Find a parametric equation for the line through the point (-8,10,0) and perpendicular to the plane 7x+5y + 5z=6 which is written using the coordinates of the given point and the
coefficients of x, y, and z in the given equation of the plane.
Let z=5t
The provided equation of the plane contains 60 as the x, y, and z coefficients.
What is the formula for a line that passes through a point and is perpendicular to a plane?The mathematical formula for the line that is parallel to the given plane and passes through the specified point. N is equal to s, which is equal to ai, bj, and ck.
The line's parametric equations are x = x0 + at, y = y0 + bt, and z = z0 + ct, which are obtained by formulating the line's vector equation in terms of its components. The direction numbers of the line are known as the components a, b, and c.
Initially, by solving for y, convert the provided line's equation into slope-intercept form. You obtain y = -2x+5, meaning that the slope is 2. We wish to find the slope of the line, which is 1/2 because perpendicular lines have opposite-reciprocal slopes.
7*-8 + 5*10 + 5*0 = 6
-56 + 50 + 0 = 6
-6 = 6
= 12.
Z = 5*12 = 60.

The population of a city was 34,000 at the beginning of 1937. Its
population steadily increased by 6.8% every year from 1937 to 1997.
Which of these is the closest to the population of the city at the end of
1970?
Answer:
298078.228074
Step-by-step explanation:
we add 6.8% of the population to the city each year
city population in year x + 1 = city population in year x + 6.8% of city population in year x = city population in year x + 0.068 * city population in year x = 1 * city population in year x + 0.068 * city population in year x = 1.068 * city population in year x
we multiply the population by 1.068 each year to get the next year's population
thus, over a period of y years, we would multiply the population by 1.068 y times.
start = 34000 in 1937
difference in years = 1970 - 1937 = 33
final amount = 34000 * 1.068 33 times = 34000 * 1.068^33 = 298078.228074

Function g is a transformation of the parent function f(x) = x^2. The graph of g is a translation right 5 units and up 1 unit of the graph of f. Write the equation for g in the form y = ax^2 + bx + c.
Answer: A transformation of a function such as y = f(x) is a way to change the appearance of its graph by applying certain rules to it. In this case, the graph of function g is a translation right 5 units and up 1 unit of the graph of f.
To find the equation of the transformed function g, we can take the equation of the parent function, which is y = f(x) = x^2 and apply the translation rules (right 5 units and up 1 unit) to it.
The translation right 5 units means that the x-coordinate of each point on the graph of f is increased by 5 units. So this can be written as x = x+5
The translation up 1 unit means that the y-coordinate of each point on the graph of f is increased by 1 units. So this can be written as y = y+1
Substituting x = x+5 and y = y+1 in the equation of the parent function y = x^2 gives the equation of g in the form:
y = (x+5)^2 + 1
So the equation of g is y = (x+5)^2 +1
This equation is a parabola with a vertex that

a rectangule has a preimeter of 446 feet. the rectangle has a length of (13x-1) feet and a width of (9x +4) feet. find the length and width of the rectangle
Answer:
Below
Step-by-step explanation:
Perimeter = 446
446 = (13x-1) + (13x-1) + (9x+4) + (9x+4) ft <====four sides added together
446 = 44x +6
440 = 44x
x = 10 then width = 9(10)+4 = 94 ft Length = (13(10)-1) = 129 ft
[tex]\frac{1}{2}[/tex]x+4=-26
[tex]\dfrac{1}{2} x+4=-26[/tex]
Subtract 4 from both sides:

Answer:
7.5 hours
Step-by-step explanation:
let t represent time, l represent length and n represent number of painters.
given t varies directly with l and inversely with n then the equation is
t = [tex]\frac{kl}{n}[/tex] ← k is the constant of variation
to find k use the condition t = 5 when l = 200 and n = 3 , then
5 = [tex]\frac{200k}{3}[/tex] ( multiply both sides by 3 )
15 = 200k ( divide both sides by 200 )
0.075 = k
t = [tex]\frac{0.075l}{n}[/tex] ← equation of variation
when l = 500 and n = 5 , then
t = [tex]\frac{0.075(500)}{5}[/tex] = [tex]\frac{37.5}{5}[/tex] = 7.5 hours
If you roll 2 dice, what is the probability that you will roll a seven (the numbers on the dice add up to a seven) on or before the 5th roll
Answer:
The probability of rolling a seven on or before the 5th roll is 5/6 or about 83.3%
Step-by-step explanation:
The probability of rolling a seven on any given roll of two dice is 1/6, since there are six ways to roll a seven (1+6, 2+5, 3+4, 4+3, 5+2, 6+1) out of the 36 possible outcomes (1-6 on the first die and 1-6 on the second die).
To find the probability of rolling a seven on or before the 5th roll, we can use the cumulative probability formula which is the probability of getting a specific event on the first roll plus the probability of getting the event on the second roll plus the probability of getting the event on the third roll and so on.
So the probability of rolling a seven on or before the 5th roll is:
P(rolling a seven on the 1st roll) + P(rolling a seven on the 2nd roll) + P(rolling a seven on the 3rd roll) + P(rolling a seven on the 4th roll) + P(rolling a seven on the 5th roll)
= (1/6) + (1/6) + (1/6) + (1/6) + (1/6)
= 5/6
So the probability of rolling a seven on or before the 5th roll is 5/6 or about 83.3%
It's worth noting that this probability is independent of the previous outcomes of the rolls, so the probability of rolling a seven on or before the 5th roll stays the same even if you already rolled a seven in previous rolls.

Find an explicit formula for the geometric sequence -3, -12, -48, -192, -768
Answer:
a4 = -3 * 4^(4-1) = -3 * 4^3 = -3*64 = -192
Step-by-step explanation:
A geometric sequence is a sequence of numbers such that the ratio of any two consecutive terms is always the same. In this case, the given sequence is -3, -12, -48, -192, -768.
To find the explicit formula for this geometric sequence, we can use the following formula:
an = a1 * r^(n-1)
where:
a1 is the first term in the sequence (-3)
an is the nth term in the sequence
r is the common ratio (the ratio between any two consecutive terms)
To find the common ratio, we can divide -12 by -3, -48 by -12, -192 by -48, and -768 by -192, and in all cases we get r = 4
Therefore, the explicit formula for this geometric sequence is:
an = -3 * 4^(n-1)
This formula can generate any term of the sequence given the value of n.
So, for example, the fourth term of the sequence, -192, can be obtained by inputting n = 4 in the explicit formula:
a4 = -3 * 4^(4-1) = -3 * 4^3 = -3*64 = -192
You deposit $320 in an account that earns simple interest at an annual rate of 7.5% IS there enough money in the account after 3 years to buy a game console that costs $400?
Answer:
no
Step-by-step explanation:
simple interest formula:
final amount = initial balance * (1 + interest rate * time)
rate = 7.5% = 0.075
initial balance = 320
time = 3
is the final amount of 320 * (1 + 0.075 * 3) greater than or equal to 400?
320 * (1 + 0.075 * 3) = 392 so no
Based on the diagram below, which is closest to the height of the tree?
answer options and picture are below
Using the concept of similar triangles, the height of the tree is; Option D: 38 ft 6 inches.
How to find the side lengths of similar triangles?Similar triangles are defined as triangles that have the same shape, but then their sizes may vary. This means that equilateral triangles and squares are good examples of similar objects. Thus, if two triangles are similar, then it means that their corresponding angles are congruent and corresponding sides are in equal proportion.
Thus, applying the principle of similar triangles above to the given image, if the height of the tree is h, then we have;
5/3.25 = h/25
h = (25 * 5)/3.25
h = 38.462 ft = 38 ft + 0.462 ft
Now, conversion of ft to inches gives 0.462 ft approximately 6 inches Thus, our final answer is 38 ft 6 inches.

What is a sector of a circle?A sector of a circle is a pie shaped part of a circle that is bounded by an arc and two radii of the circle.
The specified radius of the circle, r = 7 feet
The number of pieces to which the circle is cut into = 6 equal pieces (sectors)
The area of 2 of the pieces, using 22/7 as an approximation for π are found as follows;
Area of a circle, A = π × The square of the radius
Therefore; A = π × r²
A = (22/7) × 7² = 154
