Answer:

a>12.5.

Step-by-step explanation:

you need to look at the discriminant in the quadratic formula:

[tex]b^{2} -4ac[/tex]

coming from the quadratic polynomial

[tex]ax^{2} +bx+c=0[/tex]

In our case, b=10 and c=2, hence, the discriminant is

[tex]10^2-4*a*2 \\100-8a[/tex]

We will obtain non-real values if the discriminant is less than zero.

Therefore, this condition is written as

[tex]100-8a<0[/tex]

and we must solve for a. It yields

[tex]100<8a\\a>\frac{100}{8} \\a>12.5[/tex]

Hence, the answer is a>12.5.

The values of a that will result in this equation having non-real solutions must e greater than 12.5

Given the quadratic equation  ax^2 + 10x + 2 = 0

For the equation to have non-real solutions, then b^2 - 4ac < 0

From the given equation;

a = a

b = 10

c = 2

Substitute the given parameters into the formula;

10^2 - 4a(2) < 0

100 - 8a < 0

-8a < -100

8a > 100

a > 12.5

Hence the values of a that will result in this equation having non-real solutions must e greater than 12.5

D BOTTOM RIGHT

Step-by-step explanation:

Answer:

see explanation

Step-by-step explanation:

Given 2 sides of a triangle then the third side x is between the limits

difference of 2 sides < x < sum of 2 sides, that is

7 - 5 < x < 7 + 5 , then

2 < x < 12

Choose any 2 values between 2 and 12 as third side, so

third side could be 6 or 9 for example

Answer:

y = 12 [tex](2.9)^{x}[/tex]

Step-by-step explanation:

The standard form of the exponential function is

y = a [tex](b)^{x}[/tex]

Find a and b by substituting ordered pairs from the table into the equation

Using (0, 12 ), then

12 = a[tex]b^{0}[/tex] ( [tex]b^{0}[/tex] = 1 ), so

a = 12, then

y = 12 [tex]b^{x}[/tex]

Using (1, 34.8 ) , then

34.8 = 12 [tex]b^{1}[/tex] ( divide both sides by 12 )

b = 2.9

Thus exponential function is

y = 12 [tex](2.9)^{x}[/tex]

Answer:

16

Step-by-step explanation:

Given

u = x₁i + y₁j and v = x₂i + y₂j , then

u • v = x₁x₂ + y₁y₂

Given

u = - 4i + 8j and v = - 2i + j , then

u • v = ( - 4 × - 2) + (8 × 1) = 8 + 8 = 16

Answer:

C

Step-by-step explanation:

Answer:

1). x = 14

2). y = 2.4 cm

Step-by-step explanation:

In the diagram ΔNPQ ~ ΔNLM and NL = 3,

1). ∠P ≅ ∠L [All angles of similar triangle are equal in measure]

   (3x + 18)° = 60°

   3x = 60 - 18

   x = 14

2). Since, both the triangles are similar, corresponding sides will be proportional.

   [tex]\frac{PN}{NL}=\frac{NQ}{NM}[/tex]

   [tex]\frac{y}{3}=\frac{3.2}{4}[/tex]

   y [tex]=\frac{3.2\times 3}{4}[/tex]

   y = 2.4 cm

Answer:

<6, <4,

Step-by-step explanation:

Remote interior angles are interior angles of a triangle where they do not share a point with the exterior angle. So for <6, it's remote interior angles are <1 and <2, and for <4, it's remote interior angles are <3 and <2.

Answer:

x = 1/5, y = 6

Step-by-step explanation:

5x + y = 7

y = 7 - 5x

Set equations equal to each other to eliminate y

7 - 5x = 20x + 2

7 = 25x + 2

5 = 25x

x = 1/5

y = 7 - 5(1/5)

y = 7 - 1

y = 6

Answer:

$766.28

Step-by-step explanation:

The equation for interest rate is as follows:

[tex]A = P(1 + r)^t\\[/tex]

A = The total amount

P = Initial amount

R = The interest rate

T = Time

Let's plug everything into the equation that is given in the question:

The initial amount = 612

Interest rate = 2.85

Time = 8 years

[tex]A = 612(1+.0285)^8[/tex]

***Just a reminder we move the decimal over twice when working with percents***

Now, lets solve for the total amount:

[tex]A = 612(1.0285)^8\\A = 612(1.252086602)\\A = 766.28[/tex]

Therefore, after 8 years the principal is $766.28.
