If the discriminant of an equation is positive, which of the following is true of the equation
A it has one complex solution
B it has one real solution
C it had two real solutions
D it has two complex solutions

Answers

Answer:

C it has two real solutions

Step-by-step explanation:

If the discriminant of a quadratic equation is positive, it means that the graph intersects the x-axis, and hence produces two real solutions.

If the discriminant is zero, then the graph is tangential to the x-axis, and there will be two real coincident solutions.

If the discriminant is negative, then there are two complex solutions.

Answers

Answer:

A scale factor exists because any two circles are similar. You can use the radii to determine the scale factor.

Step-by-step explanation:

The ratio between the radii is 31 so the scale factor is 31=3. The circumference of the smaller circle is C=2π(1)=2π.

We have the equation 1/2x + 200 =1200 so we know that we have 200 already as one of the numbers so 1/2 is half of x + 200 equals 1200 since we have 200 we know that 1/2 of x is going to be 1000 because 1000+200=1200 meaning x is 2000. So your answer would be x=2000 or 1/2 2000 + 200=1200

On a given planet, the weight of an object varies directly with the mass of the object. Suppose that an object whose mass is 9kg weighs 63 N . Find the weight of an object whose mass is 5kg.

Answers

Answer:

Step-by-step explanation:

9Kg =63N

5Kg=X (Cross Multiple)

=X×9 =5×63

divide both sides by 9

X=5×63

---------

=35

Answer:

35 N

Step-by-step explanation:

let w = weight of object

and m = mass of object

w = mk where k is the constant of proportion

63 = 9k

k = 7

So, w = 7m

w = 7(5) = 35 N

Trey bought 3 and 3 fourths pounds of apples from the grocery store. Corinne bought 1 and 1 third pounds of grapes from the grocery store. How many more pounds of fruit did Trey buy

Answers

Answer: 2 5/12

Step-by-step explanation:

Trey bought 3¾ pounds of apples from the grocery store. Corinne bought 1⅓ pounds of grapes from the grocery store.

To know how many more pounds of fruit that Trey bought, we have to find the difference between the value given above and this will be:

= 3¾ - 1⅓

= 3 9/12 - 1 4/12

= 2 5/12

Trey bought 2 5/12 pounds more.

Part A: Mike wants to join a gym. He has to pay an initiation fee of $16 and equal monthly payments for the year. The most he wants to pay is $580 for the year for his gym membership. a.) Write an inequality that you can use to determine the most he would want to spend for his monthly payments.

Part B: Now use your inequality from 15a to determine how much Mike’s monthly gym payment can be if the most he wants to pay is $580 for the year for his gym membership..

Answers

Answer:

Part A: [tex]12x+16\leq 580[/tex]

Part B: $47 per month

Step-by-step explanation:

Part A: 12 months in a year. Pays x amount of $ per year, with an additional $16 initiation fee. He wants to spend less than $580 total a year. Thus, [tex]12x+16\leq 580[/tex].

Part B: Solve the inequality for x.

$580 - $16 = $564

x = $564/12 = $47

The interior angles of a parallelogram will always equal 360. The interior angles of a triangle are 180 if it is a equilateral triangle then the angles are 60 degrees each. You know 2 sides of parallelogram. The 100 degree and 90 degree. You can find the one opposing the x because it’s on a straight line and a straight line is 180 degrees if a triangle is 60 degree angle then the opposing angle to complete the straight line must be 180-60 so you get 120. You now know 3 sides. 120, 90 and 100
They should add up to be 360 so you can set up an equation like so
120+90+100+x=360
And x = 50

Answer:

x = 50°

Step-by-step explanation:

The triangle has 3 congruent sides and is therefore equilateral.

The 3 angles are then congruent, each 60°

The left angle in the quadrilateral is adjacent to 60° of the triangle

180° - 60° = 120° ← angle inside quadrilateral

The sum of the interior angles of a quadrilateral = 360°

Subtract the sum of the angles from 360° for x

x = 360° - (120 + 90 + 100)° = 360° - 310° = 50°

Andrea uses 9.8 pints of white paint and blue paint to paint her bedroom walls. 1 4 of this amount is white paint, and the rest is blue paint. How many pints of blue paint did she use to paint her bedroom walls?

Answers

Answer:

7.35

Step-by-step explanation:

Andrea uses 9.8 pints of white and blue paints to paint her bedroom walls

1/4 of this amount is white paint

= 1/4 × 9.8

= 0.25×9.8

= 2.45

Therefore the amount of blue paint can be calculated as follows

9.8-2.45

= 7.35

Hence 7.35 are blue paint

Solve with ratio sin(30) to solve the missing side length x. Round to the nearest tenth

Answers

Answer: x=5

Explanation:
sin=opposite side/hypotenuse
The opposite side is x and the hypotenuse is 10.
So your equation is: sin(30)=x/10
In order to get x by it self times ten to each side of the equation.
10 x sin(30)= x
Put 10 x sin(30) into graphing calculator and make sure your calculator is set to degrees.
Your answer:
5= x

Work on paper:

Answer:

we have

sin30=perpendicular/hypotenuse

1/2=x/10

x=½×10=5

x=5
