A pigeon was sitting 40 feet from the base of a telephone pole and flew 50 feet to reach the top of the pole. How tall is the telephone pole?
Answer:
90 feet
Step-by-step explanation:
40 + 50= 90 feet.
40 feet from the base is 40 feet high and 50 feet up is this equation.
Hope it helps sry if I’m wrong
Answer:
24 ft
Step-by-step explanation:
50 ^ 2 - 40 ^ 2 = b^2
2500 - 1600 = b^2
900 = b^2
√900 = √b^2
24 = b
Translate Triangle A by vector (3, -1) to give triangle B.
Then, rotate your triangle B 180° around the origin to give triangle C.
Describe fully the SINGLE transformation that maps triangle A onto triangle C.
Answer:
Translation as Triangle A has been translated by vector (3,-1) to now being (-2,-3)
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)
The second translation = (-2,-3).
Therefore, the translation as Triangle A has been translated by a vector (3,-1) to now being (-2,-3).

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.
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)

pleeeeeeeeeeeeeeeeas FAST !!!!! i need help if a/b = (-7/9)^8 / (-7/9)^6 find the value of (a/b)^2.
Answer:
(-7/9)^4 = 2401/6561
Step-by-step explanation:
The rules of exponents apply.
(a^b)/(a^c) = a^(b-c) . . . . . quotient rule
(a^b)^c = a^(bc) . . . . . . . . power rule
__
value of a/bThe first rule of exponents shown above helps us find the value of a/b.
[tex]\dfrac{a}{b}=\dfrac{\left(\dfrac{-7}{9}\right)^8}{\left(\dfrac{-7}{9}\right)^6}=\left(\dfrac{-7}{9}\right)^{8-6}=\left(\dfrac{-7}{9}\right)^2[/tex]
value of (a/b)^2The second rule of exponents shown above tells us how to find the square.
[tex]\left(\dfrac{a}{b}\right)^2=\left(\left(\dfrac{-7}{9}\right)^2\right)^2=\left(\dfrac{-7}{9}\right)^{2\times2}\\\\\boxed{\left(\dfrac{a}{b}\right)^2=\left(\dfrac{-7}{9}\right)^4=\dfrac{2401}{6561}}[/tex]

hint: use the change of base formula: log base b of y equals log y over log b.
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

What is the slope of the line represented by the equation y + 3 = -4(x-5)?
OA. 3
OB. 4
O C. -3
OD. -4
Answer:
-4
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)
