Answer: 7
Step-by-step explanation:
Step 1: Subtract 3 from both sides.
6a+3−3=45−3
6a=42
Step 2: Divide both sides by 6.
6a /6 = 42 /6
what is the equation of a circle with a radius of 7 and centered at point (3,-4)
Answer:
(x - 3)² + (y + 4)² = 49
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + *y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
Here (h, k) = (3, - 4) and r = 7 , then
(x - 3)² + (y - (- 4) )² = 7² , that is
(x - 3)² + (y + 4)² = 49 ← equation of circle

Denote the set below by set-builder notation, using x as the variable.
{1,3,5, ..., 67}
Choose the correct answer below.
O A. {x|x is even natural numbers less than 68}
B. {x|x is an odd natural number less than 68}
C. {x|x is an odd natural number between 1 and 67}
D. {x|x is an odd natural number greater than 1}
Answer:
C. {x|x is an odd natural number between 1 and 67}
Step-by-step explanation:
B and C is also correct if the natural number is defined to be started with 1: positive integer,
but if it's defined to be non-negative real number then only C
Set-builder notation of the given set is {[tex]x | x[/tex] is an odd natural number less than [tex]68[/tex]}.
What is set?
" Set is defined as the collection of the given object with certain properties."
According to the question,
Given set,
[tex]\{1,3,5, ..., 67\}[/tex]
[tex]'x'[/tex] represents the variable
A. {[tex]x | x[/tex] is an even natural numbers less than [tex]68[/tex]}.
Even numbers are multiple of 2, given set does not represents set of even numbers.
Option(A) is not the correct answer.
B. { [tex]x | x[/tex] is an odd natural number less than [tex]68[/tex]}.
[tex]\{1,3,5, ..., 67\}[/tex] represents set of odd numbers , all numbers are less than 68.
Hence, Option (B) is the correct answer.
C. {[tex]x |x[/tex] is an odd natural number between [tex]1[/tex] and [tex]67[/tex]} means [tex]\{ 3, 5, 7,...., 65\}[/tex]
Here between [tex]1[/tex] and [tex]67[/tex] excludes [tex]1[/tex] and [tex]67[/tex]. But in the given set [tex]1[/tex] and [tex]67[/tex]
are included.
Option (C) is not the correct answer.
D. {[tex]x |x[/tex] is an odd natural number greater than [tex]1[/tex]} means [tex]\{ 1, 3, 5,...........\}[/tex]
Here this set goes till infinity.
Option (D) is not the correct answer.
Hence, Option (B) is the correct answer.

NASA launches a rocket at t = 0 seconds. Its height, in meters above sea level, as a function of time is
given by h(t) = – 4.9t2 + 139t + 185,
Assuming that the rocket will splash down into the ocean, at what time does splashdown occur?
The rocket splashes down after
seconds.
How high above sea level does the rocket get at its peak?
The rocket peaks at
meters above sea level.
Answer:
the splash down occurs when h(t) = 0
0 = -4,9t2 + 139t + 185
using the quadratic formula,
t = -1.27 or 29.64 seconds
since time can't be negative
t = 29.64 secs
at the peak, h(t) is maximum
applying calculus,
[d{h(t)}}/dt = -9.8t + 139
at h(t) maximum, [d{h(t)}}/dt is 0
0 = -9.8t + 139
9.8t = 139
t = 14.18 secs
substituting,
h(t) = – 4.9t2 + 139t + 185
h(t) = -4.9(14.18^2) + 139(14.18) + 185
= 1170.77 m
Answer:
Step-by-step explanation:
y = ax² + bx + c
D = b² - 4ac
[tex]x_{12}[/tex] = ( - b ± √D ) ÷ 2a
[tex]y_{max}[/tex] = - [tex]\frac{b}{2a}[/tex]
~~~~~~~~~~~~~
h(t) = - 4.9t² + 139t + 185
- 4.9t² + 139t + 185 = 0
D = 139² + 4(- 4.9)(185) = 22947
[tex]t_{12}[/tex] = ( - 139 ± √22947) ÷ 2(- 4.9)
[tex]t_{1}[/tex] ≈ 29.641 ≈ 30 seconds
[tex]t_{2}[/tex] < 0
[tex]h_{max}[/tex] = - 4.9( [tex]-\frac{139}{2(-4.9)}[/tex] )² + 139( [tex]-\frac{139}{2(-4.9)}[/tex] ) + 185 ≈ 1170.7653 ≈ 1171 meters

What is the equation of the line shown?
the difference between 4/9 of a number and 7 is 5
first what quantities do we need to talk about?
the problem speaks of “a number”, let’s call that number x.
now write the equation that relates x to the other numbers we know.
the first clue is the word “difference”.
this means “subtraction”, but we need to subtract something from something else.
what are the two somethings? ”a number times 7” and “4”.
so, since we have a name for “a number”, let’s translate this as x*7 - 4 what else do we know?
it says the difference is 9. So complete the equation x*7 - 4 = 9 if we rewrite this cosmetically, 7x - 4 = 9
i assume that you know how to solve this for x.
so then wehn solving 7x - 4 =9 we take -4 change it to +4 so then +9 we go and get 13
7x = 13
7/7 = 13/7
x= 13/7

The table below models a exponential function. Find f(8)
Answer:
Step-by-step explanation:
f(x) = 65536(b)^x
Find b by substituting a point. (1, 16384)
16384 = 65536(b)^1
b=0.25
Thus,
f(x) = 65536(1/4)^x
Plug in 6,
f(8) = 1

If spent $2000 on new furniture. The local furniture store allows you to make a down payment of $400 and then pay the remaining balance in four equal monthly payments. Then $400 is the monthly payments
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given,
Spent $2000 on new furniture.
The local furniture store allows you to make a down payment of $400 and then pay the remaining balance in four equal monthly payments
The remaining balance can be calculated
$2000-$400=$1600
Now $1600 is to be paid in four months
Divide $1600 by 4 as we have to pay it in 4 months
1600/4
400 per month.
