A parabola can be drawn given a focus of (3, 1) and a directrix of x = -5. What can
be said about the parabola?
The parabola has a vertex at
O,
Answer:
The statements that can be made about the parabola are;
The parabola opens towards the right
The equation of the parabola is (y - 1)² = 16 × (x + 1)
The parabola has a vertex at (-1, 1)
Step-by-step explanation:
The given focus of the parabola is (3, 1)
The directrix of the parabola, x = -5
Therefore, from the location of the directrix (on the x-axis) and the location of the focus relative to the directrix towards the positive direction of the x-axis relative to the directrix, the parabola opens towards the left of the coordinate chart
The general equation of the focus = (h + p, k)
The general equation of the directrix, x = h - p
Comparing with the values of the focus and the directrix of the given parabola, we have;
(3, 1) = (h + p, k)
-5 = h - p
Therefore, we get;
k = 1
h + p = 3...(1)
h - p = -5...(2)
Adding equation (1) to equation (2) gives;
h + h + p - p = 3 + (-5)
2·h = -2
h = -2/2 = -1
h = -1
From equation (1), we get;
h + p = -1 + p = 3
∴ p = 3 + 1 = 4
p = 4
The vertex of the parabola, (h, k) = (-1, 1)
The equation of the parabola in the form (y - k)² = 4·p·(x - h) is therefore, presented as follows;
The equation of the parabola = (y - 1)² = 4 × 4 × (x - (-1))
(y - 1)² = 16 × (x - (-1))
The equation of the parabola is (y - 1)² = 16 × (x + 1).

Find the value of angle A and angle B
hello
so these angles you can apply the "vertically opposite angles are equal" rule
angle "A" is vertically opposite to 138º so therefore angle "A" is 138º
angle "B" is verticall opposite to 42º so therefore angle "B" is 42º
hope this helped and have good day :)

Tracy's Pie Shop recently sold 15 pies, of which 3 were blackberry pies. Considering this data, how many of the next 20 pies sold should you expect to be blackberry pies?
Answer: 4
Step-by-step explanation:
We can expect that 4 of the next 20 pies sold will be blackberry pies, based on the proportion of blackberry pies in the recent sample of 15 pies.
What is Ratio?A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.
If Tracy's Pie Shop recently sold 15 pies and 3 of them were blackberry pies.
Proportion of blackberry pies = 3/15
Proportion of blackberry pies = 0.2
So, in the recent sample of 15 pies, 20% were blackberry pies.
To estimate how many of the next 20 pies sold should be blackberry pies
Let us assume that the proportion of blackberry pies in the next sample of 20 pies will be similar to the proportion in the recent sample of 15 pies.
Therefore, we can use this proportion to estimate the number of blackberry pies in the next sample of 20 pies:
Number of blackberry pies = 0.2 x 20
Number of blackberry pies = 4
Therefore, we can expect that 4 of the next 20 pies sold will be blackberry pies, based on the proportion of blackberry pies in the recent sample of 15 pies.

At a particular time of a day, a-7-m high flagstaff casts a shadow which is 8.2m long. What is the height the building which cast a shadow 20.5m in length that the same moment
Answer:
17.5m
Step-by-step explanation:
We solve using the formula
Height /Shadow
Height of flag staff = 7m
Shadow of flag staff = 8.2 m
Height of the building = x
Shadow of the building = 20.5
= 7/8.2 = x/20.5
Cross Multiply
8.2x = 7 × 20.5
x = 7 × 20.5/8.2
x = 143.5 / 8.2
x = 17.5m
The height of the building is 17.5 m

for every one rotation a small gear takes, the larger gear makes 1/6 of a rotation. If the gear makes 10 complete rotations, how many rotations will the larger gear have made
Answer:
Step-by-step explanation:
1 and 2/3 rotations. The little gear full rotation is equal to 1/6 of the big gears rotation. So if the big gear rotates once then its equal to 6 of the small rotations the extra 4 of the 10 rotations then becomes 4/6 of the big gears rotation or if simplified further, 2/3. This is my way of solving these questions

Isaac exits his house and walks 2.3 miles south. Then, he turns and walks 4.5 miles east. How far away is Isaac from his house? Round your answer to the nearest tenth and label your answer. The labelling answer is miles
Answer:
5 miles
Step-by-step explanation:
2.3 miles south
then 4.5 miles east
a^2 + b^2 = c^2
a = 2.3 miles
b = 4.5 miles
(2.3)^2 + (4.5)^2 = c^2
c^2 = 25.54
[tex]\sqrt{c^2}[/tex] = [tex]\sqrt{25.54}[/tex]
c = 5.0

if you place a 36-foot ladder against the top of a building and the bottom of the ladder is 32 feet from the bottom of the building, how tall is the building?
Answer:
16.49 feets
Step-by-step explanation:
Using Pythagoras rule, we could find, h the height of the wall ;
Using the relation :
a² = b² + c²
36² = h² + 32²
1296 = h² + 1024
h² = 1296 - 1024
h² = 272
h = √272
h = 16.49 feets

help me please
Answer:
A= -17
Step-by-step explanation:
A +-21 = -38
+21 +21
-38+21= -17
A= -17
Answer:
a = -17
Step-by-step explanation:
To solve this, we need to get A alone:
A + -21 = -38
—- +21- +21
Remember, when you do something to one side, you need to do the same thing to the other side.
Now:
A = -17!
To check:
-17 + -21 = -38
Therefore, A = -17
