Answers
Answer:
Step-by-step explanation:
Equation for a circle of radius r, centered at (h,k):
(x-h)² + (y-k)² = r²
x² + (y+3)² = 9 is the equation for a circle of radius 3, centered at (0,-3).
Option D - Coordinate plane with no numbers marking the units. A circle is drawn on the plane, with the center at the labeled point begin ordered pair 0 comma negative 3 end ordered pair. The perimeter of the circle goes through the labeled point begin ordered pair negative 3 comma negative 3 end ordered pair IS CORRECT.
We have a equation of circle -
[tex]x^{2} +(y+3)^{2} = 9[/tex]
We have to find out which statement correctly represents the graph of this equation.
What is the general equation of circle?The general equation of the circle with radius r and center at (h, k)
is - [tex](x-h)^{2} +(y-k)^{2} =r^{2}[/tex]
The equation given to us is -
[tex]x^{2} +(y+3)^{2} = 9[/tex]
On comparing it with the general equation of the circle, we get -
[tex]x-h=x\\h=0\\\\y-k=y+3\\k=-3\\\\r^{2} =9\\r=3[/tex]
Therefore, we have a circle whose center lies at (0, -3) with radius = 3 units.
At point P(3, 3) -
[tex](-3)^{2}+(-3+3)^{2} =9\\9=9[/tex]
Hence, Option D - coordinate plane with no numbers marking the units. A circle is drawn on the plane, with the center at the labeled point begin ordered pair 0 comma negative 3 end ordered pair. The perimeter of the circle goes through the labeled point begin ordered pair negative 3 comma negative 3 end ordered pair is correct.

If the interest on a 4,600 loan is 370 what would be in the interest on a loan of 9.660
Answers
Answer:
772.17
Step-by-step explanation:
Given,
Interest (I) = 370
Principal (P) = 4600
Rate (R) = ? , Time (T) = ?
We know,
I = PTR/100
or, 370 = 4600TR/100
or, 370 = 46TR
∴ TR = 370/46 = 185/23.................(1)
Now,
On Principal (P) = 9600
Interest (I) = PTR/100
or, I = 9600TR/100
or, I = 96 * 185/23 (∵From 1)
∴ I = 772.179
Diego was trying to write 2^3 · 2^2 with a single exponent and wrote 2^3·2^2 = 2^3*2 = 2^6 . Explain to Diego what his mistake was and what the answer should be.
Answers
Answer:
2^3·2^2 = 2^3+2 = 2^5
Step-by-step explanation:
Diego was trying to write 2^3 · 2^2
He wrote 2^3·2^2 = 2^3*2 = 2^6
But this is wrong because when bases are same exponents are added.
This is the law of exponents.
The correct form would be
2^3·2^2 = 2^3+2 = 2^5

Mrs. Thomas has two rolls of garden edging that are each 96 inches long.
She wants to make two new flower beds in her back yard. Each flower bed
will be bordered by one roll of the edging. One flower bed will be in the
shape of a quadrilateral. The other will be in the shape of a triangle.
Please answer all parts. I will give brainliest for correct answer!
Answers
Answer:
A) The total length of each edging in her scale drawing would be 19.2 centimeters.
B) Square or rectangle
C) angle α= 53.13 degrees
angle β= 36.87 degrees
height= 32 inches
base= 24 inches
hypotenuse 40 inches.
Step-by-step explanation:
Part A:
If the roll edging is 96 inches long and the scale chosen is
5inches = 1 cm
96inches /5= 19.2cm
The total length of each edging in her scale drawing would be 19.2 centimeters.
Part B:
The quadrilaterals such rectangle square right trapezoid have a pair of 90 degrees angles.
If we choose a square shape then all sides must be equal. And we have a length of 19.2 centimeters.
Dividing 19.2 by 4 gives 4.8 cm for each side.
Figure A shows a square and has 4 sides equal and 4 right angles.
If we choose a rectangle shape then 2 sides must be equal. We have a length of 19.2 centimeters.
Suppose the length is 2 times more than the width
which will give the dimensions as
2*2 x+ 2x= 6x ( length and width denoted by x)
Dividing 19.2 by 6 gives 3.2 cm for each width and 6.4 for the lengths.
Figure B shows a rectangle and has 2 sides equal and 4 right angles.
It depends on which quadrilateral you wish to choose.
Part C:
Using Pythagorus theorem if the base and altitude are given then the hypotenuse can be found out using the following formula.
c²= a² +b²
c²= 6.4² +4.8²
c²= 40.96+23.04= 64
c= √64 = 8
The third side must be equal to 8 centimeters.
Using the formula
Cos α= base / hypotenuse
Cos α=4.8/8
α= Cos (inverse) 4.8/8
α= Cos (inverse) 0.6
α= 53.13 degrees
So angle α= 53.13 degrees
All the angles in the triangle must be 180 degrees.
α + β + 90°= 180°
And angle β= 180-90-53.13= 36.869= 36.87 degrees
The actual dimensions of this triangle are
height= a= 6.4* 5= 32 inches
base= b= 4.8*5= 24 inches
hypotenuse= 8*5= 40 inches.

Answer:

find angle C first
<A+<B+<C=180
90+42+<C=180
<C=180-132
<C=42°
Now use sine rule to find the value of X
a/sinA =c/sinC. where, small letters is equal to sides and capital letters is equal to angles. a=15. c=x
A=90. C=42
15/sin90°=x/sin42°

The function f is given by f(x)= (x-2) (x+4) . Without using graphing technology, answer the following questions. (graph included)
1) What are the x-intercepts of the graph representing f?
2) What are the x- and y-coordinates of the vertex of the graph?
please help!!
Answers
Answer:
x-intercepts = -4 and 2
vertex (-1, -9)
Step-by-step explanation:
To find the x-intercepts ie roots
set the equation to 0
(x - 2) (x + 4) = 0
From the zero product rule
x - 2 = 0
x = 2
x + 4 = 0
x = -4
x-intercepts = -4 and 2
--------------------------
The x coordinate of the vertex is the midpoint of the roots
x = (-4 + 2)/2
x = -1
Plug x = -1 into the function
y = (-1 - 2)(-1 + 4)
y = -3 * 3
y = -9
vertex (-1, -9)

68
Answers
Answer:
u = 24, v = 92, and w = 184
Step-by-step explanation:
According to circle theorem, we have;
∠ACD = ∠ABD = 88° by angle inscribed in a circle and also subtending the same chord
∠DOA = 2 × ∠ABD by angle subtended at the center = 2 × Angle subtended at the circumference
∴ ∠DOA = 2 × ∠ABD = 2 × 88° = 176°
w° + ∠DOA = 360 by the sum of angles at a point
∴ w° = 360° - ∠DOA = 360° - 176° = 184°
w° = 184°
w° = 2 × v° by angle subtended at the center = 2 × Angle subtended at the circumference
∴ v° = w°/2 = 184°/2 = 92°
v° = 92°
In triangle ΔCDY and ΔABY, we have;
∠ABD = ∠ABY by reflexive property
∠ACD = ∠ACY by reflexive property
∠ACD = ∠ABD = 88°
∴ ∠ABY = 88°
∠CYD = ∠AYB by vertically opposite angles are equal
∴ ∠CYD = 68° = ∠AYB
u° + ∠ABY + ∠AYB = 180° by angle sum property
∴ u° = 180° - (∠ABY + ∠AYB)
u° = 180° - (88° + 68°) = 24°
u° = 24°.

Jessica went shopping for a new watch. She found a watch that was originally priced at $50 on sale for $40. By what percent had the watch been marked down?
Answers
Answer:
20%
Step-by-step explanation:
We were given a price at $50 on sale for $40. To get the markdown percentage, take the amount of money you've discounted the merchandise at and divide it by the sales price.
$50 sweaters, you can put them on sale for $40.
[tex]50 - 40 = 10[/tex]
The difference between these two prices is $10.
Now, we need to add the amount of which it was marked down
[tex]10 + 10 = 20[/tex]
Therefore, the watch has been marked down by 20%.
