The distance from the center to where the foci is located is 8 units
How to determine the distanceThe formula associated with the focus of an ellipse is given as;
c² = a² − b²
where;
c is the distance from the focus to center a is the distance from the center to a vertex , major axis is 10 units b is the distance from the center to a co-vertex, minor axis is 6 unitsLet's use the Pythagorean theorem
Hypotenuse square = opposite square + adjacent square
Substitute the values into the formula
c² = 10² - 6²
Find the square
c² = 100 - 36
c² = 64
Find the square root
c = √64
c = 8

In rectangle ABCD, what is the length of BD¯?
Answer:
BD = √97 cm ≈ 9.849 cm
Step-by-step explanation:
Diagonal BD of rectangle ABCD is the hypotenuse of right triangle ABD. Opposite sides of the rectangle are the same length, so we have ...
AB = 4 cm
AD = 9 cm
The sides are related to the diagonals by the Pythagorean theorem.
Pythagorean theoremThe Pythagorean theorem tells you the relation between sides and hypotenuse of a right triangle:
AB² +AD² = BD²
4² +9² = BD² = 16 +81 . . . . . evaluating the squares
BD = √97 . . . . . take the square root
The length of BD is √97 cm, about 9.849 cm.
A circle is shown. The shelf is represented by a chord and the brace goes from the chord to to a point on the circle. The brace line is extended up to form a diameter.
Custom drapes are being fitted for a large circular window. It is difficult to get these measurements, but the window has an 8 ft horizontal shelf with a 2 ft brace that sits in the frame. If the brace is extended upward, it would go through the center of the shelf and the circle. What is the diameter of the window?
Diameter = feet
The length of the diameter formed is in the image given is: 10 ft.
What is a Diameter of a Circle?The diameter of a circle is the line segment that divides the circle into two equal halves. The diameter divides the circle into semicircles. Also, the diameter of a circle is twice the length of the radius of a circle.
If we know the length of the radius, we can determine the length of the diameter of a circle by multiplying the radius by two. On the other hand, if we know the length of the diameter, to find the length of the radius, divide the diameter by 2.
The image of the circle showing the shelf and the brace line, which is the diameter are shown below.
To find the diameter of the window, add the length of the horizontal shelf and length of the brace. Thus:
Length of the diameter of the window = 8 + 2
Length of the diameter of the window = 10 ft
Thus, the length of the diameter formed is: 10 ft.

BC is tangent to circle A at point B.
Find m/CAB if m/ACB=62".
Enter your answer in the box.
m/CAB
Answer:
28
Step-by-step explanation:
Tangent is a line that touches the circle at one point and is perpendicular to the radius. Circle A has radius AB and tangent CB, so AB is perpendicular to CB. Therefore triangle ABC is a right angle, with angle B measuring 90 degrees. Since interior angles of a triangle add up to 180 degrees, measure of angle A is 180 - 90 - 62 = 28 degrees.
Q2. A train travels at a constant speed of 45 m/s. a) Calculate the distance travelled by the train in:
i) 30 s
ii) 2 minutes.
the train travels at 45 meters per each second
this question can be rewritten into the equation d = 45t, where d represents the distance traveled and t represents the time elapsed.
we are given two seperate times, so we can replace the variable t with each respective time. this leaves us with only one missing variable, so we can successfully isolate to find the other.
for i), we substitute t for 30 seconds, shown as follows
d = 45t
d = 45(30)
d = 1350m
for ii), we know that there are 60 seconds in every minute, so in multiplying 60 seconds by two we get the total amount of seconds in two minutes, which is 120.
we can now use 120 to substitute t in our equation
d = 45t
d = 45(120)
d = 5400m
hope this helps!!
Answer:
i) 1350 m
ii) 5400 m
Step-by-step explanation:
To calculate the distance traveled by the train, we can use the formula:
[tex]\large\boxed{\sf Distance=Speed \times Time}[/tex]
[tex]\hrulefill[/tex]
Question (i)Given values:
Speed = 45 m/s (meters per second)Time = 30 secondsSubstitute the given values into the formula for distance:
[tex]\begin{aligned}\sf Distance&= \sf 45\; m/s \times 30\;s\\& = \sf 1350\:m\end{aligned}[/tex]
Therefore, the train travelled a distance of 1350 meters in 30 seconds.
[tex]\hrulefill[/tex]
Question (ii)Given values:
Speed = 45 m/s (meters per second)Time = 2 minutesAs the time is given in a different unit of time than the speed, we must first convert the time into seconds. As 1 minute = 60 seconds, then:
[tex]\sf 2\; minutes = 60 \;s \times 2 = 120 \;s[/tex]
Substitute the given values into the formula for distance:
[tex]\begin{aligned}\sf Distance&= \sf 45\; m/s \times 120\;s\\& = \sf 5400\:m\end{aligned}[/tex]
Therefore, the train travelled a distance of 5400 meters in 2 minutes.

Where r is the radius of the circumference.
So in our case:
c = [tex]2 \cdot \pi \cdot 4yd = 8\cdot \pi[/tex] yd.
The circumference of the circle, in the attached image is approximately 25.1 yards.
How to calculate the circumference of the circleTo find the circumference of a circle, you can use the formula:
Circumference = 2 * π * radius
where π = 3.14159.
Given the radius of the circle is 4 yards, the circumference can be calculated as follows:

Find the value of t such that f(t) = 128.
Answer:
t = 7
Step-by-step explanation:
You can use your knowledge of powers of 2, or you can use logarithms to find the value of t.
Powers of 22^1 = 2
2^2 = 4
2^4 = 16
128 = 16×4×2 = (2^4)(2^2)(2^1) = 2^(4+2+1) = 2^7
Now, the equation is ...
f(t) = 2^t = 2^7
Equating exponents, we have ...
t = 7
LogarithmsTaking the log of both sides of the equation ...

Using the midpoint formula, the coordinates of the other endpoint, V is: B. (10, -25.8).
What is the Midpoint Formula?To find the coordinates of the midpoint of a segment, the midpoint formula is used, which is expressed as: M(x2 + x1/2, y2 + y1/2).
Given one endpoint of UV as, U(21.6, -8.2), and a midpoint of M(15.8, -17), let:
U(21.6, -8.2) = (x1, y1)
V(x, y) = (x2, y2)
Plug in the values into M(x2 + x1/2, y2 + y1/2):
M(15.8, -17) = (x2 + 21.6/2, y2 + (-8.2)/2)
Solve for x2
15.8 = (x2 + 21.6)/2
Multiply both sides by 2
2(15.8)= (x2 + 21.6)/2 × 2
31.6 = x2 + 21.6
Subtract both sides by 21.6
31.6 - 21.6 = x2 + 21.6 - 21.6
10 = x2
x2 = 10
Solve for y2:
-17 = (y2 + (-8.2))/2
Multiply both sides by 2
2(-17) = (y2 + (-8.2))/2 × 2
-34 = y2 + (-8.2)
-34 = y2 - 8.2
Add 8.2 to both sides
-34 + 8.2 = y2 - 8.2 + 8.2
-25.8 = y2

If joseph sells his home, profit will he make = (a) $79720
What is profit and its example?
Profit is a term that often describes the financial gain a business receives when revenue surpasses costs and expenses. For example, a child at a lemonade stand spends one quarter to create one cup of lemonade. She then sells the drink for $2. Her profit on the cup of lemonade amounts to $1.75.Profit earned on the house if he sells = $79720
Amount paid by Joseph for his home = $105000
His house has increased its property value by 2.0% every year
So, Property cost after 20 years :
[tex]Cost = 105000 * (1.02)^{20}[/tex]
Cost = 105000 × 1.4859
Cost = 156020
Also, Due to renovations and improvements to the house, the property cost is increased by $28700
So, Total cost of the house after 20 years = 156020 + 28700
= $184720
So, Profit earned on the house if he sells = 184720 - 105000
