The length of side p of the triangle rounded to the nearest tenth is 7.5.

The cosine rule relates the lengths of the sides of a triangle to the cosine of one of its angles.

It is expressed as;

p = √( n² + m² - ( 2nm × cosθ ) )

Given the figure in the diagram;

Plug the values into the above formula and simplify.

p = √( n² + m² - ( 2nm × cosθ ) )

p = √( (11)² + (13)² - ( 2 × 11 × 13 × cos( 35 ) ) )

p = √( 121 + 169 - ( 286 × cos( 35 ) ) )

p = √( 290 - ( 286 × cos( 35 ) ) )

p = √( 290 - 234.27748  )

p = √( 290 - 234.27748  )

p = √55.72252

p = 7.5

Therefore, the value of p is 7.5.

To solve the equation, you can use the following steps:

Start by isolating the absolute value expression on one side of the equation:

-5|x+3| = 18

Now, since the absolute value is positive, it has two solutions:

x + 3 = -18 or x + 3 = 18

Solving for x in each case:

x = -21 (if x + 3 = -18) or x = 15 (if x + 3 = 18)

So the two solutions to the equation are x = -21 and x = 15.

The rate of change of the volume is 871.2 ft³/sec

Rate of change of volume is the change in volume with time.

The rate of change of radius is 6 feet per second.

rate of change in volume = dv/dt

rate of change in radius = dr/dt

to find radius of the sphere;

V = 4/3 πr³

163 = 4/3 x3.14r³

r³ = 163× 3)/4×3.14

r³ = 488/12.56

r³ = 38.85

r = 3.4 feet

therefore

dr/dt = 1/4πr² × dv/dt

= 6 = 1/4×3.14× 3.4² × dv/dt

dv/dt = 6×4× 3.14× 3.4²

dv/dt = 871.2 feet³ per second

The system of equations is solved and the value of x = 5

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the first equation be represented as A

Now , the value of A is

The number of degrees moved by the minute hand of a clock in 2/3hours is 240°

Angles around a point describes the sum of angles that can be arranged together so that they form a full turn. Angles around a point add to 360 °.

The hand of minute will move 360° to complete an hour.

If a full round will make angle at a point. Which is 360°

Therefore 2/3 of an hour will give an angle of 2/3 of 360°

= 2/3 × 360

61.025 meters is the maximum height obtained by the baseball

A relation is a function if it has only One y-value for each x-value.

The length of time and the maximum height can be found by finding the vertex of the parabola.

h(t) = -4.9t² + 34.3t + 1

x = -b/2a

t = -34.3/-9.8

t=3.5

Now plug in t value in the function

h(3.5)= -4.9(3.5)² + 34.3(3.5)+ 1

=-4.9(12.25)+120.05+1

=-60.025+120.05+1

This gives

Area = 1/2π(10/2)²

Evaluate

Area = 25/2π

For the big semicircle, we have

Area = 1/2π(D/2)²

Area = 1/2π(20/2)²

To evaluate [tex]f(g(3))[/tex], we need to first evaluate g(3), then evaluate f(g(3)).

[tex]$$g(3)=7 \cdot 3^2+6 \cdot 3+2=65$$[/tex]

A relationship between a number of inputs, each of which has an output, is known as a function. A function is, to put it simply, a relationship between inputs that are individually connected to exactly one output. There are two domains or scopes for each function. f is typically used to represent functions (x). The input is x. Y = f is a common way to represent the function (x).

To evaluate [tex]f(g(3))[/tex], we need to first evaluate g(3), then evaluate f(g(3)).

[tex]$$g(3)=7 \cdot 3^2+6 \cdot 3+2=65$$[/tex]

So

[tex]f(g(3))=f(65)=\frac{1}{2} \cdot 65-4=\frac{1}{2} \cdot 65-4=28[/tex]

To evaluate [tex]g(f(8))[/tex], we need to first evaluate [tex]f(8)[/tex], then evaluate [tex]f(8)[/tex].

[tex]f(8)=\frac{1}{2} \cdot 8-4=2\\\\g(f(8))=g(2)=7 \cdot 2^2+6 \cdot 2+2=46\\g(f(8))=46[/tex]

[tex]g\left(\frac{1}{8}\right)=7\left(\frac{1}{8}\right)^2+6 \cdot \frac{1}{8}+2=\frac{121}{8}+\frac{3}{2}+2=\frac{135}{8}[/tex]

[tex]f\left(g\left(\frac{1}{8}\right)\right)=f\left(\frac{135}{8}\right)=\frac{1}{2} \cdot \frac{135}{8}-4=\frac{135}{16}-4=\frac{135-64}{16}=\frac{71}{16}\\f\left(\frac{1}{2}\right)=\frac{1}{2} \cdot \frac{1}{2}-4=-4[/tex]

Step-by-step explanation:

Step 1: Setup

Set up your multiplication problem like this:

             9 3

     x       2 6

Step 2: Multiply

3 x 6 = 18. Put 8 below the line and 1 as a reminder on top:

             1  

             9 3

     x       2 6

               8

Step 3: Multiply

6 x 9 = 54. Take 54 and add 1 from the previous step to get 55. Enter 55 at the bottom:

             9 3

     x       2 6

           5 5 8

Step 4: Add 0

Enter a 0 at the bottom right as a place holder, because you now move over one digit:

             9 3

     x       2 6

           5 5 8

     +         0

Step 5: Multiply

2 x 3 = 6. Put 6 below the line and 0 as a reminder on top:

             0  

             9 3

     x       2 6

           5 5 8

     +       6 0

Step 6: Multiply

2 x 9 = 18. Take 18 and add 0 from the previous step to get 18. Enter 18 at the bottom:

             9 3

     x       2 6

           5 5 8

     +   1 8 6 0

Step 7: Add to get an answer

Add up the bottom two numbers (558 + 1860 = 2418) to get the answer:

Step-by-step explanation:

To find coterminal angles, add/subtract integer multiples of [tex]360^{\circ}[/tex].

[tex]-490^{\circ}+360^{\circ}=-130^{\circ}\\\\-130^{\circ}+360^{\circ}=230^{\circ}[/tex]

An angle θ that is coterminal with −490∘ and lies between 0∘ and 360∘ is 130∘.

To find an angle θ that is coterminal with −490∘ and lies between 0∘ and 360∘, we can use the concept of coterminal angles.

Coterminal angles are angles that have the same initial and terminal sides when drawn in standard position. To find a positive coterminal angle with a negative angle, we can add 360 degrees to the negative angle until we get an angle within the desired range (0∘ to 360∘).

Let's find the positive coterminal angle:

θ = -490∘ + 360∘

θ = -130∘

So, an angle θ that is coterminal with −490∘ and lies between 0∘ and 360∘ is 130∘.

Step-by-step explanation:

The size of the angle between EM and the base of the prism is equal to 28.5°.

First of all, we would determine side length MA based on the ratio between side lengths DM and MA as follows;

DM : MA = 3 : 4

Total side parts = 14 cm

(3 + 4) parts = 14 cm

7 parts = 14 cm

1 part = 2 cm

Therefore, side length MA = 2 × 4 = 8 cm.

By applying Pythagorean's theorem to right triangle MAB, we have the following:

c² = a² + b²

Where:

a, b, and c represents the side lengths of a right triangle.

c² = 8² + 14²

c² = 260

c = √260

c = 16.1245 cm.

By applying tan trigonometry to right triangle AEB, we have:

tanθ = opposite/adjacent

opposite = tan32° × 14

opposite = 8.7482 cm.

By applying tan trigonometry to right triangle EMB, we have:

tanθ = opposite/adjacent

θ = tan⁻¹(opposite/adjacent)

θ = tan⁻¹(8.7482/16.1245)

θ = tan⁻¹(0.5425)

θ = 28.5°.
