Answer:

see the attachment

Step-by-step explanation:

f(x) = x defines a line with a slope of 1 (upward to the right). Only the bottom two graphs have such a line.

The inequality symbol ≥ means the function has this definition for the case when x = 1. That is, f(x) ≥ x for x≥1 means f(1) = 1. The solid dot means that point on the graph is a point that satisfies the function definition.

The graph at lower right is a graph that includes the point f(1) = 3, which is not the same function as the one in the problem statement.

What is the number in scientific notation? 0.0765

devlian [24]

Answer:

$7.65 * 10^{-2}$ is scientific notation of 0.0765

Step-by-step explanation:

For scientific notation , follow the following notation:

$a * 10^{b}$ -------->(equation 1)

Let, $a^{'} = 0.0765$

In standard form

$a = 7.65$

As decimal point move 2 places from left to right, therefore

b = -2

Put the value of 'a' and 'b' in (equation 1)

$7.65 * 10^{-2}$ is scientific notation of 0.0765

If a sphere and a cone have the same radius and height how is the volume of a sphere related to the volume of a cone?

lorasvet [3.4K]

Answer:

The volume of the silo is about 142.3 cubic meters. Try It! The volume of a sphere is twice the volume of a cone that has the same circular base and height. The formula for the volume of a sphere with radius r is V= r3.

Step-by-step explanation:

Notice that if a cone and a sphere have equal radius, and if the cone has a height equal to its radius, then the cone will fill the sphere exactly four times. This means that the volume of the sphere is $4 times the volume of the cone.

The value of acceleration due to gravity is greater in terai than in mountain. In terai region the radius of earth is less as it lies close to the centre of the earth. Thus, the value of g is more in terai region.

David is making rice for his guests based on a recipe that requires rice, water, and a special blend of spice, where the rice-to

Travka [436]

Answer:

Price of rice per gram = $ 0.006 per gram or 0.6 cents per gram .

Step-by-step explanation:

Given: David wants to make 10 servings, where each serving has 75 grams of rice.

Total quantity of rice required = 10 x 75 = 750 grams

Overall, David spends 4.50 dollars on rice.

i.e. cost of 750 grams of rice = 4.50 dollars

Price of rice per gram =(cost of 750 grams of rice ) ÷ 750

= (4.50 dollars ) ÷ 750

= $ 0.006 per gram.

Price of rice per gram = $ 0.006 per gram.
