what is the approximate value of x in the exponential 4^x=14?
We know 4² = 16 , 4¹= 4
In this case we have :-
[tex] {4}^{x} = 14[/tex]
and we have to find the value of x
14 is less than 16 so x will be less than 2
14 is greater than 4 so x will be greater than 1
we can find the value of
[tex] {4}^{1.5} = {4}^{ \frac{3}{2} } \\ { (\sqrt{4}) }^{3} = {2}^{3} = 8[/tex]
so we can say 14 is much larger than 8 which means x will be much larger than 1.5
so according to above ideas we can say our answer is 2nd option which is 1.9037 is our answer
[tex]x \approx1.9037[/tex]
[tex]~~~~~~~4^x = 14 \\\\\implies \ln 4^x = \ln 14\\\\\implies x \ln 4 = \ln 14\\ \\\implies x = \dfrac{\ln 14}{ \ln 4}\\\\\implies x \approx 1.9037[/tex]

Jerry boards a Ferris wheel from the bottom of the wheel (the 6 o'clock position) and the Ferris wheel rotates counterclockwise. The center of the wheel is 30 feet from the ground and the radius if the wheel is 25 feet.
Using a sine function, describe a function g that represents the height above the ground (in feet) in terms of the time since the Ferris wheel began rotating if the Ferris wheel rotates at a speed of 2 radians per second.
O9(0)-25 cos(+)+30

function g that represents the height above the ground (in feet) in terms of the time since the Ferris wheel began rotating if the Ferris wheel rotates at a speed of 2 radians per second is g(t) = 25cos(2t) feet+30
What is angle?An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.
The height g(t) above the center after t minutes is given by
g(t) = 25cos(r(t))
g(t) = 25cos(2t) feet+30

≅ sign means that the triangles are congruent, which means they both have the same shape and the same size.
When comparing congruent shapes, inspect the order in which the vertices are given in the statement.

Answer:
D 36.6
Step-by-step explanation:
Here, there is a triangle inscribed inside of a semicircle where the triangle is unshaded and the remained of the semicircle is shaded and we want to find the area of that shaded untouched area of the semicircle.
To do so we must find the area of the two shapes individually and then subtract the area of the triangle from the area of the semi circle as the triangle is what is uncovering the semicircle.
Finding the area of the semicircle
Area of a semicircle = (πr²)/2 where r = radius
Here we are given the diameter of the semicircle which is 13cm. We can easily convert the diameter to radius by dividing it by 2 as the radius is equal to half the diameter
Radius = 1/2 diameter , so radius = 13 / 2 = 6.5cm
We have A = πr²/2
==> plug in radius or r = 6.5
A = π(6.5)²/2
==> simplify exponent
A = π(42.25)/2
==> multiply π and 42.25 ( note that π = 3.14 approximately
A = 132.665/2
==> divide 132.665 by 2
A = 66.366
So the area of the semicircle is 66.366cm²
Finding the area of the triangle
The area of a triangle can be calculated by dividing the product of the base length and height ( formula = bh / 2 where b = base length and h = height )
Here the base length appears to be 5cm and the height appears to be 12cm so b = 5 and h = 12
So we have A = bh/2
==> plug in b = 5 and h = 12
A = (12)(5)/2
==> multiply 12 and 5
A = 60 / 2
==> divide 60 by 2
A = 30
So the area of the triangle is 30cm²
Subtracting the area of the triangle from the area of the semicircle
Finally to find the area of the shaded region we subtract the area of the triangle from the area of the semicircle
We have area of triangle = 30cm² and area of semicircle = 66.366
So area of shaded region = 66.366 - 30 = 36.366

Which one of these is not a step used when constructing an inscribed equilateral triangle using technology?
A. Create a circle using the center with given point tool.
B. Connect the point with a line through the center of the circle.
C. Create another circle with the same radius as the original.
D. Connect the two circles together using the compass tool.
Answer:
The answer is D
Step-by-step explanation:
Draw the point at which your circle will be centered.
Use a compass to draw a perfect circle centered at point O.
Use a ruler to draw a vertical line straight through point O.
Draw the points at which the line intersects the circle.
Draw a second circle. This circle will be centered at Point W and the radius will extend to Point O.
Mark both places where the two circles intersect. Label the point on the left "Point Y" and the point on the right "Point Z".
Connect points X, Y, and Z using a ruler or straight edge.

Answer:
17Step-by-step explanation:
SINCE THE LINES ARE PARALLEL THEN ANGLE A AND ANGLE B ARE COREESPONDING TO EACH OTHER.A = 7x + 24 B= 3x+ 92A=B7x + 24 = 3x + 927x - 3x = 92 - 24
4x = 68
x = 68 / 4
x =17
Answer:
143
Step-by-step explanation:
These are corresponding angles meaning they are congruent. So we just have to set them equal to each other and solve for x. Then plug in x.
7x + 24 = 3x + 92
subtract 3x from both sides
4x + 24 = 92
subtract 24 from both sides
4x = 68
divide both sides by 4
x = 17
Now plug in x to angle A, which is 7(17) + 24
119 + 24
then add
you get:
