Triangle DEF is similar to triangle ABC. What is the length of segment EF? (HINT use scale factor) (Leave answer as a fraction)
We have been given two similar triangles. We are asked to find the length of segment EF.
We know that corresponding sides of similar triangles are proportional, so we will use proportion to solve our given problem.
[tex]\frac{EF}{DF}=\frac{BC}{AC}[/tex]
Upon substituting measure of our given side lengths, we will get:
[tex]\frac{EF}{1}=\frac{5}{13}[/tex]
[tex]EF=\frac{5}{13}[/tex]
Therefore, the length of segment EF is [tex]\frac{5}{13}[/tex] units.
x squared + 12x +3 = 7 solve by completing the square
Answer:
x = -6 ± 2sqrt(10)
Step-by-step explanation:
x^2 + 12x+3 = 7
Subtract 3 from each side
x^2 +12x = 4
Take the coefficient of x
12
Divide by 2
12/2 = 6
Square it
6^2 =36
Add this to each side
x^2 +12x +36 = 4+36
(x+6)^2 = 40
Take the square root of each side
sqrt((x+6)^2) =± sqrt(40)
x+6 = ± sqrt(40)
x+6 = ± sqrt(4)sqrt(10)
x+6 =± 2sqrt(10)
Subtract 6 from each side
x+6-6 = -6 ± 2sqrt(10)
x = -6 ± 2sqrt(10)
Answer:
(x + 6)² = 40 → x = ±2√10 - 6
Step-by-step explanation:
x²+12x+3=7 can be solved by completing the square
To do so we must first find the term we are adding to both sides of the equation by using [tex](\frac{b}{2} )^2}[/tex]
In this case, our b is 12, so plugging this into the formula we get [tex](\frac{12}{2} )^{2} =6^{2} =36[/tex]
We first need to subtract the 3 from both sides of the equation to get x²+12x=4
We then can add the 36 to both sides of the equation: x² + 12x + 36 = 4 + 36 → x² +12x + 36 = 40
Now we are able to factor the left side of the equation to get (x + 6)² = 40
To solve for x we need to take the square root of both sides [tex]\sqrt{(x+6)^{2} } =\sqrt{40}[/tex] to get x + 6 = ±2√10
Then we need to subtract 6 from both sides to get x = ±2√10 - 6

What is the probability of tossing a coin twice and getting a head and a tails?
Answer:
Probability for flipping a coin twice and getting heads: 1/2
Probability for flipping a coin twice and getting tails: 1/2
Probability for getting heads AND tails: 0
Probability for getting heads or tails: 1/2
Step-by-step explanation:
Probability is how likely something happens. Since there is only 2 options, the probability for getting one of them would be 1/2 and getting both of them 0, because you can only get one of them. Probability for getting heads or tails would be the same. I'm not sure what your question was, so I did all possible answers. Hope this helps!

Answer:
h(x) = 10 [tex](0.4)^{x}[/tex]
Step-by-step explanation:
The exponential is of the form
h(x) = a [tex](b)^{x}[/tex]
Use the ordered pairs from the table to find a and b
Using (0, 10 ), then
10 = a [tex]b^{0}[/tex] ( [tex]b^{0}[/tex] - 1 ), thus
a = 10
h(x) = 10 [tex]b^{x}[/tex]
Using (1, 4 ), then

b = [tex]\frac{4}{10}[/tex] = 0.4
h(x) = 10 [tex](0.4)^{x}[/tex]

how many x intercepts are in y = x 2+ 4x + 5
Answer:
0 x-intercepts
Step-by-step explanation:
In order to find the x-intercepts ,you need to solve this equation
x² + 4x + 5 = 0 for x and see how many solutions you get:
x² + 4x + 5 = 0
∆ = 4² - 4×1×5 = 16 - 20 = -4
since ∆ < 0 Then the equation has no solution then our Function has none x-intercepts.
check the graph of the function f(x) = x² + 4x + 5 (below)

Jake used 1 centimeter cubes to build a right rectangular prism that has a volume of 24 cubic centimeters. which prism could represent the prism that jake built? please answer fast
Answer:
Shape B (The 2 by 12 one)
Step-by-step explanation:
Because the volume of shape B is 24 and the volume of shape A is 18.
The prism that could represent the prism that jake built is prism B.
What is a prism?A prism is a polyhedron comprising an n-sided polygon base, a second base which is a translated copy of the first, and n other faces, necessarily all parallelograms, joining corresponding sides of the two bases.
The volume of the prism = 24 cubic centimetres.
The volume of a cube = 1 cube centimetre
This means a total of 24 cubes would have been used to make a prism of 24 cubic centimetres volume.
So, the prism that jake built is prism B i.e. 2*18 type prism.
Hence, the prism that could represent the prism that jake built is prism B.

Find the equation of the linear function represented by the table below in slope-intercept form.
Answer:
y = - 3x - 4
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (1, - 7) and (x₂, y₂ ) = (2, - 10) ← 2 ordered pairs from the table
m = [tex]\frac{-10+7}{2-1}[/tex] = - 3 , thus
y = - 3x + c ← is the partial equation
To find c substitute any ordered pair into the partial equation
Using (2, - 10) , then
- 10 = - 6 + c ⇒ c = - 10 + 6 = - 4
y = - 3x - 4 ← equation of linear function

The first four iterates of the function f(x) are 23, 163, 1143 and 8003
The function is given as:
[tex]f(x) = 7x + 2[/tex]
Where:
[tex]x_o=3[/tex]
Substitute 3 for x in f(x)
[tex]f(3) = 7 \times 3 + 2[/tex]
[tex]f(3) = 23[/tex]
Substitute 23 for x in f(x), for the next iteration
[tex]f(23) = 7 \times 23 + 2[/tex]
[tex]f(23) = 163[/tex]
Substitute 163 for x in f(x), for the next iteration
[tex]f(163) = 7 \times 163 + 2[/tex]
[tex]f(163) = 1143[/tex]
Substitute 1143 for x in f(x), for the next iteration

A hamburger patty has approximately
Choose...
grams of protein per ounce.
The fish has approximately
Choose...
grams of protein per ounce.
Answer:
Hamburger patty is 5.67 per ounce and the fish is 5.33 per ounce
Step-by-step explanation:
The hamburger patty has approximately 5.7 grams of protein per ounce and the fish has approximately 5.3 grams of protein per ounce.
What is a fraction?Fraction number consists of two parts one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.
We have:
[tex]4\frac{1}{2}[/tex] ounce hamburger patty has [tex]25\frac{1}{2}[/tex] grams of protein
[tex]4\frac{1}{2}[/tex] = 9/2
[tex]25\frac{1}{2}[/tex] = 51/2
Let's suppose each hamburger patty has x grams of protein so the value of x:
[tex]\rm x = \frac{\frac{51}{2}}{\frac{9}{2} }[/tex]
x = (51/2)×(2/9)
x = 5.66 ≈ 5.7 grams of protein
For fish Let's suppose each fish has y grams of protein so the value of y:
[tex]\rm y =\frac{32}{6}[/tex]
y = 5.3 grams of protein
Thus, the hamburger patty has approximately 5.7 grams of protein per ounce and the fish has approximately 5.3 grams of protein per ounce.
