Write the equation of a circle with a center of (1,-2) and radius of 4.
Answers
Answer:
(x - 1)^2 + (y + 2)^2 = 4^2
Step-by-step explanation:
The standard equation of a circle of radius r with center at (h, k) is
(x - h)^2 + (y - k)^2 = r^2
Replacing h with 1, y with -2 and r with 4, we get:
(x - 1)^2 + (y + 2)^2 = 4^2

Answers
Answer:
x = 70°, y = 110° , z = 85°
Step-by-step explanation:
∠ BEA and ∠ CDA are corresponding angles and congruent , then
x = 70°
x and y are adjacent angles and sum to 180°
x + y = 180°
70° + y = 180° ( subtract 70° from both sides )
y = 110°
∠ ABE and ∠ ACD are corresponding angles and congruent , then
z = 85°

A collection of nickels and dimes is worth 25 dollars. There are twice as many nickels as dimes. How many of each are there? Use let statements and solve algebraically.
May I please get an explanation too?
Answers
A dime is 0.1$ and a nickel is 0.05$. The total number of them should give 25$.
The number of nickels are twice the number of dimes. So lets call the number of dimes X, then the number of nickels should be 2X.
Putting it in a formula: 0.05(2X) + 0.1X = 25.
Then by solving we get:
0.1X + 0.1X = 25
0.2X = 25
X = 25/0.2 = 125
A triangle has sides with lengths of 9 feet, 14 feet, and 15 feet. Is it a right triangle?

A boy pulls the handle of a lawn mower at an angle of 30° to the horizontal with a force
of 120N. Calculate the work done when the mower moves through a distance of 12.8m.
(3mks)
Answers
If the mower is pulled over a flat horizontal surface, then first get the component of the force in the direction of the mower's displacement:
(120 N) cos(30°) = 60 √3 N ≈ 103.923 N
Then the work done by the boy on the mower over a distance of 12.8 m is
(103.923 N) (12.8 m) ≈ 1330.2 Nm ≈ 1330 J
Jade has tax deducted from her income at the rate of 24%.
Last month, after tax had been deducted, $1786 of her income remained.
Calculate her income last month before the tax was deducted.
Answers
Answer:
$2350
Step-by-step explanation:
Let Jade's total income be X
Therefore,the tax deducted was 24%x
Forming an equation:
X= 24%x + 1786
X = 0.24x + 1786
Collecting like terms
x - 0.24x = 1786
0.76x =1786
x= 1786 ÷0.76
X= $2350

Find the midpoint of the segment with the following endpoints. (10, 7) and (5, 4)
Answers
Answer:
[tex]\frac{15}{2} , \frac{11}{2}[/tex]
Step-by-step explanation:-
To find the midpoint, the equation we use is:-
[tex]\frac{x1 +x2}{2} , \frac{y1 + y2}{2}[/tex]
x1 = 10
x2 = 5
y1 = 7
y2 = 4
Substituting the values in the equation, we get:-
[tex]\frac{10+5}{2} , \frac{7+4}{2}[/tex]
Coordinates of the midpoint---> [tex]\frac{15}{2} , \frac{11}{2}[/tex]
A polr has a shadow that is 15 feet long.Mary is 4 feet tall and her shadows is 10 feet tall how tall is the pile
Answers
Answer:
The pole is 6 feet tall.
Step-by-step explanation:
The height makes the perpendicular and the shadow makes the base of the triangle in the given question
Pole Mary
Height x 4
Shadows 15 10
If the height is taken along y- axis and shadow is taken along x axis
Then
tan alpha = Perpendicular/ base
for Mary Tan alpha = 4/10
For the pole = tan alpha = x/15
Comparing x/15= 4/10
x= 4*15/10= 60/10= 6
The pole is 6 feet tall.

Find the value of two numbers if their sum is 19 and and their difference is 5
Answers
Answer:
7 and 12
Step-by-step explanation:
x - y = 5
y = (5+x)
x+ (5+x) = 19
2x +5 = 19
2x = 14
x = 7
19-7 = 12
12 +7 = 19
12-7 = 5
if a + b =19
then, a - b =5
so, a= b + 5
if, a = b + 5
then, b + b + 5= 19
(2b) + 5 =1 9
19- a(5)= 14
b= 7
a+7=19
a= 12
