Determine whether the lines l1 and l2 are parallel perpendicular or neither
Answers
The lines l1 and l2 are perpendicular to each other. They form a 270° angle which means they form three right angles. Hence they are indeed perpendicular due to the fact they intersect at a point if one line is extended by 180°.
Explanation:In this case, we are asked to determine if the lines l1 and l2 are parallel, perpendicular or neither. One critical information presented is that the two lines are perpendicular and form a 270° angle between each other.
Typically, when two lines are perpendicular, they form a right angle, which is 90°. However, a 270° angle suggests they make three right angles, meaning they do not directly intersect at a right angle, but do meet at a point if you extend one line 180° further. Hence, they are indeed perpendicular.
So, although it might seem a bit unusual, based on this information, the lines l1 and l2 are perpendicular to each other.

Please help me with these !!! ❤️❤️ I need it thank youuu!

- Two supplementary angles add up to 180°, forming a straight angle (the angle formed by a straight line)
- The interior angles of a triangle add up to 180°
Given those, we notice that the one unlabeled angle in the figure shares a line with 156°. In fact, this angle is supplementary to 156°, which means that the two add up to 180°. To find the measure of this mystery angle, we can subtract 156 from 180 to obtain 180 - 156 = 24°.
Now, let's look at the triangle. We already know the measure of one of the angles is 24°, and the other two are x°. What else do we know about the angles of a triangle? From the two facts listed at the beginning, we know their interior angles add up to 180°, so let's use that fact to solve for x.
We have:
[tex]x+x+24=180[/tex], or [tex]2x+24=180[/tex]
Solving for x:
[tex](2x+24)-24=180-24\\2x=156\\(2x)/2=(156)/2\\x=78[/tex]
So, x = 78°.

1 nanosecond = one ___
of a __
Answers
1 nanosecond = one billionth of a second
In other words, it takes 1 billion nanoseconds to elapse for one whole second to pass by. It's a very small amount of time.
Answer:
1 nanosecond = 1 billionth of a second
Step-by-step explanation:
A nanosecond (ns) is an SI unit of time equal to one billionth of a second, that is, 1⁄1 000 000 000 of a second, or 10^−9 seconds. The term combines the prefix nano- with the basic unit for one-sixtieth of a minute. A nanosecond is equal to 1000 picoseconds or 1⁄1000 microsecond.

Patrick is making 8 pizzas. he has 15 2/3 cups of mozzarella cheese that he wants to divide evenly among the pizzas.
how many cups of cheese should he put on the pizzas?
Answers
47/3 and divide it by 8 but you have to convert the division in to multiplication and use the reciprocal of 8 which would be 8 = its reciprocal 1/8. We are now left with 47/3 x 1/8 = 47/24; take 47/24 and simplify by taking 47 divided by 24 and we would have 1 23/24 cups per pizza.
Write the expression in algebraic form. [hint: sketch a right triangle.] tan(arcsec(x/3))
Answers
Sketch a right triangle having adjacent side(A) is given as “3”, hypotenuse side (H) is “x” and assigning angle “a” as the angle between A and H. Using Pythagorean theorem, you will get “square root of x-squared minus 9” as the opposite side (O). Using SOH CAH TOA function, and since secant is the reciprocal of cosine, sec(a) = x/3. Thus, a = arcsec(x/3). The remaining expression tan(a) is Opposite side over Adjacent side which is equal to “square root of x^2 - 9” over "3". Therefore, the algebraic expression would be: tan(arcsec(x/3)) = “sqrt (x^2 -9)” /3. Different answers can be made depending on which side you consider the “3” and “x”.

Find the points on the curve given below, where the tangent is horizontal. (round the answers to three decimal places.) y = 7 x 3 + 6 x 2 - 8 x + 7
Answers
To find the points where the tangent is horizontal on the given curve, find the values of x for which the derivative is zero.
Explanation:To find the points on the given curve where the tangent is horizontal, we need to find the values of x for which the derivative of the curve is equal to zero. This is because the derivative represents the slope of the tangent line. Setting the derivative equal to zero and solving for x will give us the x-coordinates of the points.
The given curve is y = 7x³ + 6x² - 8x + 7. To find the derivative of this curve, we use the power rule of differentiation. The derivative is dy/dx = 21x^2 + 12x - 8.
Setting dy/dx equal to zero, we have 21x² + 12x - 8 = 0. To solve this quadratic equation, we can use the quadratic formula: x = (-b ± √(b² - 4ac)) / (2a). Using this formula, we can find the values of x that make the derivative equal to zero.

A firework exploded 1,360 meters away and the sound of the firework took 4 seconds to reach you. At what speed did the sound travel?
Answers
Answer:
Speed of sound, v = 340 m/s
Step-by-step explanation:
It is given that,
A exploded 1360 meters away, d = 1360 meters
time taken, t = 4 seconds
We need to find the speed of the travelled sound. Speed of sound is equal to the distance covered divided by total time taken i.e.
[tex]v=\dfrac{d}{t}[/tex]
[tex]v=\dfrac{1360\ m}{4\ s}[/tex]
v = 340 m/s
So, the speed with which sound is travelled is 340 m/s. Hence, this is the required solution.

f(2) = 9.
Step-by-step explanation:
Given : f(x) = 2x² – 3x + 7.
To find : What is the value of the function when x = 2.
Solution : We have given that f(x) = 2x² – 3x + 7.
For, x = 2
f(2) = 2(2)² – 3(2) + 7.
f(2) = 2 *4 -6 +7
f(2) = 8 - 6 +7.
f(2) = 2 +7
f(2) = 9.
Therefore, f(2) = 9.

Answers
To find the value of y for the point (-1, y) in the equation y = 3x + 4, plug in -1 for x and solve: y = -3 + 4, which simplifies to y = 1. Thus, the value of y is 1.
The student needs to determine the value of y when x is -1 for the equation y = 3x + 4. To find y, we substitute -1 in place of x and solve the equation:
y = 3(-1) + 4
y = -3 + 4
y = 1
Therefore, the value of y for the point (-1, y) is 1.

Tanya planted seedlings in her garden over the weekend. The instructions that came with the seedlings stated that they need to be planted 0.2 meters apart. Tanya has a measuring tape that has values in centimeters. Help Tanya convert meters to centimeters.
Answers
Answer:
20 centimeters apart.
Step-by-step explanation:
Tanya planted seedlings in her garden over the weekend.
The instructions that came with the seedlings stated that they need to be planted 0.2 meters apart.
Tanya has a measuring tape that has values in centimeters.
As we know 1 meter = 100 centimeters
therefore, 0.2 meter = 0.2 × 100 = 20 centimeters
So Tanya need to be planted 20 centimeters apart.
the scale of a map is 1 cm :50 mi. Determine the distance between two cities that are
4.2 cm apart on the map
Answers
The actual distance between two cities that are 4.2 cm apart on a map with a scale of 1 cm : 50 mi is 210 miles. The distance was calculated using a direct proportion based on the map's scale.
Explanation:To determine the actual distance between two cities that are 4.2 cm apart on a map with a scale of 1 cm : 50 mi, you can use the following method:
First, understand that the scale means for every 1 cm on the map, the actual distance is 50 miles. Therefore, you can set up a direct proportion to solve for the actual distance.
Scale of map: 1 cm : 50 mi
Distance on map: 4.2 cm
Setting up the proportion, we get:
1 cm / 50 mi = 4.2 cm / x miNow, solve for 'x' which represents the actual distance between the two cities.
x = (4.2 cm × 50 mi) / 1 cmx = 210 miThe actual distance between the two cities is 210 miles.
