if a quadratic equation with real coefficients has a discriminant of -36 then what type of roots does it have

Aleks04 [339]

Step-by-step explanation:

We have,

If a quadratic equation with real coefficients has a discriminant of -36.

The general form of quadratic equation is :

$ax^2+bx+c=0$

The discriminant of this equation is : $D=b^2-4ac$

If D=0, it will have 1 real roots

If D>0, it will have 2 real roots

If D<0, it will have no real roots

We have,

D = -36 < 0, so, the quadratic equation will have no real roots.

Lexie began making posters for the school awards banquet. She can make 6 posters per minute. Zach joined her 10 minutes after sh

Snowcat [4.5K]

10 * 6 = 60 by the time Zach joins so 125-60 = 65
Now 6 (lexie) +7 (zach) = 13 (together) and 65/13 = 5.
6*5 = 30 and 7*5 = 35. 35+30 = 65
Your answer is 5.

The length of a text messaging conversation is normally distributed with a mean of 2 minutes and a standard deviation of .5 minu

Phoenix [80]

Let x be a random variable representing the length of a text messaging conversation, then
P(x > 3) = 1 - P(x < 3) = 1 - P(z < (3 - 2)/0.5) = 1 - P(z < 2) = 1 - 0.97725 = 0.02275

Magaldi is constructing its cash budget. Its budgeted monthly sales are $20,000, and they are constant from month to month. 60%

iogann1982 [59]

Answer:

$5,820

Step-by-step explanation:

The average net cash flow during the month is total cash receipt minus total payments.

Cash receipt on the month's sales=60%*$20,000*98.5%=$11820

60% cash received ,the 98.5% is after cash discount of 1.5%

cash receipt from previous month sale=40%*$20,000=$8,000

Payment for purchases=$20,000*40%=$8,000

payment for wages,rent and taxes=$20,000*30%=$6000

Total cash inflow=$11,820+$8,000=$19820

total cash outflow=$8,000+$6,000=$14,000

average net cash flow=$19,820-$14,000=$5,820

A = 8: b = ; C = 10.

lara [203]

Answer:

b=6

$a^{2} + b^{2} = c^{2} \\ {8}^{2} + {b}^{2} = {10}^{2} \\ 64 + {b}^{2} = 100 \\ 100 - 64 = {b}^{2} \\ 36 = {b}^{2} \\ \sqrt{36} = \sqrt{ {b}^{2} } \\ 6 = b$
