Temka [501]

The options are H,H,T or T,T,H

HHT: 1/2 x 1/2 x 1/2 = 1/8

TTH: 1/2 x 1/2 x 1/2 = 1/8

HHT or TTH: 1/8 + 1/8 = 2/8 = 1/4

Answer: 1 out of 4 = 1/4 = 25%

A lab technician has to fill the tank given below. <br> Find it’s volume .

wel

Answer:

The volume of the cylinder shown in the figure is 628 cube meters

Step-by-step explanation:

Given figure is about cylinder

The height of the cylinder = h = 8 meters

The radius of the base of cylinder = r = 5 meters

Now, let The volume of cylinder = V m³

So, The volume of cylinder is given as V = $\pi$ ×r²×h

where r is the radius of its base

And h is the height of cylinder

The value of $\pi$ = 3.14

So, V = $\pi$ × r² × h

Or, V = 3.14 × (5)² × 8

Or, V = 3.14 × 25 × 8

or, V = 628 m³

So, The volume of cylinder = V = 628 m³

Hence The volume of the cylinder shown in the figure is 628 cube meters Answer

PLEASE HELP ASAP!!

Fed [463]

Answer: The missing statements are,

In first blank: ∠2≅∠1

In second blank: AC≅AC

In third blank: Reflexive

Step-by-step explanation:

Since, The hypotenuse angle theorem states that if the hypotenuse and an acute angle of one right triangle are congruent to the hypotenuse and an acute angle of another right triangle, then the two triangles are congruent to each other.

Here, given:

∠D and ∠B are right angles.

DC ║ AB

Prove: Δ ADC ≅ Δ CBA

Statement Reason

1.∠D and ∠B are right angles 1. Given

2. ∠2 ≅ ∠1 2. If lines are parallel then interior angles

are equal

3. AC≅AC 3. Reflexive

4.Δ ADC ≅ Δ CBA 4. Hypotenuse angle theorem

For the following exercises, find (f ∘ g)(x) and (g ∘ f)(x) for each pair of functions.

Rufina [12.5K]

Answer:

The value of $(f \circ g)(x)$ is 17-18x and $(g \circ f)(x)$ is -7-18x.

Step-by-step explanation:

It is given in the question functions f(x) as 3x+2 and g(x)=5-6x.

It is required to find $(f \circ g)(x)$ and $(g \circ f)(x)$ .

To find $(f \circ g)(x)$ , substitute g(x) for x in f(x) and simplify the expression.

To find $(g \circ f)(x)$ , substitute f(x) for x in g(x) and simplify the expression.

Step 1 of 2

Substitute g(x) for x in f(x) and simplify the expression.

$\begin{aligned}&(f \circ g)(x)=f(5-6 x) \\&(f \circ g)(x)=3(5-6 x)+2 \\&(f \circ g)(x)=15-18 x+2 \\&(f \circ g)(x)=17-18 x\end{aligned}$

Step 2 of 2

Substitute f(x) for x in g(x) and simplify the expression.

$\begin{aligned}&(g \circ f)(x)=g(3 x+2) \\&(g \circ f)(x)=5-6(3 x+2) \\&(g \circ f)(x)=5-18 x-12 \\&(g \circ f)(x)=-7-18 x\end{aligned}$
