Answer: (d)
Step-by-step explanation:
Given
No of tickets sold can be given by the equation
[tex]35x-260>1000[/tex]
Solving inequality
adding 260 on both sides
[tex]35x-260+260>1000+260\\35x>1260[/tex]
Now, divide the inequality by 35
[tex]x>\frac{1260}{35}\\x>36[/tex]
Thus artist need to sell a minimum of 37 tickets to earn more than $1000

Answer:
The explicit equation is [tex]\mathbf{a_n=5n+3}[/tex]
Option A is correct option.
Step-by-step explanation:
Third term of sequence is 18
Sixth term of sequence is 33
We need to find the explicit equation for the sequence.
The explicit sequence is [tex]a_n=a_1+(n-1)d[/tex]
We need to find a_1 the first term and common difference d
We have a₃=18
We can write it as: [tex]a_3=a_1+(3-1)d\\[/tex]
[tex]18=a_1+2d[/tex]
a₆=33
We can write it as: [tex]a_6=a_1+(6-1)d\\33=a_1+5d[/tex]
Now, solving these equation s we can find value of d
[tex]18=a_1+2d[/tex]
[tex]33=a_1+5d[/tex]
Subtract both equations
[tex]18=a_1+2d[/tex]
[tex]33=a_1+5d[/tex]
[tex]--------\\-15=-3d\\d=\frac{-15}{-3}\\d=5[/tex]
So, we get common difference d = 5
Now finding a_1
Put value of d in equation [tex]18=a_1+2d[/tex]
[tex]18=a_1+2(5)\\18=a_1+10\\a_1=18-10\\a_1=8[/tex]
So, we get a₁ = 12
Now, the explicit equation is:
[tex]a_n=a_1+(n-1)d\\a_n=8+(n-1)5\\a_n=8+5n-5\\a_n=5n+3[/tex]
So, the explicit equation is [tex]\mathbf{a_n=5n+3}[/tex]
Option A is correct option.
Express V in terms of T
Answer:
v = [tex]\frac{4t-1}{3}[/tex]
Step-by-step explanation:
Given
t = [tex]\frac{3v+1}{4}[/tex] ( multiply both sides by 4 to clear the fraction )
4t = 3v + 1 ( subtract 1 from both sides )
4t - 1 = 3v ( divide both sides by 3 )
[tex]\frac{4t-1}{3}[/tex] = v
The buildings of a university are mapped on a coordinate grid with the origin being at library.
The Math building is located at the point (1, 5) and the History building is located at (4, 9).
How far is it from the Math building to the History building?
Applying the distance formula, the distance between the the Math building to the History building is: 5 units.
What is the Distance Formula?To find the distance between two given points on a coordinate grid, the distance formula which is used is: [tex]d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex].
Given the following:
Math Building (1, 5) = (x1, y1)History building (4, 9) = (x2, y2).Plug in the values into the distance formula:
d = √[(4−1)² + (9 − 5)²]
d = √[(3)² + (4)²]
d = √(9 + 16)
d = √25
d = 5
Distance between the the Math building to the History building is: 5 units.

Ella traveled at an average speed of 65 per hour for 2.5 hours and then traveled at an average speed of 60 miles per hour for 3.5 hours. What was the total distance in miles traveled by Ella? *
Answer:
372.5 miles
Step-by-step explanation:
First, find how many miles she traveled at 65 mph:
65(2.5)
= 162.5
Then, find how many she traveled at 60 mph:
60(3.5)
= 210
Add these together:
162.5 + 210
= 372.5
So, Ella traveled 372.5 miles in total
What is the length segment of IL?
Answer:
IL = 11 cm
Step-by-step explanation:
Using the tangent ratio in right triangle IJL and exact value
tan45° = 1 , then
tan45° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{IL}{IJ}[/tex] = [tex]\frac{IL}{11}[/tex] = 1 , thus
IL = IJ = 11 cm
Answer:
11 cm
Step-by-step explanation:
Since m<IJL = 45 deg, and m<JIL = 90 deg, then m<ILJ is 45 deg.
That makes triangle IJL a 45-45-90 isosceles right triangle with congruent sides IJ and IL.
IL = IJ = 11 cm

The function f(X) = x^3 has been transformed, resulting in function h.
h(x) = -(x + 2)^3– 4
To create function h, function f was translated 2 units (BLANK)
translated 4 units (BLANK)
,and reflected across the
Answer:
Translated 2 units Right
and Translated 4 units left and Across the y - axis
Now the new function is
h(x) = -( x + 2 )³ - 4
Step-by-step explanation:
Step(i):-
Type of transformation change of function
a) The translated left 'c' units x - c
b) The translated Right 'c' units x + c
Step(ii)
The given function f(x) = x³
The given function is translated '2' units right side then the new function
h(x) = ( x + 2 )³
and next the translated '4 ' units left sides and reflected across the y-axis
Now the new function is
h(x) = -( x + 2 )³ - 4

Edward spends £610 on a plane ticket and $180 on airport tax. Using £1 = $1.34, what percentage of the total cost does Edward spend on airport tax? Give your answer rounded to 1 dp.
Answer: 18.0%
Step-by-step explanation:
Given: Cost of plane ticket = £610 = $ 610 x 1.34 [ £1 = $1.34 ]
= $ 817.4
Airport tax = $180
Total cost = $(817.4+180)= $997.4
The percentage of the total cost does Edward spend on airport tax = [tex]\dfrac{180}{997.4}\times100\approx18.0\%[/tex]
Hence, the required answer = 18.0%

Answer:
It is D ................
Answer:
The [tex]\mathbf{Slope=\frac{1}{4}}[/tex]
The y-intercept is (0,3)
Option D is correct.
Step-by-step explanation:
A linear function given has following points:
x y
-8 1
0 3
We need to find slope and y-intercept
To find slope, we can use formula: [tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex]
We have x_1=-8, y_1=1, x_2=0, y_2=3
Putting values and finding slope
[tex]Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{3-1}{0-(-8)}\\Slope=\frac{3-1}{0+8}\\Slope=\frac{2}{8}\\Slope=\frac{1}{4}[/tex]
So, we get [tex]\mathbf{Slope=\frac{1}{4}}[/tex]
We need to find y-intercept.
y-intercept can be found by putting x =0.
Looking at the table, when x =0, y=3
So, y-intercept is (0,3)
The required answer is:
The [tex]\mathbf{Slope=\frac{1}{4}}[/tex]
The y-intercept is (0,3)
Option D is correct.

A. -7
B. –3
C. 0
D. 4
Answer:
A) - 7
slope -intercept form y = - 3x - 7
slope m =-3 and y - intercept c = -7
Step-by-step explanation:
Explanation:-
Given that slope 'm' = -3 and point (0,-7)
The equation of the straight line passing through the point and having slope 'm'
y - y₁ = m ( x- x₁)
The equation of the straight line passing through the point ( 0,-7) and slope m = -3
y - (-7) = -3 ( x -0)
y +7 = -3x
3x +y + 7=0
The equation of the line 3x +y + 7=0
Final answer:-
slope -intercept form y = - 3x - 7
slope m =-3 and y - intercept c = -7
