Heavy rain in Oxford caused the Brandywine Creek to rise. The creek rose three inches the first day, and each day twice as much as the previous day. How much did the creek rise on the fifth day?
(Use Geometric Sequence Please!!!!)
Answer:
48
Step-by-step explanation:
used a calculator
The amount of the creek rise on the fifth day will be 48 inches.
What is the geometric sequences?Let a be the first term and r be the common ratio. Then the geometric sequences will be
[tex]\rm a_n = a_1} \cdot r^{(n -1 )}[/tex]
Heavy rain in Oxford caused the Brandywine Creek to rise.
The creek rose three inches the first day, and each day twice as much as the previous day.
Then we have
a₁ = 3
r = 2
Then the amount of the creek rise on the fifth day will be
n = 5, Then we have
a₅ = 3 × 2⁽⁵⁻¹⁾
a₅ = 3 × 2⁴
a₅ = 3 × 16
a₅ = 48 inches

Write an equation of a line perpendicular to line AB in slope-intercept form that passes through the point (7, 6).
y = 0.5x + 2.5
y = 0.5x − 2.5
y = −2x + 20
y = 2x − 20
The equation of a line perpendicular to line AB in slope-intercept form is
[tex]y=0.5x+2.5[/tex]
Graph :
We are given with a graph of a line ABEquation of a line perpendicular to AB passes through point (7,6)From the slope of line AB using any two points from the given line
A is (0,1) and B is (-2,5)
lets find out slope using slope formula
[tex]slope =\frac{y_2-y_1}{x_2-x_1} =\frac{5-1}{-2-0} =-2[/tex]
Slope of perpendicular lines are negative reciprocal of one another
Slope of perpendicular line is [tex]\frac{1}{2}[/tex]
Use point slope formula to find equation of the line
[tex]m=\frac{1}{2} , (7,6)[/tex]
Point slope formula
[tex]y-y_1=m(x-_1)\\y-6=\frac{1}{2} (x-7)\\y-6=0.5x-3.5\\y=0.5x-3.5+6\\y=0.5x+2.5[/tex]
The equation of a line perpendicular to line AB in slope-intercept form is
[tex]y=0.5x+2.5[/tex]

This is how i do it
(you just rearrange the number so the you can add the x's together)
15 + -5 = -2x + 3x
15 + -5 = 10
-2x + 3x = 1x or X
so you answer is:
X = 10

Which expression is equivalent to (1/y) -1/5?
Answer:
1/√y^5
Step-by-step explanation:
The value of the exponent expression [tex]\rm \left ( \frac{1}{\sqrt{y}} \right) ^{- \frac{1}{5}}[/tex] will be [tex]\rm \sqrt[10]{\rm y}[/tex]. Then the correct option is D.
What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
The exponent expression is given below.
[tex]\rm \rightarrow \left ( \dfrac{1}{\sqrt{y}} \right) ^{- \frac{1}{5}}[/tex]
Simplify the exponent expression, then we have
[tex]\rm \rightarrow \left ( \dfrac{1}{\sqrt{y}} \right) ^{- \frac{1}{5}}\\\\\rm \rightarrow \left ( \dfrac{1}{y^{1/2}} \right) ^{- \frac{1}{5}}\\\\\rm \rightarrow \left ( y^{-\frac{1}{2}} \right) ^{- \frac{1}{5}}\\\\\rm \rightarrow \left ( y \right) ^{ \frac{1}{10}}\\\\\rm \rightarrow \sqrt[10]{ \rm y}[/tex]
The value of the exponent expression [tex]\rm \left ( \frac{1}{\sqrt{y}} \right) ^{- \frac{1}{5}}[/tex] will be [tex]\rm \sqrt[10]{\rm y}[/tex]. Then the correct option is D.
