Answer:
log y = 0.576x + 0.139Step-by-step explanation:
Given data:
x | 2 | 3 | 4 | 5 | 6 y | 21 | 69 | 261 | 1029 | 4101Logarithms of y-values:
log 21 = 1.322log 69 = 1.839log 261 = 2.417log 1029 = 3.012log 4101 = 3.613The ordered pairs:
(2, 1.322), (3, 1.839), (4, 2.417), (5,3.012), (6, 3.613)Using an online calculator found the equation of the regression line:
y = 0.576x + 0.139In our case it is:
log y = 0.576x + 0.139Find the value for m
-10 + 59 = 5m = 7 + 3m

Write an equation that could be used to find the value of x using the interior angles of ∆BDC, then solve it.
9514 1404 393
Answer:
x = 16
Step-by-step explanation:
Either or both of the right triangles can be used to find x. Or, triangle ABC could be used. All numbers are assumed to be degrees.
Using ∆ABD
55 +90 +2x+3 = 180
2x = 32 . . . . . . subtract 148
x = 16
Using ∆BCD
50 +90 +2x+8 = 180
2x = 32 . . . . . . subtract 148
x = 16
Using ∆ABC
55 +(2x +3) +50 +(2x +8) = 180
4x = 64 . . . . . . . subtract 116
x = 16

Step-by-step explanation:
Answer:
6x³ - 12x² + 3x - 3
Step-by-step explanation:
f(x) - g(x)
= (6x³ - 3x² + 4x - 4) - (9x² + x - 1)
= 6x³ - 3x² + 4x - 4 - 9x² - x + 1
= 6x³ - 3x² - 9x² + 4x - x - 4 + 1
= 6x³ - 12x² + 3x - 3

The city was painting a 6 mile section of street. On the first day the painted 2 1/6 miles. On the second day they painted 1 2/3 miles. How much would they have to paint on the third day to complete the painting job?
Answer:
[tex]2\frac{1}{6}[/tex]
Step-by-step explanation:
→ Add the distances painted
[tex]2\frac{1}{6} +1\frac{2}{3} =2\frac{1}{6} +1\frac{4}{6} =3\frac{5}{6}[/tex]
→ Minus from 6 to find the third day's work

In the given diagram(see image) , TAX and TBY are tangents to the circle and C is a point on the major arc.
Question :
If <CAX = 65° , <CBY = 76° , Calculate <ATB.
Answer:
∠ATB = 102°
Step-by-step explanation:
Since ∠CBY is less than 90°, CB is not a diameter.
I did this in my head so I drew a sketch to show that around about way I did it. sketch attached:
I drew a third line from X to Y that is tangent to the circle at C.
Because each pair of tangent lines to a common point are equal, we have made three isosceles triangles.
Now we know 2 of the three angles to ΔXYT, 180 - 50 - 28 = 102° for ∠ATB
Answer:
102°Step-by-step explanation:
Given
∠CAX = 65° , ∠CBY = 76°To find
∠ATBSolution
Refer to attached picture
∠CAX= ∠CBA as same arc intercepted ∠CBY = ∠CAB as same arc interceptedTAX is a straight angle and:
∠TAB = 180° - (∠CAX + ∠CAB) = 180° - (65° + 76°) = 39°∠TBA = ∠TAB as two tangents intersect at same distance, their opposite angles are therefore same. ΔATB is an isosceles triangle.
∠ATB = 180° - 2*39° = 102°A store purchased a plasma screen TV for $770 and marked it up 150%. During a sale, the store marked it down 20%. What was the discount price on the plasma screen TV?
Answer:
1540
Step-by-step explanation:
First find the new price after the markup
The markup is
770 * 150%
770 * 1.5
1155
Add this to the original price
770 + 1155
1925
Now find the discount
1925*20%
1925*.20
385
Subtract this amount from the 1925
1925-385
1540
The final price is 1540
Answer:
Solution given:
cost price [c.p] of TV =$770
MP=c.p+ 150% of c.p=$770+150/100×770=$1925
discount [D]=20%
now
discount amount=D% of MP=20/100×1925=$385 is your answer.
$385 was the discount price on the plasma screen TV.

A string reaches from the top of a 17-foot pole to a point 13 feet from the base of the pole. To the nearest tenth of a foot, how long is the string?
Answer:
21.4 feets
Step-by-step explanation:
Using Pythagoras rule :
The length of the string:
Hypotenus = sqrt(opposite² + adjacent²)
Length of string = sqrt(17² + 13²)
Length = sqrt(289 + 169)
Length of string = sqrt(458)
Length of string = 21.400
Length = 21.4 feets

Evaluate.0.2 power of 4 =
Answer:
0.0016
Step-by-step explanation:
The expression 0.2 by the power of 4 when evaluated has a value of 0.0016
How to evaluate the expressionFrom the question, we have the following parameters that can be used in our computation:
0.2 by the power of 4
Express as an equation
So, we have
0.2 by the power of 4 = 0.2⁴
When expanded, we have
0.2 by the power of 4 = 0.2 * 0.2 * 0.2 * 0.2
Evaluate the products
This gives
0.2 by the power of 4 = 0.0016
Hence, the solution is 0.0016

Find the degree measure of the angle expressed by 11x-6.
Answer:
Won't it just be 60, because it's an equilateral triangle.
Step-by-step explanation:
60 + 60 = 120
180 - 120 = 60
11x - 6 = 60
11x = 66
x = 66/11
x = 6
Let's substitute.
11(6) - 6 = 66 - 6 = 60
