The correct option C which is true for the given form of the sine curve f(x) = –2sin(x) – 3.
What is the range of the function?The range of a function is defined as the set of all the possible output values that are valid for the given function.
The general form of the sine curve is given as
f(x) = –2sin(x) – 3
A.
Since this curve's A is -2, its amplitude is 2 and its range is from -2 to 2. but since the D value is -3, it shifts vertically 3 units down making the range from -1 to -5. Choice A is not true.
B.
This graph is the graph of shifted 3 units down since D is negative. This choice isn't true.
C.
Because of the (minus) sign in front of the function, the function is reflected on the x-axis, but the amplitude doesn't change. Since A value is 2, the amplitude is 2. This is true.
D.
The period depends on the B value. Here, the B value is 1, so the period is normal as the parent function of a sine curve, which is, not. So this is not correct.
Therefore, C is the correct answer.

find x and y
Answer:
x = 8, y = 6/√3.
Step-by-step explanation:
The smaller triangle and the larger triangle are similar.
4 / 4√3 = (x - 6) / y
1/√3 = (x - 6) / y
Also
y/6 = 1/√3
⇒ √3y = 6
⇒ y = 6/√3
Substitute for y in the first equation:
1/√3 = (x - 6) / 6/√3
⇒ 1/√3 * 6/√3 = x - 6
⇒ x - 6 = 2
⇒ x = 8

Please can u look at the following
Answer:
a) x = -10
b) x = 7
Step-by-step explanation:
a)
2(x+3) = x - 4
==> distribute the 2
2x + 6 = x - 4
==> add 4 to both sides
2x + 10 = x
==> subtract 2x from both sides
10 = -x
==> divide both sides by -1
x = -10
b)
4(5x - 2) = 2(9x + 3)
==> distribute the 4 and 2
20x - 8 = 18x + 6
==> add 8 to both sides
20x = 18x + 14
==> subtract 18x from both sides
2x = 14
==> divide both sides by 2
x = 7

What is the product of 9 radical 5 and 5 radical 10 in simplest radical form?
Answer:
Step-by-step explanation:
(9√5) (5√10)
The leading interger product is found by multiplying 9 and 5
The leading integer product is 9*5 = 45
The radical product is (√5*10
Factor 10
radical product = √5*2*5
There are 2 fives underneath the radical. Take one out and ignore the other
radical product = 5√2
The 5 now multiplies by 45 and √2 becomes part of the answer
5*45√2
225√2

Step-by-step explanation:
End points of [tex]\overline{RS}[/tex] are:
[tex]R (4, \:-8)\implies x_1 = 4,\: y_1=-8[/tex]
[tex]S (25, \:-1)\implies x_2 = 25,\: y_2=-1[/tex]
Point T divides [tex]\overline{RS}[/tex] in the ratio 4 : 3
[tex]\implies m = 4,\: n= 3[/tex]
Now, by section formula:
[tex]T=\bigg(\frac{mx_2+nx_1}{m+n},\:\:\frac{my_2+ny_1}{m+n}\bigg)[/tex]
Plugging in the values of [tex]x_1 ,\: y_1, \:x_2,\: y_2\:\&\: m, \: n[/tex] in the above formula, we find:
[tex]T=\bigg(\frac{4(25)+3(4)}{4+3},\:\:\frac{4(-1)+3(-8)}{4+3}\bigg)[/tex]
[tex]\implies T=\bigg(\frac{100+12}{7},\:\:\frac{-4-24}{7}\bigg)[/tex]
[tex]\implies T=\bigg(\frac{112}{7},\:\:\frac{-28}{7}\bigg)[/tex]
[tex]\implies T=(16,\:\:-4)[/tex]
Sum of the coordinates of T = 16 + (-4) = 16 - 4 = 12
Marla is making a tree skirt out of fabric. She is using a pattern based on the circle below. Marla will need to remove a sector of the circular fabric. The sector has a central angle of 60° and the radius of the circle is 3 feet.
Answer:
The area of sector is 4.71mi^2
Step-by-step explanation:
The area of the sector that Marla needs to remove is (3/2)π square feet.
How to find the surface area of some object?
Find the area that its outer surfaces possess. Sum of all those surfaces' area is the surface area of the considered object. Area is measured in terms of standard areas. Therefore, they are relative to each other.
We normally use a square of unit length as its size. That unit can be 1 cm, 1 meter, etc.
Now when we want to find surface area of some object, then the value we get tells us that you can fit this many unit sided squares on that object's surface.
We are given that;
Central angle = 60°
The radius of the circle = 3 feet.
Now,
To find the area of the sector that Marla needs to remove, we can use the formula:
A = (θ/360)πr^2
where A is the area of the sector, θ is the central angle of the sector, r is the radius of the circle, and π is pi (approximately 3.14).
Plugging in the values we know, we get:
A = (60/360)π(3)^2 A
= (1/6)π(9) A
= (3/2)π
Therefore, the area of the fabric will be (3/2)π square feet.

9) The diameter of a circular ice skating rink is 32 feet. What is the approximate area of the ice skating rink? Use a = 3.14. a) 803.84 square feet b) 50.24 square feet c) 100.48 square feet d) 64 square feet
Answer:
a) 803.84 square feet
Step-by-step explanation:
[tex]\sf{area~of~circle~=~\pi r^{2} }\\\sf{radius~ =~half~of~diameter}[/tex]
so 32 / 2 = 16 = radius
[tex]\sf{radius^{2} = 16^{2}=256}[/tex]
256 x 3.14 (because we are taking π as 3.14)
= 803.84

Adriana uses models to compare two decimal numbers. She says 0.53 is greater than 0.7 because 53 > 7.
A square partitioned into one hundred equal parts with fifty three parts shaded. To the right is a square partitioned into ten equal parts with seven parts shaded.
Which of these explains Adriana's mistake? (3 points)
a
Adriana incorrectly compared hundredths to tenths. She should compare 53 hundredths to 70 hundredths.
b
Adriana incorrectly compared tenths. She should compare 5 hundredths to 3 hundredths.
c
Adriana incorrectly shaded the models. She should shade seven more hundredths.
d
Adriana incorrectly counted the number of shaded parts in the models. She should compare 6 shaded parts to 7 shaded parts.
Answer:
A is your answer.

.7 is the same as .70 and .70 is to the left of .53, indicateing that she incorrectly compared the hundreths to the tenths.
