Triangle DAN is graphed on the set of axes below.
The vertices of ADAN have coordinates D(-6,-1),
A(6,3), and N(-3,10).
Answers
The area of the triangle DAN is 60 square units if the vertices of ΔDAN have coordinates D(-6,-1), A(6,3), and N(-3,10) option first is correct.
What is the triangle?The triangle can be defined as a three-sided polygon in geometry and it consists of three vertices and three edges. The sum of all the angles inside the triangle is 180°.
We have triangle DAN which is graphed on the set of axes.
The vertices of ΔADN have coordinates:
D(-6, -1), A(6, 3), and N(-3, 10)
We can find the area of the triangle using the coordinates of the triangle such as:
[tex]\rm Area \ of \ the \ triangle = \frac{1}{2} [x_1(y_2-y_3)+x_2(y_3-y_1)+x_3(y_1-y_2)][/tex]
Let's denote the coordinates N(-3, 10), D(-6, -1), andA(6, 3), and with
[tex]\rm (x_1, y_1), (x_2, y_2), \ and \ (x_3,y_3)[/tex] respectively.
Put these points in the above expression, we get:
[tex]\rm Area \ of \ the \ triangle = \frac{1}{2} [-3(-1-3)-6(3-10)+6(10-(-1))][/tex]
[tex]\rm Area \ of \ the \ triangle = \frac{1}{2} [-3(-4)-6(-7)+6(11)][/tex]
[tex]\rm Area \ of \ the \ triangle = \frac{1}{2} [12+42+66][/tex]
[tex]\rm Area \ of \ the \ triangle = \frac{1}{2} [120][/tex]
Area of the triangle = 60square units
Thus, the area of the triangle DAN is 60 square units if the vertices of ΔDAN have coordinates D(-6,-1), A(6,3), and N(-3,10) option first is correct.

Answers
Answer:
16800
Step-by-step explanation:
142^2 (142 squared) is 142 x 142, which is 20164. 58 squared is 3364, and 20164 - 3364 is 16800. if you need a more in depth explanation just let me know!
Answer:
16800
Step-by-step explanation:
(142)² – (58)²
Follow the Pemdas order of operation;
Calculate the exponents first;
(142)^2=20164
=20164-(58)^2
(58)^2=3364
=20164-3364
Add and subtract( left to right)
20164-3364
=16800

the volume of a sphere is 4851 cubic cm find its diameter
Answers
Answer:
The diameter is 21 cm
Step-by-step explanation:
The formula for the volume of a sphere is V = (4/3)πr³, or (in terms of the diameter) V = (4/3)π(d/2)³. This simplifies to
4πd³ πd³
V = ----------- = -----------
3·8 6
Now equate V = (πd³/6) to 4851 cm³. We must first solve this for d³ and then take the cube root of the result:
πd³ = 4851(6) = 29106.
Dividing this result by π yields 9264.7,
and taking the cube root of this is 21. The diameter is 21 cm

A central angle of a circle measures π/3 radians.The length of the minor arc intercepted by this central angle is 7 inches. Find the length of the radius of the circle.
Answers
9514 1404 393
Answer:
6.68 in
Step-by-step explanation:
The length of an arc is given by ...
s = rθ . . . . θ in radians
Then the radius is ...
r = s/θ
r = (7 in)/(π/3) = 21/π in ≈ 6.6845 in
The radius of the circle is about 6.68 inches.
Answer:
Solution :-Angle of circle = π/3 r
Length of minor arc = 7 in
Now
We know that
Radius = Length/Angle
Radius = 7/(π/3)
Radius = 7/π × 3
Radius = 21/π

After how many students would it be better to hire Band A?
Answers
Answer:
After 200 students, it would better to hire Band A
Step-by-step explanation:
350+ 1.25x = 600
1.25x = 250
x = 200
at 200 students the cost is the same for Band A and Band B
at 201 students Band A will be cheaper then Band B
