First triangle is a 45-45-90 triangle. In most basic form, the two equal sides have length 1 and the hypotenuse has length √2. Do not write x√2.
Second triangle: The shortest side is 1, the longer side is √3 and the hypotenuse is 2. You could verify this using the Pythagorean Theorem:
2² = 1² + (√3)² is true.

If f(x) = |x – 5| + 3, find f(2).
Answer:
f(2)=6
Step-by-step explanation:
f(x) = |x – 5| + 3 and find f(2). We plug in 2 for x
f(2) = |2 – 5| + 3
f(2) = |-3| + 3 absolute value makes the number inside positive
f(2)= 3+3
f(2)= 6
Factor the expression 3x-12
Answer:
3(x-4)
Step-by-step explanation:
Answer: 3(x-4)
Step-by-step explanation:
Hii! Do you need to factor the expression 3x-12? No problem! (:
Note that both terms have something in common; it's known as the greatest common factor, or g.c.f.
The g.c.f. of 3x and -12 is 3, so we divide both 3x and -12 by 3.
We obtain
x-4
Now we put parentheses around x-4.
(x-4)
Next, we put 3 (the number we factored out) outside these parentheses.
3(x-4)
Voila! There's our answer, cheers!

a right trangle has one angle that measures 70 what is the measure of the other acute angle in the triangle
Answer:
20
Step-by-step explanation:
We know that the interior angle measures of a triangle are 180, and we are told that this is a right triangle.
Since we know the measure of two angles, we just have to do basic math:
180=90+70+x
solve for x (which equals 20) to get the measure of your acute angle
Final answer:
In a right triangle with one acute angle measuring 70 degrees, the measure of the other acute angle is 20 degrees, as the sum of all angles in a triangle is 180 degrees.
Explanation:
The sum of the angles in any triangle is always 180 degrees. In a right triangle, one of the angles is always 90 degrees, which is the angle that makes it "right." If a right triangle has one acute angle that measures 70 degrees, to find the measure of the other acute angle, we subtract the known angles from 180 degrees:
180 degrees (total in a triangle) - 90 degrees (right angle) - 70 degrees (given acute angle) = 20 degrees.
Therefore, the measure of the other acute angle in the triangle is 20 degrees.

A^2 + b^2 = c^2
C is your hypotenuse or the longest side of the triangle; you plug in your values and solve for the missing side:
15^2 + b^2 = 17^2
225 + b^2 = 289
*-225 on both sides to get b by itself*
B^2 = 64
*to get rid of the ^2; you take the square root*
B = sqrt 64
B= 8 <— final answer
We can use the Pythagorean Theorem to solve for the missing side length (a).
Pythagorean Theorem:
a² + b² = c²
a and b are the legs (shorter sides) of the triangle and c is the hypotenuse (the longer side of the triangle).
1. Substitute in the known values.
a = ?
b = 15
c = 17
a² + 15² = 17²
2. Solve for a.
a² + 15² = 17²
a² + 225 = 289
a² + 225 - 225 = 289 - 225
a² = 64
√a² = √64
a = 8

Suppose a football is kicked with an initial velocity of 82 ft/sec., at an angle of
58° to the ground. What is the position of the ball after two seconds?
(Remember: Acceleration due to gravity is 32 ft/s².) Round your answer
to the nearest whole foot. Show all work.
Answer:
The position P is:
[tex]P = 87\^x + 75\^y[/tex] ft Remember that the position is a vector. Observe the attached image
Step-by-step explanation:
The equation that describes the height as a function of time of an object that moves in a parabolic trajectory with an initial velocity [tex]s_0[/tex] is:
[tex]y(t) = y_0 + s_0t -16t ^ 2[/tex]
Where [tex]y_0[/tex] is the initial height = 0 for this case
We know that the initial velocity is:
82 ft/sec at an angle of 58 ° with respect to the ground.
So:
[tex]s_0 = 82sin(58\°)[/tex] ft/sec
[tex]s_0 = 69.54[/tex] ft/sec
Thus
[tex]y(t) = 69.54t -16t ^ 2[/tex]
The height after 2 sec is:
[tex]y(2) = 69.54 (2) -16 (2) ^ 2[/tex]
[tex]y(2) = 75\ ft[/tex]
Then the equation that describes the horizontal position of the ball is
[tex]X(t) = X_0 + s_0t[/tex]
Where
[tex]X_ 0 = 0[/tex] for this case
[tex]s_0 = 82cos(58\°)[/tex] ft / sec
[tex]s_0 = 43.45[/tex] ft/sec
So
[tex]X(t) = 43.45t[/tex]
After 2 seconds the horizontal distance reached by the ball is:
[tex]X (2) = 43.45(2)\\\\X (2) = 87\ ft[/tex]
Finally the vector position P is:
[tex]P = 87\^x + 75\^y[/tex] ft

What value of y makes
the equation below true?
y + 2.9 = 11
A 8.1
B 8.9
C 9.1
D 13.9
Answer is “A”
Because since we know if we need to find the y is so we need to subtract 11-2.9=8.1
which mean y mean 8.1
The answer would be A
That is because you can not add unlike terms, so you would have to subtract 2.9 - 11 to find your answer. Therefore, the answer is 8.1

If the equation y = 1 5 x + 2 is changed to y = 1 5 x - 4, how will the graph of the line change? A) It will shift down 4 units. B) It will shift down 6 units. C) It will shift right 4 units. D) It will shift right 6 units.
Answer:
It will shift down 6 units.
ANSWER
B) It will shift down 6 units.
EXPLANATION
The given function is
y=15x+2
We want to find how the graph of this function will change if the function is transformed to
y=15x-4
We rewrite this function in terms of the first one to get:
y=15x+2+-6
Hence the function with shift down 6 units.
In the graph, z is a complex number represented as a vector from the origin. What is the product of z and its conjugate?
Answer:
5
Step-by-step explanation:
Given a complex number x + yi then the conjugate is x - yi
Note the real part remains unchanged while the sign of the imaginary part is negated.
here z = 1 - 2i hence conjugate is 1 + 2i
and the product is
(1 - 2i)(1 + 2i) ← expand factors
= 1 - 4i² [ i² = - 1 ]
= 1 + 4
= 5
The product of z and its conjugate will be 5.
What is a complex number?The complex number is the combination of the real part and the imaginary part. Then the complex number is given as
⇒ a+bi
In the graph, z is a complex number represented as a vector from the origin.
Then the complex number will be
z = 1 – 2i
Then the conjugate of z will be
⇒ 1 + 2i
Then the product of z and its conjugate will be
⇒ (1 – 2i)(1 + 2i)
⇒ 1² – 2²i²
We know i² = -1
⇒ 1 – 4(-1)
⇒ 1 + 4
⇒ 1² – 2²i²
⇒ 5

John has a deck of cards 52 cards of John remove the number to car from the deck what is the probability that he will pick up a number two card at random ?
Answer:
3 out of 51
Step-by-step explanation:
If he removed one number two card from the deck then there should be three left since there are 4 of each number card in a deck so therefore there should be 51 cards in the deck but only three number two cards left in the deck
The probability of drawing a number two card from a 52-card deck after removing all four number two cards is 0, as there are no such cards left to draw.
Calculating the Probability of Drawing a Number Two Card
If John removes the number two card from a standard 52-card deck, the deck then has 48 cards because there are 4 number two cards, one in each suit (clubs, diamonds, hearts, and spades). Since these cards are no longer in the deck, the probability of picking up a number two card at random from the remaining deck is 0, as there are no number two cards left to draw.
Initially, the probability of drawing a two card from a full deck would be 4 out of 52 cards or 1 out of 13, as there are 4 twos in the set of 52 cards. However, with the removal of all four number twos, there are no such cards left, hence the probability of drawing a two is reduced to 0.
Understanding probability in a deck of cards is a fundamental concept in statistics and probability theory, which can be applied to various practical situations including games and predictive models.

Step-by-step explanation:
An engineer estimated the weight of a steel beam to be 600 pounds. The actual weight of the beam was 639 pounds. Find the absolute error and the percent error of the engineer's estimate. If necessary, round your answers to the nearest tenth.
Answer:
Absolute error = 39
Percent Error = 6.10%
Step-by-step explanation:
Actual value = 639 pounds
Observed Value = 600 pounds
The formula to find absolute error is:
Absolute Error = Actual value - Observed Value
= 639 - 600
= 39
The formula to find Percent error is:
Percent Error = (Actual value - Observed Value / Actual value)*100
= (639 - 600/639)*100
= 6.10%
Answer:
Absolute error = 39 pounds
Percent error = 6.10%
Step-by-step explanation:
We know that the estimated weight was 600 pounds while the actual weight of the beam was 639 pounds.
So we will find their difference to get the absolute error.
Absolute error = 639 - 600 = 39 pounds
We will use the following formula to find the percent error.
Percent error = (Estimated value - actual value / actual value) * 100
Percent error = 639 - 600 / 600 * 100 = 6.10%

in the system shown below, what are the coordinates of the solution that lies in quadrant IV? x2+y2=25 x-y2=-5
Answer:
[tex]x=4,y=-3[/tex], or as an ordered pair: (4, -3)
Step-by-step explanation:
We have the system of equations
[tex]x^2+y^2=25[/tex] (1)
[tex]x-y^2=-5[/tex] (2)
Let's solve our system step-by-step:
Step 1. Solve for [tex]y^2[/tex] in equation (1)
[tex]x^2+y^2=25[/tex]
[tex]y^2=25-x^2[/tex] (3)
Step 2. Replace equation (3) in equation (2) and solve for [tex]x[/tex]
[tex]x-y^2=-5[/tex]
[tex]x-(25-x^2)=-5[/tex]
[tex]x-25+x^2=-5[/tex]
[tex]x^2+x-20=0[/tex]
[tex](x+5)(x-4)=0[/tex]
[tex]x+5=0,x-4=0[/tex]
[tex]x=-5,x=4[/tex]
Remember that in the fourth quadrant x is positive and y is negative, so we are taking the positive value of x; in other words [tex]x=4[/tex] (4)
Step 3. Replace equation (4) (the positive value of x) in equation (1)
[tex]x^2+y^2=25[/tex]
[tex]4^2+y^2=25[/tex]
[tex]16+y^2=25[/tex]
[tex]y^2=25-16[/tex]
[tex]y^2=9[/tex]
[tex]y=\sqrt{9} ,y=-\sqrt{9}[/tex]
[tex]y=3,y=-3[/tex]
Since y is negative in quadrant IV, we take [tex]y=-3[/tex]
We can conclude that the solution of our system of equations that lies in the quadrant IV is [tex]x=4,y=-3[/tex], or as an ordered pair: (4, -3)

If 11 bumper stickers cost $10.34 then 30 bumper stickers cost
Answer:
$28.20
Step-by-step explanation:
Let's set up an equation.
Let b be the cost of a bumper sticker.
Since the sum of the prices of 11 bumper stickers total up to $10.34, we can set up an equation!
11b = 10.34
Dividing by 11 on both sides,
b = 0.94
Plugging in b into 30b,
30(0.94)
We get
$28.20
Answer:
$28.20
Step-by-step explanation:
First, find out how much each bumper sticker costs.
Assuming that the cost of each bumper sticker is the same, the following equation represents how much one bumper sticker costs
11x = 10.34
Solve for x [divide both sides by 11]
x = 0.94
So, one bumper sticker costs $0.94
Now, find out how many 30 bumper sticker costs.
The following equation represents how much 30 stickers cost.
30x = y
X represents the cost of one sticker and y represents the cost of 30 stickers.
We already know the value of x [one bumper sticker's cost] which is $0.94, so subsitute that in for x.
30[0.94] = y
28.2 = y
So, 30 bumper stickers cost $28.20.
