Answer:

$y=-\cos x$

Step-by-step explanation:

The given trigonometric graph is symmetric about the y-axis.

This means it is a cosine function.

The basic is symmetric about the y-axis and has a y-intercept of 1.

Its range is $-1\le y\le1$

Since the given graph has y-intercept at -1 with the same range, it is the parent cosine function reflected in the x-axis.

Therefore its equation is $y=-\cos x$

The container hold 1/2 gallon of water. It is 3/4 full. How many gallons of water are in the container?

Olegator [25]

Based on the capacity of the container and the capacity currently being used, the amount of water in the container is 3/8 gallons. 

The container is capable of holding 1/2 gallons of water.

If it is holding 3/4 of that 1/2 gallons, the amount of water it would be holding is:

= Capacity of container x Percentage full

= 1/2 x 3/4

= 3/8 gallons of water

In conclusion, the container is currently holding 3/8 gallons of water.

Answer: $1\dfrac13$ cups of pineapple juice .

Step-by-step explanation:

Equation of direct proportion between x and y:

$\dfrac{x_1}{y_1}=\dfrac{x_2}{y_2}$

As per given,

Let x = quantity of pineapple juice and y = quantity of orange juice.

$x_1=\dfrac13\$ , $y_1=\dfrac34$ , $y_2=3$

Put these values in an equation we get

$\dfrac{\dfrac13}{\dfrac34}=\dfrac{x_2}{3}\\\\\Rightarrow\ \dfrac{4}{9}=\dfrac{x_2}{3}\\\\\Rightarrow\ x_2=3\times\dfrac{4}{9}=\dfrac{4}{3}\\\\\Rightarrow\ x_2=1\dfrac13$

Hence, he needs $1\dfrac13$ cups of pineapple juice .

3 spheres of diameter 6cm,8cm and 10cm are melted to form a single sphere .find the diameter of the sphere.

julia-pushkina [17]

Answer:

Step-by-step explanation:

6/2=3 cm is the radius V(4/3πr³) = 4/3.π.27…(1)

8/2= 4 cm is the radius and V = 4/3.π.64…..(2)

10/2=5 cm is the radius and V = 4/3.π.125…(3)

The Total Volume is the addition of (1)+(2)+(3) or 4/3π (27+64+125) or New volume is 4/3.π.(216) cm³ and therefore...

The radius of the New Solid Sphere is Cube Root of 216 (r³) = √6.6.6 or r = 6 cm and the diameter is 6.2 = 12 cms.

12 cms answer. Brainlist please?
