The median of the following data is 10
10(2^×) + 7(3^×) = 6^× + 70
Answer:
x = 2.81 and 2.096
Step-by-step explanation:
Given the expression
10(2^x) + 7(3^x) = 6^x + 70
This can also be expressed as;
10(2^x) + 7(3^x) = (2*3)^x + 70
10(2^x) + 7(3^x) = 2^x*3^x + 70
Let a = 2^x and b = 3^x
10a + 7b = ab + 70
10a + 7b - ab = 70
10a-ab + 7b - 70 = 0
a(10-b)+7(b-10) = 0
a(10-b)-7(10-b) = 0
a-7 = 0 and 10-b = 0
a = 7 and b = 10
Since a = 2^x
7 = 2^x
log 7 = log2^x
log7 = xlog2
x = log7/log2
x = 2.81
Similarly
10 = 3^x
log 10 = log 3^x
log 10 = xlog3
x = log 10/log 3
x = 1/0.4771
x = 2.096
Hence the values of x that satisfies the equation are 2.81 and 2.096
The second hand on Mr. Vidler's Alarm Clock is 6 cm long. Approximately how far does the tip travel in 5 minutes and 15 seconds? [Round your answer to the nearest tenth. Only type in the number, no units.]
Answer:
3.28 cm
Step-by-step explanation:
The calculation is given below:
we assume the following things
R denotes the radius of the circle
And, A denotes An arc
Now , the length of the arc is
L = (A ÷ 360°) × 2 × 3.14 × R
According to the question
R = 6 cm
Angle = 5 minutes and 15 seconds
The clock could complete its revolution in 60 minutes
Therefore
60 minutes = 360°
Also
1 min = 60 seconds
So
1 seconds = 1min ÷ 60seconds
Now for 15 seconds it is
= 15 seconds × (1 ÷ 60)
= (15 ÷ 60) min
= 0.25 min
And for 5 minutes and 15 seconds, it is
= 5 min + 0.25 min
= 5.25 min
Also
60 minutes = 360°
So,
1 minute = 360° ÷ 60min
Now For 5.25min
= (5.25min) × (360° ÷ 60min)
= 31.5°
Finally the length would be
L = (31.5° ÷ 360°) × 2 × 3.14 × 6cm
= 3.28 cm

use the point-slope form to find the ewuation of the line through the points (-5,2) and (-2,6)
Answer:
The equation of the line through the points (-5, 2) and (-2, 6) is [tex]y = \frac{4}{3}\cdot x +\frac{26}{3}[/tex].
Step-by-step explanation:
The point-slope form of the equation of the line is defined by this formula:
[tex]y-y_{1} = m\cdot (x-x_{1})[/tex] (1)
Where:
[tex]x[/tex] - Independent variable.
[tex]y[/tex] - Dependent variable.
[tex]m[/tex] - Slope.
[tex]x_{1}[/tex], [tex]y_{1}[/tex] - Coordinates of the first point.
In addition, the slope of the line can be determined in terms of two distinct points:
[tex]m = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex] (2)
Where [tex]x_{2}[/tex], [tex]y_{2}[/tex] are the coordinates of the second point.
If we know that [tex]x_{1} = -5[/tex], [tex]y_{1} = 2[/tex], [tex]x_{2} = -2[/tex] and [tex]y_{2} = 6[/tex], then the equation of the line is:
[tex]m = \frac{6-2}{-2-(-5)}[/tex]
[tex]m = \frac{4}{3}[/tex]
[tex]y-2 = \frac{4}{3}\cdot (x+5)[/tex]
[tex]y = \frac{4}{3}\cdot x +\frac{26}{3}[/tex]
The equation of the line through the points (-5, 2) and (-2, 6) is [tex]y = \frac{4}{3}\cdot x +\frac{26}{3}[/tex].

2. A group of 5 friends go to a baseball game. Each person buys a ticket for the game and 2
hot dogs. Lett represent the cost of a ticket and h represent the cost of a hot dog.
a) Write two different expressions that represent the total amount this group spent. Explain
how the two expressions represent different ways of looking at the situation.
9514 1404 393
Answer:
5(t +2h)5t +10hStep-by-step explanation:
5(t +2h) --- the group total is 5 times the individual total. Each bought one ticket and 2 hot dogs.
__
5t +10h --- the group total is the total spent for tickets plus the total spent for hot dogs. 5 tickets and 10 hot dogs were purchased by the group.
Which of the following best describes the expression 6(x + 10)? (1 point)
A: The sum of a constant factor 6 and a 2-term factor x + 10
B: The product of a constant factor 6 and a 2-term factor x + 10
C: The sum of constant factors 6 and x + 10
D: The product of constant factors 6 and x + 10
Answer:
A factor can be a number, variable, term, or a longer expression. For example ... In the expression 2x+4y− 9 , the term 9 is a constant. Like Terms: Terms that contain the same variables such as 2m , 6m or 3xy and 7xy .
Step-by-step explanation:
Factor, in mathematics, a number or algebraic expression that divides another ... For example, 3 and 6 are factors of 12 because 12 ÷ 3 = 4 exactly and 12 ÷ 6 = 2 exactly. The other factors of 12 are 1, 2, 4, and 12 .

Answer:
7. Definition of midpoint
5. Definition of angle bisector
1reflexive property of equality
According to the Angle Addition Postulate, the total of two angle measurements connected by a common ray equals the size of the angle they produce.
Given, ∠PSR = ∠PST, and PS bisects the angle ∠ QSU.
Thus From the figure, ∠TSU = ∠QSR
And also given PS bisects the angle ∠ QSU. and p is the same
Thus From the figure ∠PSU = ∠PSQ
Additive property of length:
The additive property of equality in an equation asserts that the sides stay equal whether we add or subtract the same amount from both sides of the equation. For entire numbers as well, this property is valid.
Definition of angle bisector:
A "Bisector" in geometry is a line that splits a line into two distinct or equal sections. It is applied to angles and line segments.
Definition of an equilateral triangle:
An equilateral triangle in geometry is a triangle with three equal-length sides. An equilateral triangle has congruent sides, which means that each side is the same length. Additionally, each inside angle is identical (60 degrees).
Definition of midpoint:
the location on a line that is equally spaced from both ends. a time interval that lies halfway between the start and finish of an event.
Verticals angle theorem:
According to this theorem, when two straight lines cross, they create two sets of linear pairs with matching angles. The adjacent angles created by the junction of these two lines are likewise said to be supplementary, or equivalent to 180 degrees.
Therefore, Since ∠PSR = ∠PST and PS bisects the angle ∠QSU, ∠TSU = ∠QSR. Since PS divides the angle ∠QSU, ∠PSU = ∠PSQ. It is the same because PS is the same line.
