Erika is working on solving the exponential equation 50^x = 17; The solution is x = 0.7242.
What is logarithm?When you raise a number with an exponent, there comes a result.
Let's say you get
a^b = c
Then, you can write 'b' in terms of 'a' and 'c' using a logarithm as follows
[tex]b = \log_a(c)[/tex]
'a' is called base of this log function. We say that 'b' is the logarithm of 'c' to base 'a'
Erika is working on solving the exponential equation 50^x = 17;
however, she is not quite sure where to start.
The equation is
[tex]50^x = 17\\[/tex]
By taking the log both sides
[tex]log_a b = x\\\\a_x = b[/tex]
By using the base formula
[tex]log_0 y = \dfrac{logy}{log b}[/tex]
So, [tex]log_{50} 17= x\\\\[/tex]
[tex]x = \dfrac{log17}{log 50}[/tex]
x = 0.7242

Triangle DEF has vertices D(0,2) , E(2,4) , and F(4,0) . Graph the image of the triangle after a reflection across the x-axis, followed by a dilation by a scale factor of 1.5.
Answers
The attached figure represents the image of the triangle after a reflection and a dilation
How to determine the image of the triangle?The vertices are given as:
D(0,2) , E(2,4) , and F(4,0) .
The transformations are given as:
Reflection across the x-axisDilation by a scale factor of 1.5.The rule of reflection across the x-axis is
(x,y) -> (x,-y)
So, we have:
D' = (0,-2)
E' = (2,-4)
F' = (4,0)
The rule of dilation by a scale factor of 1.5 is:
(x,y) -> 1.5(x,y)
So, we have:
D'' = 1.5 * (0,-2) = (0,-3)
E'' = 1.5 * (2,-4) = (3,-6)
F'' = 1.5 * (4,0) = (6,0)

If you pull a card from a standard deck of 52 and then pull a second card without replacing the first card, you have about a ____ chance(round to nearest percent) of pulling out a face card, followed by on ace.
Answers
The probability that you pull a card from a standard deck of 52 and then pull a second card without replacing the first card is 2%
How to determine the probability?The given parameters are:
Cards = 52
Face card = 12
Ace = 4
The probability of selecting a face card is:
P(Face card) = 12/52
Now, there are 51 cards.
The probability of selecting an ace is:
P(Ace) = 4/51
The required probability is:
P = 12/52 * 4/51
Evaluate
P = 0.0181
Express as percentage
P = 1.81%
Approximate
P = 2%
Hence, the probability is 2%

Step-by-step explanation:
if you graph it, we can find out two points are 0,17 and 1,13
we can find the slope from rise/run
-4 is the slope of the line represented by the equation y + 3 = -4(x-5)
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
The equation of the line is y + 3 = -4(x-5)
We have to find slope
Let us simplify the equation to slope intercept form to find slope
y+3=-4x+20
y=-4x+17
Hence, -4 is the slope of the line represented by the equation y + 3 = -4(x-5)

Translation as Triangle A has been translated by a vector (3,-1) to now being (-2,-3).
What is translation?The process of changing the location of the image on the coordinate system will be known as the translation.
A translation in mathematics does not turn a shape; instead, it moves it left, right, up, or down. They are congruent if the translated shapes (or the image) seem to be the same size as the original shapes. They have merely changed their direction or directions.
Given that Translate Triangle A by a vector (3, -1) to give triangle B. Then, rotate your triangle B 180° around the origin to give triangle C.
Triangle A translation ⇒ (3,-1)
