Answer:

114°

Step-by-step explanation:

By property of intersecting chords inside a circle.

\because \angle \: 1 =  \frac{1}{2} (x + y) \\  \\  \therefore \: \angle \: 1 =  \frac{1}{2} (96 + 132)  \\  \\  \therefore \: \angle \: 1 =  \frac{1}{2} \times 228\\  \\   \huge \red { \boxed{\therefore \: \angle \: 1 = 114 \degree}}

In a shipment of 600 parts, 30 are found to be defective. How many defective parts should be expected in a shipment of 1000?
kobusy [5.1K]
We can except 30/600 = 0.05>> 5%percent,
so 1000 * 0.05 = 50 parts defective

AFLATI 2 NUMERE STIIND CA AL DOILEA NUMAR ESTE DE 7 ORI MAI MARE DECITPRIMUL IAR SUMA DINTRE DUBLUL PRIMULUI NUMAR SI TRIPLUL CE
postnew [5]

Answer:

The numbers are 20 and 140

Step-by-step explanation:

<u><em>The question in English is</em></u>

Find 2 numbers knowing that the second number is 7 times greater than the first, and the sum between the double of the first number and the triple of the second is 460

Define the variables

Let

x ----> the first number

y ----> the second number

we know that

y=7x -----> equation A

2x+3y=460 ----> equation B

Solve the system of equations by substitution

Substitute equation A in equation B

2x+3(7x)=460

solve for x

2x+21x=460

23x=460

x=20

<em>Find the value of y</em>

y=7x  ----> y=7(20)=140

The numbers are 20 and 140

<h3>Answer:  choice 4. f(x) and g(x) have a common x-intercept</h3>

===========================================================

Explanation:

For me, it helps to graph everything on the same xy coordinate system. Start with the given graph and plot the points shown in the table. You'll get what you see in the diagram below.

The blue point C in that diagram is on the red parabola. This point is the x intercept as this is where both graphs cross the x axis. Therefore, they have a common x intercept.

------------

Side notes:

  • Choice 1 is not true due to choice 4 being true. We have f(x) = g(x) when x = 2, which is why f(x) > g(x) is not true for all x.
  • Choice 2 is not true. Point B is not on the parabola.
  • Choice 3 is not true. There is only one known intersection point between f(x) and g(x), and that is at the x intercept mentioned above. Of course there may be more intersections, but we don't have enough info to determine this.
