, 4, 8, . . .), the index starts at 1. Let f be the function that describes this sequence. Graph as much of function f as will fit on the grid.
Answer:
See attached
Step-by-step explanation:
For each increase of 1 in the index, the function value doubles. The size of the function value rapidly exceeds the limit of any linear grid.
We've shown a few points plotted. Perhaps it will give you the idea of what you need to do.
Answer:
The index starts at 1, so the domain of the function is D = {1, 2, 3, 4, 5, 6, . . .}. The sequence is based on the add 3 rule. So, to get more terms of the sequence, add 3 to the last term to get the next one. The range values include the terms of the sequence, so the range is R = {1, 4, 7, 10, 13, 16, . . .}.
To graph the function of this sequence on a coordinate plane, pair the domain values with the corresponding range values to get {(1, 1), (2, 4), (3, 7), (4, 10), (5, 13), (6, 16), . . .}. Then plot these points on the graph.

find the length of arc shown in red.
Answer:
≈10.99525 cm.
Step-by-step explanation:
1. The length of the circle is L=2πr, where π≈3.1415 and r- radius of the circle.
2. if the given arc is 45° and full circle is 360°, then the length of the arc is 45/360=0.125 of full circle, that is L(arc)=0.125L=0.25πr; ⇒ L(arc)≈0.25*3.1415*14=10.99525 (cm).
Answer:
10.99 ≈ 11cm
Step-by-step explanation:
To find the length of the arc, first we need to find the circumference of the circle, which we find with the following formula :
[tex]c=2\pi r[/tex]
where [tex]r[/tex] is the radius which is indicated in the image: [tex]r=14cm[/tex].
so the circumference is:
[tex]c=2\pi(14cm)\\c=87.96cm[/tex]
This is the measure of the entire perimeter of the circle, it is the measure of the 360 ° arc.
Because we only want 45 ° of those 360 °, we divide the value of the circumference by 360 and multiply po 45:
[tex]\frac{87.96cm(45)}{360}=\frac{3958.2}{360}=10.99cm[/tex]
which can be rounded to 11cm
The length of the arc is 11cm

What is the volume of a sphere with a diameter of 15 cm? Round the answer to the nearest whole number.
Answer:
1767 cm³
Step-by-step explanation:
We can use volume V = 4/3 π r³
We have diameter of 15 cm. To get radius, we need to divide diameter by 2.
r = 7.5 cm
So now plug in r = 7.5 then calculate V:
V = 4/3 π ( 7.5 )³
V = 4/3 π * 421.875 ≈ 1767.145 ≈ 1767

Simplify (2p+3)2 - (2p-3)2 (Give proper detailed answer with all steps,the 2 is the symbol of square)
Answer:
24p
Step-by-step explanation:
This is the difference of 2 squares:- a^2 - b^2 = (a + b)(a - b).
So here we have:-
(2p + 3)^2 - (2p - 3)^2
= (2p + 3 + (2p - 3))(2p + 3 - (2p - 3))
= (2p + 3 + 2p - 3)(2p + 3 - 2p + 3
= 4p * 6
= 24p (answer)
Final answer:
To simplify the expression (2p+3)² - (2p-3)², apply the difference of squares formula to get ((2p+3) + (2p-3)) * ((2p+3) - (2p-3)), which simplifies to 24p.
Explanation:
To simplify the expression (2p+3)² - (2p-3)², we need to apply the difference of squares formula, which is
a² - b² = (a+b)(a-b).
Here, a is (2p+3) and b is (2p-3). The result will be the product of the sum and difference of a and b.
Let's perform the simplification step-by-step:
Simplify both products:
(4p) * (6)
Finally, multiply the results to get the simplified expression:
24p
The simplified result of the expression (2p+3)² - (2p-3)² is 24p.

The answer to the long division of 533 by 41 is 13. This is reached by multiplying 13 by 41 which results in 533, the original dividend. The remainder is 0.
Explanation:Let's perform a long division of 533 by 41. First, write the number 533, which is the dividend, inside the long division bracket and the number 41, the divisor, outside of it. Now we need to see how many times 41 fits into 533.
It fits 13 times because 13 times 41 equals 533. Therefore, write 13 above on your long division bracket.
When you multiply 13 (your answer) by 41 (your divisor), you get 533, which is your dividend. Subtract 533 from 533 and you get a remainder of 0. The answer of the long division of 533 by 41 is 13.

The perimeter of the rectangular playing field is 430 yards.The length of the field is 5 yards less than triple the width. What are the dimensions of the playing field?
Answer:
Answer - 160
Step-by-step explanation:
2L+2W = 430
L = 3W-5
2(3W-5)+2W = 430
6W-10+2W = 430
8W = 440
W = 55 and L = 3(55)-5 = 160
Answer:
Length = 160 and width = 55 yards
Step-by-step explanation:
Perimeter = 2L + 2W where L = the length and W = the width.
L = 3W - 5 (given).
So substituting for L is the formula for the perimeter:-
2(3W - 5) + 2W = 430
6W - 10 + 2W = 430
8W = 440
W = 55 yards.
So the Length L = [430 - 2(55]) / 2 = 160 yards.
you have a job raking leaves. You charge 10 dollars plus .50 for each bag you fill with leaves. the equation y=0.50x+10 models this situation,where x is the number of bags and y is your total amount earned. how many bags do you fill if you earn 17 dollars
Answer:
14 bags
Step-by-step explanation:
If you earn $17, to find the number of bags substitute 17 for y in the equation y=0.50x+10. Then use inverse operations to solve for x.
17 = 0.50x+10 Subtract 10 from both sides.
17-10 = 0.50x
7=0.50x Divide both sides by 0.50
7/0.50 = x

Answer: c
y = 10.29·0.7^x . . . . . selection c seems the closest
Step-by-step explanation:For most any exponential function, the exponential multiplier will be 1 when x=0, so the y-intercept is the overall multiplier for the function.
The values decrease as x increases, so the base of the exponential term must be less than 1.
These considerations narrow your choice to C.

Step-by-step explanation:
... speed = distance/time
Fill in the given values:
... speed = (3/8 mi)/(3/5 h)
_____
Comment on units
You can use the units to provide both guidance and assurance. You know speed is generally expressed in miles per hour. If you consider "per" to mean "divided by", this expression of units tells you speed is calculated by dividing miles by hours.
If you leave the units with the numbers, as we have above, they enter into the calculation the same way any variable might. You can do the arithemetic with the numbers, and you can indicate the arithmetic with the units (just as you would with any variables). Here, the result of evaluating the equation would be ...
[tex]\displaystyle\frac{\frac{3}{8}\,\text{mi}}{\frac{3}{5}\,\text{h}}=\frac{\frac{3}{8}}{\frac{3}{5}}\,\frac{\text{mi}}{\text{h}}=\frac{5}{8}\,\text{mi/h}[/tex]
The fact that the units come out mi/h (the units of speed) provides assurance that you probably did the math correctly.

Should I round 13.9876652 to 14 or 13.99?
Answer:
14.
Unless your assignments tells you not to round to whole numbers or to round to the nearest decimal places, then 13.99. But, in most cases, you'd round to 14.
In ΔABC (m∠C = 90°), the points D and E are the points where the angle bisectors of ∠A and ∠B intersect respectively sides BC and AC . Point G ∈ AB so that DG ⊥ AB and H ∈ AB so that EH ⊥ AB .
Prove that ΔCEH and ΔCDG are isosceles.
The problem is symmetrical, so proof for ΔCDG can serve as a model for proof for ΔCEH.
Step-by-step explanation:∠DGA ≅ ∠DCA ≅ 90° . . . . given
∠GAD ≅ ∠CAD . . . . definition of angle bisector AD
AD ≅ AD . . . . reflexive property
ΔDGA ≅ ΔDCA . . . . AAS congruence theorem
CD ≅ GD . . . . CPCTC
∴ ΔCDG is isosceles . . . . definition of isosceles triangle (2 sides congruent)

To do the same for ΔCEH, replace "D" with "E", replace "G" with "H", and replace "A" with "B". The rest of the logic applies.
write a quadratic function whose graph has the given characteristics x-intercepts: -4,2 point on graph (0,-9)
y = (9/8)(x +4)(x -2)
Step-by-step explanation:When the x-intercepts are "a" and "b", you know factors of the function are (x-a) and (x-b). So, we can write the function as ...
... y = k(x -(-4))(x -2) = k(x +4)(x -2) . . . . . for some scale factor k
We can find k using the given point.
... -9 = k(0 +4)(0 -2) = -8k
Dividing by -8 gives ...
... 9/8 = k
The desired function is ...
... y = (9/8)(x +4)(x -2)
... = (9/8)(x² +2x -8)
Hari’s weekly allowance varies depending on the number of chores he does. He received $16 an alarm once a week he did 12 chores, and $14 in allowance the week he did 8 chores. Write an equation for his allowance in slope-intercept form.
Answer:
y = ($0.5/ch) x + $10
Step-by-step explanation:
Let
x = number of chores
y = allowance
The relationship between y and x can be expressed in a linear equation in the slope-intercept form.
y = mx + b
where
m is the slope
b is the y-intercept
We have the ordered pairs (8, 14) and (12, 16). We can calculate the slope using the following expression.
m = Δy/Δx = $16-$14/12ch-8ch = $0.5/ch
The equation is
y = ($0.5/ch) x + b
We will replace the first point in the previous equation.
$14 = ($0.5/ch) 8ch + b
b = $10
The final equation is
y = ($0.5/ch) x + $10
This equation can be used to predict Hari's allowance for any number of chores. For example, if Hari does 10 chores, his allowance will be $12.50. The final equation is y = ($0.5/ch) x + $10.
We are given that Hari's allowance varies depending on the number of chores he does.
We are also given two points, (8, 14) and (12, 16), that represent the relationship between the number of chores and the allowance.
We can use these two points to find the slope of the line.
The slope is equal to rise over run, which in this case is equal to
$16 - $14 / 12 - 8 = 0.5/ch.
We can now plug the slope and one of the points into the slope-intercept form of the equation to find the value of b, the y-intercept.
We will use the point (8, 14).
y = mx + b
14 = ($0.5/ch) 8ch + b
14 = $4 + b
b = $10
The final equation is y = ($0.5/ch) x + $10.
This equation can be used to predict Hari's allowance for any number of chores. For example, if Hari does 10 chores, his allowance will be $12.50.
