Answer:

cos(A) = 12/13

Step-by-step explanation:

There are several ways to remember trigonometric functions, but my personal favorite is:

SOH - CAH - TOA

Where Sin(angle) = Opposite/Hypotenuse

Cos(angle) = Adjacent/Hypotenuse

and Tan(angle) = Opposite/Adjacent

The opposite is the side of a triangle that does not form part of the angle. E.g. for angle A the opposite is 5, for angle B the opposite is 12.

The hypotenuse is the longest side of the triangle, or the opposite in relation to the right angle (signified here by the little red box in the bottom left).

The adjacent is the side that isn't the hypotenuse, but is still next to a given angle. E.g. the adjacent for angle A is 12, and the adjacent for angle B is 5.

The cosine of angle A is the adjacent of angle A divided by the hypotenuse. The side adjacent to A is 12, and the hypotenuse is 13. Therefore, the cosine of angle A is 12/13.

Answer:

(-4,1.5)

Step-by-step explanation:

Given :-

And we need to find out the midpoint of the two points. The midpoint of two points is given by the ,

[tex]:\implies[/tex] Midpoint =( x1+x2/2 , y1+y2/2)

[tex]:\implies[/tex] Midpoint =( -5-3/2 , 5-2/2)

[tex]:\implies[/tex] Midpoint =(-8/2,3/2)

[tex]:\implies[/tex] Midpoint = (-4 , 1.5)

Here we would be using the midpoint formula to find the co-ordinates of the line segment joining the two given points.

Given points,

Answer: 90.75 mm

Step-by-step explanation:

Given

The radius of the hemisphere is 16 mm

length of the inclined sides are 20 mm

The perimeter of the figure is the sum of the length of two inclined sides and a semi-circle circumference

[tex]\Rightarrow \text{Perimeter P=}\dfrac{2\pi r}{2}+2\times 20\\\\\Rightarrow P=\pi \times 16+40\\\Rightarrow P=50.75+40\\\Rightarrow P=90.75\ mm[/tex]

Answer:

Opción b, P(2) = 0

Step-by-step explanation:

Tenemos la expresión:

P(y) = y^2 - 7*y + 10

Para encontrar el valor P(2), simplemente debemos remplazar todas las "y" en la expresión de arriba por el valor 2, asi obtenemos:

P(2) = 2^2 - 7*2 + 10 = 4 - 14 + 10 = (4 - 14) + 10 = -10 + 10 = 0

P(2) = 0

La opción correcta es b.

Answer:

10.82

Step-by-step explanation:

6^2+9^2=x

36+81=117

Square root of 117 is 10.82

The value of the given side x  in the given circle is 10.82.

We have given that,

If necessary, round your answer to the nearest tenth. O is the center of the circle. The figure is not drawn to scale.

[tex]side^2+side^2=hypotenous^2[/tex]

6^2+9^2=x^2

36+81=117

117=x^2

taking square root on both sides.

The Square root of 117 is 10.82.

Therefore the square root of the 117 is 10.82.

Step-by-step explanation:

Answer:

a right because it has kind of a 90 angle

Step-by-step explanation:

Answer:

Company A:

150 x 3 = $450

6/100 x 150 = $9

450 + 9 = $459

Company B:

3.10 x 150 = 465

4/100 x 150 = 6

465 + 6 = $471

Company C:

3.20 x 150 = $480

Now the order (Answer):

A(459), B(471), C(480)

Answer:

13. 1/3

14. 1/20

15. 9/20

16. 9/200

17. 253/25

18. 39/10

Answer:

V = pi*r^2*h

V = 150 m^3

h = 8 m

150 = pi*r^2*8

Solve for r (the radius) then multiply by 2 to obtain the diameter.Only, this is a cone, not a cylinder.

V = 1/3 pi r^2 h

Diameter of the cone is 15 m. So, option D is correct.

Solid shapes are defined as the three-dimensional objects that are described by the three dimensions length, breadth and height.

Here,

Volume of the cone is given by,

 V = 150[tex]\pi[/tex] m³

Height of the cone, h = 8 m

We know, the equation for the volume of a cone is,

V = 1/3[tex]\pi[/tex]r²h

where r is the radius and h is the height of the cone.

So,

(1/3) [tex]\pi[/tex]r²h = 150[tex]\pi[/tex]

r²x 8 = 3 x 150 = 450

r² = 450/8

r² = 56.25

r = 7.5 m

Therefore, diameter of the cone,

d = 2r

d = 2 x 7.5

d = 15 m

Hence,

Diameter of the cone is 15 m.
