Answer: 4.7

Step-by-step explanation:

Use Soh Cah Toa

$sin \theta=\dfrac{opposite}{adjacent}\\\\\\sin(58^o)=\dfrac{4.0}{x}\\\\\\x=\dfrac{4.0}{sin(58^o)}\\\\\\x=4.7$

Answer:

The value of x = 4.7

Step-by-step explanation:

From the figure we can see aright triangle with height = 4.0 and one angle is 58°

Points to remember

Trigonometric ratios

Sin θ = Opposite side/Hypotenuse

To find the value of x

Sin 58 = Opposite side/Hypotenuse

= 4/x

x = 4/Sin (58)

= 4/0.848

= 4.71 ≈ 4.7

Therefore the value of x = 4.7

Determine if the function is one-to-one. (5 points)

photoshop1234 [79]

Answer: NO

Step-by-step explanation:

In order for the function to be one-to-one, it must pass the vertical line test AND the horizontal line test.

The vertical line test is where you draw a vertical line anywhere and the line will not intersect the graph more than one time. In other words, the function cannot contain a duplicate x-value.

The horizontal line test is where you draw a horizontal line anywhere and the line will not intersect the graph more than one time. In other words, the function cannot contain a duplicate y-value.

The graph provided passes the vertical line test but fails the horizontal line test. One example is that there are two x-intercepts.

The composite figure is made up of a triangular prism and a pyramid. The two solids have congruent bases.

kolezko [41]

The correct question is
The composite figure is made up of a triangular prism and a pyramid. The two solids have congruent bases. What is the volume of the composite figure?

the complete question in the attached figure

we know that
[volume of a cone]=[area of the base]*h/3
[area of the base]=22*10/2-------> 110 units²
h=19.5 units
[volume of a cone]=[110]*19.5/3------> 715 units³

[volume of a triangular prism]=[area of the base]*h
[area of the base]=110 units²
h=25 units
[volume of a a triangular prism]=[110]*25------------> 2750 units³

[volume of a the composite figure]=[volume of a cone]+[volume of a a triangular prism]

[volume of a the composite figure]=[715]+[2750]-------> 3465 units³

the answer is
The volume of a the composite figure is 3465 units³

A new crew of painters can paint a small apartment in 12 hours. an experienced crew can paint the small apartment in 6 hours. ho

Yakvenalex [24]

This is the concept of proportionality, we are required to calculate for the number of hours two crews can use to paint the house altogether.
Here proceed as follows;
number of hours new crew can paint=12 hrs
portion of work painted by new crew in 1 hour= 1/12

number of hours experienced crew can paint=6 hours
Portion of work painted by experienced crew in 1 hour=1/6

Portion of work painted by the two crews altogether in 1 hour will be:
1/6+1/12=1/4

thus the total amount of hours that the two painters will take to paint will be:
4 hours

What is the sum of the angle measures of a 37 gon?

Airida [17]

Answer:

The sum of the interior angles with n number of sides is solved through the equation,

S = 180 x (n - 2)

For 37 - gon,

S = 180 x (37 - 2) = 6300

Thus, the sum of the interior angles of a 37-gon is 6300°
