PLEASE HELP!!!

Answer:  

(-1/2,1/2)

Step-by-step explanation:

Normally for sinx amplitude is 2 (1 +1). In the case when it is half sine amplitude is halved, therefore 0.5 +0.5 = 1 Paramers alpha = 2x does not matter because it only stretches the graph horizontally.

Step-by-step explanation:

We're trying to find what 20% of 205 is so:

We start by converting 20% to a fraction :

20% = 1/5

Then we have

20% of 205 = 1/5 x 205 = 1/5 x 205/1 = 205/5

Notice that 205 was rewritten as the fraction 205/1, and that to multiply two fractions together, you simply multiply the numerators and denominators.

In order to find the simplest form of 205/5 we cancel out the greatest common divisor of 205 and 5, which is 5:

205/5 = 41/1  

So there are 41 5th graders

Answer:

565.49 or if rounded to the nearest tenth, 565.5

Explanation:

The formula for finding the volume of a cone is V=1/3Bh

B = pi times the radius squared

h = height

Substitute 6 for r and 15 for h.

V= 1/3·[tex]\pi[/tex]·([tex]6^{2}[/tex])·15

Multiply.

V= 565.49 or 565.5 rounded to the nearest tenth.

Answer:

Obtuse triangle.

Step-by-step explanation:

The rule to know what type of triangle it is, you do A^2 + B^2 and if it is less than C^2, then it is obtuse. If it is equal, then it is right, and if it is more than, it is acute.

Do this equation fo 7, 8, and 12

7^2 + 8^2 =? 12^2

49 + 64 =? 144

113 < 144

113 is less than 144 which means that it is an obtuse triangle

Answer:

Step-by-step explanation:

The vertex would be the highest/lowest point so lets factor this first

when we factor we get

2(x^2+6x+8)

2(x+4) (x+2)

Using zero product property we find the 2 x values and x intercepts are

-4 and -2

the middle point of these points is -3

Substitute -3 for x and solve

2(-3+4) (-3+2)

2 * 1 *  -1

2*-1

-2

(-3,-2) is the vertex

4 + x=15

Step-by-step explanation:

x is unknown

so we are adding 4 and x to equal 15

Answer:

La segunda montaña más alta del mundo tiene 8611 metros.

Step-by-step explanation:

La montaña más alta del mundo es Everest cuya altura es de 8.848m.

La altura de la segunda montaña más alta es de 2hm 3dam y 7m menos. Para calcular la altura que tiene la segunda montaña más alta del mundo, debes realizar primero un cambio de unidades sabiendo que

Entonces podes aplicar las siguientes reglas de tres simple:

Si 1 hm equivale a 100 m, 2 hm equivale a ¿Cuántos metros?

[tex]metros=\frac{2 hm*100 m}{1 hm}[/tex]

metros= 200

Si 1 dam equivale a 10 m, 3 dam equivale a ¿Cuántos metros?

[tex]metros=\frac{3 dam*10 m}{1 dam}[/tex]

metros=  30

Entonces, la altura de la segunda montaña más alta es de 200 m+30 m+ 7 m menos que el Everest. Esto es, 237 metros menos que la montaña más alta del mundo. Entonces:

8848 metros - 237 metros= 8611 metros

La segunda montaña más alta del mundo tiene 8611 metros.

Answer:

Speed in miles per hour = 45 miles per hour

Step-by-step explanation:

Given:

Distance cover by Mrs Perez = 33.75 miles

Time taken by Mrs Perez = 3/4 hours = 0.75 hour

Find:

Speed in miles per hour

Computation:

Speed = Distance cover / Time taken

Speed in miles per hour = Distance cover by Mrs Perez / Time taken by Mrs Perez

Speed in miles per hour = 33.75 / 0.75

Speed in miles per hour = 45 miles per hour

Actually Welcome to the concept of Isosceles triangles.

They have two sides equal to each other, so we get as,

==> 3x + 3 = 2x + 8

==> 3x - 2x = 8-3

==> x = 5

hence the length of AC = 5 units.

Answer:

AC = 5

Step-by-step explanation:

here's your solution

=> This is a isosceles triangle

=> both sides are equal.

=> AB = CB

=> 3x + 3 = 2x + 8

=> 3x - 2x = 8 - 3

=> x = 5

so, AC = 5

Answer:

base = 8cm

height = 6cm

Step-by-step explanation:

formula for area of triangle: A = 1/2×b×h

8×6 = 48

48×1/2 = 24

Answer = 24 square centimeters

Please note that I'm assuming the base is the longest side since there is no number given for the base or the height.

Answer:

The first click beetle reaches a maximum height of 2.25 feet. From the graph, you can see that the second click beetle reaches a maxium height of between 1.5 and 1.6 feet. So, the first click beetle went higher.

A beetle reaches a maximum height of 2.25 meters after 2,25 seconds

The function is given as:

h(t)=-16t^2+12t

Differentiate

h'(t)= -32t + 12

Set to 0

-32t + 12 = 0

Add 32t to both sides

32t = 12

Divide both sides by 32

t = 0.375

Substitute t = 0.375 in h(t)

h(0.375) = -16 * 0.375^2 + 12 * 0.375

Evaluate

h(0.375) = 2.25

The above means that a beetle reaches a maximum height of 2.25 meters after 2,25 seconds
