What is the value of x?

Answer:

m = -1/2

Step-by-step explanation:

4 − 2 = 12

= −2 = 12 − 4

= = (12 − 4) ÷ (−2)

= = 2−6

So, the slope is 2.

Now, keep this rule in mind: the product of a slope of two perpendicular lines will be -1.

Thus, the slope of the line that is perpendicular to this line is -1/2

Explanation:

For now, let's ignore the blue curve.

If we kept the red curve completely fixed in place, and only moved the xy axis, then we can move the xy axis 5 units to the right to give the illusion the red curve is moving (even though it's fixed in place).

Moving the xy axis 5 units to the right means each x input is 5 units larger. So x jumps up to x+5

In other words, going from f(x) to f(x+5) will shift the f(x) curve 5 units to the left. So that's why we go from x^2 to (x+5)^2 which is what choice D shows.

Se debe remover aproximadamente 140.848 centímetros cúbicos de madera para reducir las esferas a anillos con altura de 6 centímetros.

En esta cuestión se precisa calcular el volumen de la esfera y sustraer los volúmenes de dos casquetes esféricos de igual cantidad [1] y un cilindro recto respectivo a la operación de taladrado. [2] La cantidad de madera a remover queda definida por la siguiente expresión:

[tex]V = \frac{2\pi}{3}\cdot h^{2}\cdot (3\cdot R - h) + \pi\cdot r^{2}\cdot (2\cdot R-2\cdot h)[/tex] (1)

Donde:

Si sabemos que [tex]h = 1\,cm[/tex], [tex]R = 4\,cm[/tex] y [tex]r = 2.5\,cm[/tex], entonces la cantidad de madera a remover es:

[tex]V = \frac{2\pi}{3}\cdot (1\,cm)^{2}\cdot [3\cdot (4 \,cm) - 1\,cm] +\pi\cdot (2.5\,cm)^{2}\cdot [2\cdot (4\,cm)-2\cdot (1\,cm)][/tex]

[tex]V \approx 140.848\,cm^{3}[/tex]

Answer:

This given triangle is an equilateral triangle.

The length of AC in the given triangle ABC as per the given condition is equal to 4 units.

To find the length of side AC (opposite angle BAC and BCA) in triangle ABC,

Use the triangle's angle-side-angle (ASA) property.

Side length of AB = x + 4,

Side length of BC = 3x - 8,

Side length of AC = x,

and m∠BAC = m∠BCA.

First, let's write down the ASA property:

If in two triangles, two angles and the included side of one triangle are equal to two angles and the included side of the other triangle,

Then the two triangles are congruent.

Here, angle BAC and angle BCA are equal, and their included side AC is common to both triangles.

So, set up the equation,

x + 4 = 3x - 8

Now, solve for x:

This implies,

⇒3x - x = 4 + 8

⇒ 2x  = 12

Divide both the side by 2 we get,

⇒ 2x / 2 = 12/2

⇒ x = 6

Now that found the value of x, find the length of AC:

AC = x = 4

Therefore, the length of AC is 4 units.

Answer:

the answer is 8 oz

Step-by-step explanation:

well it says for the first ounce is $0.49 so $0.49 is your first number, then you're trying to figure out how many $.21

2.then to make this easier you subtract $0.49 from $1.96 and that's is $1.47

3.then all you need to do is divide $1.47 By .21 cents anand you should get 7.

4.but don't forget the $0.49 for the first ounce, then 1 ounce add it to the 7 and It will equal 8 oz in total

I don't really know how to explain step-by-step from my messy notes

The overall percentage increase of the cost of gasoline during the three-year period is 14.33%.

A percentage is a number or ratio expressed as a fraction of 100. It is generally denoted using the percent sign ''%''.

The given percentage are,

8%, 15%, and 20%.

Now to find the overall average increase we need to find the average percentage for three consecutive years.

overall average = sum of all the percentage/number of percentage

overall average =  8%+15%+ 20%/3

overall average =  43%/3

overall average =  14.33%

Hence,The overall percentage increase of the cost of gasoline during the three-year period is 14.33%.

Answer:

using phythagoras formula of right angles we can calculate the hypotenuse

1^2=x^2+17^2

x^2=17^2-1^2(transpose)

×^2=288 (introduce a square root)

x=15.01(round of to the nearest tenth)

Step-by-step explanation:

x=10

The measure of the hypotenuse is 17.029

If ABC is a triangle with AC as the hypotenuse and angle B with 90 degrees then we have Pythagoras theorem:

|AC|^2 = |AB|^2 + |BC|^2    

where |AB| = length of line segment AB. (AB and BC are rest of the two sides of that triangle ABC, AC being the hypotenuse).

Given;

The legs of a right triangle measures 1 cm

The other leg measures 17 cm

Now,

|AC|^2 = |AB|^2 + |BC|^2    

|AC|^2 = |1|^2 + |17|^2    

|AC|^2 = 1 + 289

AC=17.029

Therefore, by pythagoras theorem answer will be 17.029.

Hi! I'm happy to help!

Our town is composed of 2,000 people. Of those 2,000 people, 4/5 of them are middle class. The word 'of' usually means multiplication when it is in a word problem. So, we will multiply 2,000 by 4/5. When multiplying a whole number, we just multiply it by the numerator (top) and leave the denominator. (bottom)

2,000×4

8,000

8,000/5

Fractions are just a different way of putting division, so we can change this to a division problem:

8,000÷5=

1,600
