The function whose graph is given by: y = sin x-3 because sin starts at 0 and goes up. Therefore, the correct option is D.
What is a function?Function is a type of relation, or rule, that maps one input to specific single output.
A graph contains data of which input maps to which output.
Analysis of this leads to the relations which were used to make it.
For the example, if the graph of a function is rising upwards after a certain value of x, then the function must be having increasingly output for inputs greater than that value of x.
If we know that function crosses x axis at some point, then for some polynomial functions, we have those as roots of the polynomial.
The function whose graph is given by: y = sin x-3 because sin starts at 0 and goes up.
Therefore, the correct option is D.

Step-by-step explanation:
If the vertex H of a triangle is at (- 2, 2) , what are the coordinates of H in the dilation of the triangle when the origin is the center of dilation and the scale factor is 3?
Answer:
The coordinates of H after the dilation is (-6,6)
Step-by-step explanation:
Here, we want to get the coordinates of the image given the coordinates of the pre-image
with the dilation factor and the coordinates, what we have to do is to simply multiply each of the coordinates of the point on the vertex by 3
Mathematically, we have this as;
H’ = 3H
so;
(-2,2) becomes; (3 * -2, 3 * 2) = (-6,6)

Paul went to a solar panel store and paid $923.40 per solar panel for two solar panels and a flat rate fee for installation for a total of $1944.80. Brad went to another solar panel store and paid $940.50 per solar panel for two solar panels plus a per solar panel installation fee for a total of $1983.60. What is the difference in the amounts they paid in installation charges? A. $5.60 B. $4.60 C. $3.60 D. $6.60
Answer:
b) $4.60
Step-by-step explanation:
a)
2 panels at $923.40 each = $1846.80
Total with installation: $1944.80
Installation $1944.80-$1846.80 = $98
b)
2 panels at $940.50 each = $1881.00
Total with installation: $1983.60
Installation $1983.60-$1881.00 = $102.60
Substract a from b
102.60-98 = 4.60

In a recent year, 23.9% of all registered doctors were female. If there were 47,400 female registered doctors that year, what was the total number of registered doctors?
Round your answer to the nearest whole number.
Answer:
23.9% = 47400
divide both sides by 23.9 to find 1%
1% = 1983.26359
now multiply by 100 to find total number of doctors
1983.26359 X 100
100% = 198326

Find the perimeter and area of the polygon shown below.
O P = 76 feet, A = 338 square feet
OP= 58 feet, A = 338 square feet
OP = 91 feet, A = 390 square feet
O P = 76 feet, A = 330 square feet
p = 76 a = 330 so your answer is D
The perimeter of the polygon is 76ft and Area is 338 sq.ft, the correct option is A.
What is a Polygon?A polygon is a closed structure with 3 or more than 3 sides.
The given polygon has 4 sides, so it is a quadrilateral
To find the area of the polygon, it can be divided into a rectangle and a triangle as shown
Area of Rectangle = Length * Width
Area of Triangle = (1/2) * base * height
Area of Rectangle = 15 *18
Area of Rectangle = 270 sq.ft
Area of Triangle = (1/2) * 8 *17
Area of Triangle = 4 * 17
Area of Triangle = 68 sq.ft
Therefore, the total area = 68 +270 = 338 sq.ft.
Perimeter of a polygon is equal to sum of all the sides
= ( 15+18+17+18+8)
= 76 ft.

A campsite in the shape of a rectangle FGHI has sides (3x + 6) m and (x+1) m and the length of the diagonal FH is (4x+1) m. Find the area of the campsite
Answer:
168 m²
Step-by-step explanation:
A rectangle is a quadrilateral (four sides) with two pairs of equal opposite sides. All the four angles in a rectangle are equal to 90°.
Given the sides of rectangle FGHI as (3x + 6) m and (x+1) m and the diagonal as (4x + 1) m.
Hence, from Pythagoras theorem:
(4x + 1)² = (3x + 6)² + (x + 1)²
16x² + 8x + 1 = (9x² + 36x + 36) + (x² + 2x + 1)
16x² + 8x + 1 = 10x² + 38x + 37
16x² + 8x + 1 - (10x² + 38x + 37) = 0
6x² - 30x - 36 = 0
6(x² - 5x - 6) = 0
x² - 5x - 6 = 0
x² - 6x + x - 6 = 0
x(x - 6) + 1(x - 6) = 0
(x + 1)(x - 6) = 0
x = -1 or x = 6
since x cannot be negative, therefore x = 6
Sides are (3x + 6) = 3(6) + 6 = 24 m
(x + 1) = 6 + 1 = 7 m
Diagonal = 4x + 1 = 4(6) + 1 = 25 m
Area of camp site = side * side = 24 m * 7 m = 168 m²

Step-by-step explanation:

Emily draws point C on the line segment so that the ratio of AC to CB is 3 to 1. What are the coordinates of Point C?
a. (-2,2.5)
b.(-1,2)
c.(3,0)
d.(4,-0.5)
Answer:
d.(4,-0.5)
Step-by-step explanation:
We are given that the ratio of AC to CB
AC:CB=3:1
[tex]m_1=3,m_2=1[/tex]
From given figure
The coordinates of A are (-5,4)
The coordinates of B are (7,-2)
We have to find the coordinates of C
Section formula:
[tex]x=\frac{m_1x_2+m_2x_1}{m_1+m_2},y=\frac{m_1y_2+m_2y_1}{m_1+m_2}[/tex]
Using the formula
The coordinate of point C are
[tex]x=\frac{3(7)+1(-5)}{3+1},y=\frac{3(-2)+1(4)}{3+1}[/tex]
[tex]x=\frac{16}{4},y=\frac{-1}{2}[/tex]
[tex]x=4,y=-0.5[/tex]
Hence, the coordinate of point C are (4,-0.5)

2/5 + 1/3 Can you add these fractions with the denominators they have right now?
Answer:
yes you can simplify it because both the denominators have common denominator of 15.
Answer:
Yes
Step-by-step explanation:
If the denominators are not the same, then you have to use equivalent fractions which do have a common denominator . To do this, you need to find the least common multiple (LCM) of the two denominators. To add fractions with unlike denominators, rename the fractions with a common denominator. Then add and simplify.

The height of an isosceles triangle is 12cm. The base of the triangle is 18cm. Work out the length of the equal sides
Answer:
The length of the equal sides is 15 centimeters.
Step-by-step explanation:
Since, base and height of the triangle are perpendicular to each other. In an isosceles triangle, the value of each equal length ([tex]l[/tex]), measured in centimeters, can be determined by the following Pythagorean identity:
[tex]l = \sqrt{\frac{b^{2}}{4}+h^{2}}[/tex] (1)
Where:
[tex]b[/tex] - Base of the triangle, measured in centimeters.
[tex]h[/tex] - Height of the triangle, measured in centimeters.
If we know that [tex]b = 18\,cm[/tex] and [tex]h = 12\,cm[/tex], then the value of each equal length within the isosceles triangle is:
[tex]l =\sqrt{\frac{(18\,cm)^{2}}{4}+(12\,cm)^{2}}[/tex]
[tex]l = 15\,cm[/tex]
The length of the equal sides is 15 centimeters.

If a polynomial function f(x) has roots 3 and StartRoot 7 EndRoot, what must also be a root of f(x)?
Answer:
–√(7) must also be a root of f(x)
Step-by-step explanation:
Given that the roots of an equation is 3 and √(7). This means that x = 3 or √(7). Therefore, the function is definitely going to be:
f(x) = (x – 3)(x² – 7)
This is because we are dealing with √(7) and what brought about √(7) was x² = 7.
If this is the case, we know that x² = 7 will give
x = ±√(7)
Hence, our roots are x = 3 or √(7) or –√(7). Therefore, –√(7) must also be a root of f(x).

A ball is thrown into the air from the top of a building. The height, h(t), of the ball above the ground t seconds after it is thrown can be modeled by h(t)= -16t^2+64t+80 How many seconds after being thrown will the ball hit the ground?
Answer: Also can i have brainliest?
The ball will hit the ground 5 seconds after being thrown.
Step-by-step explanation:
The correct function is: h(t)= -16t^2+64t+80
You can rewrite the Quadratic function given in the exercise with making h(t)=0. Then this is:
0= -16t^2+64t+80
Now you can simplify the equation dividing both sides by -16. So you get:
0= t^2-4t-5
To find the solution of the Quadratic equation, you can factor it. In order to do this, it is necessary to find two numbers whose sum is -4 and whose product is -5. These number would be -5 and 1.
Therefore, you get this result:
0= (t-5) (t+1)
t1=5
t2=-1
Since the time cannot be negative, you can conclude that the ball will hit the ground 5 seconds after being thrown.
