find the 10th term f(1) = 30 ; f(n) = 2 * f(n-1) -50
Answer: :F(x)=x^2+x-6
The 10th term of the given sequence is -10190.
What is the function?Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.
The given function is f(1)=30; f(n)=2×f(n-1)-50.
Here,
When n=2
f(2)=2×f(2-1)-50
=2×f(1)-50
= 2×30-50
= 10
When n=3
f(3)=2×f(3-1)-50
=2×f(2)-50
= 2×10-50
= -30
When n=4
f(4)=2×f(4-1)-50
=2×f(3)-50
= 2×(-30)-50
= -60-50
= -110
When n=5
f(4)=2×f(5-1)-50
=2×f(4)-50
= 2×(-110)-50
= -220-50
= -270
When n=6
f(4)=2×f(6-1)-50
=2×f(5)-50
= 2×(-270)-50
= -540-50
= -590
When n=7
f(4)=2×f(7-1)-50
=2×f(6)-50
= 2×(-590)-50
= -1180-50
= -1230
When n=8
f(4)=2×f(8-1)-50
=2×f(7)-50
= 2×(-1230)-50
= -2510
When n=9
f(4)=2×f(9-1)-50
=2×f(8)-50
= 2×(-2510)-50
= -5070
When n=10
f(4)=2×f(10-1)-50
=2×f(9)-50
= 2×(-5070)-50
= -10190
Therefore, the 10th term of the given sequence is -10190.

If you mix red and white paint in different ratios, you will get different shades of pink paint. If the ratios are equivalent, the shades of pink will be the same. ◦ Mai mixed a batch of pink paint using 5 cups of red paint and 3 cups of white paint. ◦ Priya mixed another batch of pink paint using 7 cups of red paint and 4 cups of white paint. Are these two batches the same shade of pink? Explain.
Answer:
No,
Step-by-step explanation:
be a light pink and one would be a darker shade of pink.because
The given two batches doesn't have the same shade of pink because the proportion of 7 cups of red : 4 cups of white is greater than 5 cups of red : 3 cups of white.
What is proportion?A proportion is an equation in which two ratios are set equal to each other. In simple words, equivalent fraction are called as proportions.
Now it is given that,
Mai's pink contains- 5 cups of red paint and 3 cups of white paint
So, Ratio of red : white = 5 : 3
⇒ 5/3 = 1.67
Priya;s pink contains- 7 cups of red paint and 4 cups of white paint
So, Ratio of red : white = 7 : 4
⇒ 7/4 = 1.75
Thus, the proportion of 7 : 4 > 5 : 3
Thus, the given two batches doesn't have the same shade of pink because the proportion of 7 cups of red : 4 cups of white is greater than 5 cups of red : 3 cups of white.

Please help with this simultaneous equation you can use any method(Only number 6)
Answer:
Pencil: $0.60 Rubber: $0.48
Step-by-step explanation:
Let the cost of a pencil be p and the cost of a rubber be r.
[tex]p+r=1.08[/tex] (Equation 1)
[tex]4p=5r[/tex] (Equation 2)
Divide both sides by 4:
[tex]p=\frac{5}{4} r[/tex]
Substitute this into Equation 1:
[tex]\frac{5}{4} r+r=1.08[/tex]
Multiply both sides by 4:
[tex]\frac{5}{4}r* \:4+r* \:4=1.08*4[/tex]
[tex]5r+4r=4.32[/tex]
[tex]9r=4.32[/tex]
Divide both sides by 9:
[tex]\frac{9r}{9}=\frac{4.32}{9}[/tex]
[tex]r=0.48[/tex]
Since r + p = 1.08,
[tex]p=1.08=0.48=0.60[/tex]
What is the value of x in 6 - 4x = 7x - 9x + 10
Answer:
[tex]x=-2[/tex]
Step-by-step explanation:
So we have the equation:
[tex]6-4x=7x-9x+10[/tex]
First, combine like terms on the right:
[tex]6-4x=-2x+10[/tex]
Add 4x to both sides. The left cancels:
[tex]6=2x+10[/tex]
Subtract 10 from both sides. The right cancels:
[tex]-4=2x[/tex]
Divide both sides by 2:
[tex]x=-2[/tex]
So, the value of x is -2.
And we're done!
Step-by-step explanation:
[tex]6 - 4x = 7x - 9x + 10 \\ 6 - 4x = - 2x + 10 \\ 6 - 10 = - 2x + 4x \\ - 4 = 2x \\ x = \frac{ - 4}{2} \\ x = - 2[/tex]

write an equation in slope-intercept form for the line passing through each pair of points. (-4,-2) and (2,3)
Answer:
y = 5/6x +4/3
Step-by-step explanation:
The 2-point form of the equation for a line is a useful place to start.
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
y = (3 -(-2))/(2 -(-4))(x -(-4)) -2
y = 5/6(x +4) -2
y = 5/6x +20/6 -12/6
y = 5/6x +4/3

The length of a rectangle is 4 units shorter that half the with .if the length of the rectangle is 18 units,which equation can be used to find w , the width of rectangle
Hey there! I'm happy to help!
Let's call our length and width L and W respectively.
L=1/2W-4
L=18
Since L is equal to 18, we can just replace the L in the first equation with 18 and solve.
1/2W-4=18.
We add 4 to both sides.
1/2W=22
We divide both sides by 1/2.
W=44

Write a function g whose graph represents a reflection in the y-axis followed by a translation 3 units to the right of the graph of f(x)=|x|.
g(x)=
Answer:
[tex]g(x) = |x - 3|[/tex]
Step-by-step explanation:
Given
[tex]f(x) = |x|[/tex]
Required
Translate 3 units right
The result of a right translated function is:
[tex]g(x) = f(x - h)[/tex]
Where h is the unit of translation
[tex]h = 3[/tex]
[tex]g(x) = f(x - 3)[/tex]
Solve for f(x - 3)
[tex]f(x) = |x|[/tex]
[tex]f(x - 3) = |x - 3|[/tex]
Hence;
[tex]g(x) = |x - 3|[/tex]
