what is the answer to w²-15w =0 ​

Answers

Answer 1

Answer:

w = (0, 15)

Step-by-step explanation:

w²-15w =0

w(w-15)=0

w=0 , w=15

if w=0

0(0-15)=0

0(-15)=0

0=0

if w=15

15(15-15)=0

15(0)=0

0=0

Phil left an estate valued at 140,000. In His will, he specified that his wife will get 25% more of his estate than his daughter. How much will his wife recieve?

Answers

Answer:

77,777.78

Step-by-step explanation:

The computation of the amount that would be received by his wife is shown below:

Let us assume the daughter would received x

So his wife would received 1.25x

The total estate value is 140,000

Now the equations would be

140,000 = x + 1.25x

140,000 = 2.25x

x = 62,222.22

So his wife would received

= 62,222.22 × 1.25

= 77,777.78

What is the distance between (4, 7) and (-8, 3)? Round to the nearest tenth.

Answers

Answer:

The distance is approximately 12.6.

Step-by-step explanation:

Moving from (-8, 3) to (4, 7), we see x (the horizontal dimension) increasing by 12 and y (the vertical dimension) increasing by 4.  Think of 12 and 4 as the legs of a right triangle whose hypotenuse represents the distance between these two given points.

This distance, from the Pythagorean Theorem, is

d = √(12^2 + 4^2) = √(144 + 16) = √160 = √16√10.

The desired distance is approximately 12.6.

Solving an inequality is a lot like solving an equation, one uses inverse operations. The major difference between solving an inequality and an equation is that when one multiplies or divides by a negative number, then one must remember to flip the inequality sign, such a rule doesn't come into play in this case.

Determina la EPG que adquiere una trapesista de 52 kg de masa cuando sube a un trapecio de 8 metros de altura. Considera g=9.81

Answers

Responder:

4080,96 Julios

Explicación paso a paso:

La energía potencial gravitacional adquirida se puede obtener mediante la relación:

EPG = masa * aceleración por gravedad * altura

Masa = 52 kgb; aceleración debida a la gravedad = 9,81; h = 8 metros

EPG = 52 * 9,81 * 8

EPG = 4080,96 julios

Anyway use this method.

Use the vertical line test to determine whether or not a graph represents a function. If a vertical line is moved across the graph and, at any time, touches the graph at only one point, then the graph is a function. If the vertical line touches the graph at more than one point, then the graph is not a function.

algebraically find the x-coordinates where the line y=2x+3 intersects the circle (x-3)^2 + (y+6)= 50
** please help its due soon **

Answers

Answer:

x = {-4, -2}

Step-by-step explanation:

To find the intersection we need to solve the system:

y = 2x + 3(x - 3)² + (y + 6)² = 50

Solve by substitution, replace y with 2x + 3 in the second equation:

(x - 3)² + (2x + 3 + 6)² = 50x² - 6x + 9 + 4x² + 36x + 81 - 50 = 05x² + 30x + 40 = 0x² + 6x + 8 = 0x² + 6x + 9 = 1(x + 3)² = 1x + 3 = ± 1x = -4, x = -2

Write a cubic function whose graph goes through the points: (-5, 0) (1, 0) (2, -2) (4, 0)

Answers

Answer:

f(x) = [tex]\frac{1}{7}(x+5)(x-1)(x-4)[/tex]

Step-by-step explanation:

Let the equation of the give cubic function is,

f(x) = p(x - a)(x - b)(x - c)

Here, a, b, c and d are the x-intercepts of the given graph.

Since, x-intercepts given in the graph are x = -5, 1 and 4,

Equation of the curve will be,

f(x) = p(x + 5)(x - 1)(x - 4)

Since, the graph of this function passes through (2, -2) also

-2 = p(2 + 5)(2 - 1)(2 - 4)

-2 = -p(14)

p = [tex]\frac{2}{14}[/tex]

p = [tex]\frac{1}{7}[/tex]

Therefore, equation will be,

f(x) = [tex]\frac{1}{7}(x+5)(x-1)(x-4)[/tex]

Answer:

Angle ADC = 80 degrees

Step-by-step explanation:

Here, we want to find the measure of angle ADC

mathematically, sum of angles at a point is 360

Thus;

x + 3x + x + 10 = 360

5x + 10 = 360

5x = 360-10

5x = 350

x = 350/5

x = 70

From the diagram;

angle ADC is (x + 10)

so we have; (70 + 10) = 80 degrees

The ratio of green bags to white bags in the store is equal to 2 to 5.There are 30 white bags in the store how many green bags are there?

Answers

Answer:

12 green bags

Step-by-step explanation:

Given data

The given ratio of green bags to white bags is

=2 to 5

=2:5

Number of white bags=30

Applying the part to part method, let the number of green bags be x

so

2/5=x/30

cross multiply

30*2=5x

60=5x

divide both sides by 5

x= 60/5

x=12

Hence there are 12 green bags
