F(x)=-4x^2+10x-8

What is the value of the discrimination of F?

How many distinct real number zeros does f(x) have?

Please and thank you!!

Answer:

d=8c

Step-by-step explanation:

Answer:

x= -1/4

Step-by-step explanation:

2(4x + 5) = 8

8x+10=8

8x=8-10

8x=-2

x=-2/8

x=-1/4

Answer:

it could be .25

Step-by-step explanation:

distribute 2 to 4x +5

8x + 10 = 8

     - 10 - 10

8x = - 2

divide by 8

x = .25 or 1/4

Sam rides his bicycle for 1.6 hours.

Here is the solution:

Time = Distance / Speed

Time = 11.2 km / 7 km/hour

Time = 11200 m / 7000 m/hour

Time = 1.6 hours

Therefore, Sam rides for 1.6 hours.

Answer:

The center is (0, -9) and the radius is 5

Step-by-step explanation:

The equation of a circle can be written as

(x-h)^2 + (y-k)^2 = r^2  where (h,k) is the center and r is the radius

x^2 + (y + 9)^2 = 25

(x-0)^2 + (y- -9)^2 = 5^2

The center is (0, -9) and the radius is 5

Answer:

(x-6) (x-4)

Step-by-step explanation:

Its a quadratic equation, You need to find the values that multiply to get 24 and that add to -10. In this case, its (x-6) (x-4). You can check this by using foil.

The given expression should be equivalent to the (x - 6) and (x - 4)

Since the equation is

[tex]x^2 -10x + 24\\\\x^2 - 6x - 4x + 24\\\\[/tex]

x (x - 6) - 4(x - 6)

(x - 4) (x - 6)

Therefore, we can conclude that The given expression should be equivalent to the (x - 6) and (x - 4)

Answer:

I. sec G = 4/3

II. cot G = (3√7)/7

III. sin E = ¾

Step-by-step explanation:

Given

Right angled triangle

EG = 8

FG = 6

Required

sec G

cot G

sin E

First, the length of the three sides of the triangle must be completed.

From the attachment below, we can deduce that (by using Pythagoras theorem)

Hyp² = Adj² + Opp²

EG² = FG² + EF²

Substitute  EG = 8 and FG = 6

8² = 6² + EF²

64 = 36 + EF²

Collect like terms

EF² = 64 - 36

EF² = 28

Take square root of both sides

√EF² = √28

EF = √28

EF = √(4 * 7)

EF = √4 * √7

EF = 2 * √7

EF = 2√7.

Now, the trigonometric functions can be solved.

i. sec G.

sec is the reciprocal of cos .

So, we need to solve first for cos G

cos G = Adj/Hyp

Here, adj = 6 and hyp = 8

So,

cos G = 6/8

cos G = ¾

So,

sec G = 1/(¾)

sec G = 4/3

ii. cot G

cot is the reciprocal of tan

So, we need to solve first for tan G

tan G = Opp/Adj

Here, adj = 6 and opp = 2√7

So,

tan G = 2√7/6

tan G = √7/3

So,

cot G = 1/(√7/3)

cot G = 3/√7

Rationalise

cot G = 3/√7 * √7/√7

cot G = (3√7)/7

iii. sin E

sin E = Opp/Hyp

Here, Opp = 6

Hyp = 8

So,

sin E = 6/8

sin E = ¾

Colored Glass =

$5/ 1 sq = 60 / 12 sq

Clear Glass =

2/1 = 24 / 12

Materials =

.1/ 1= 1.2 / 12

Frame=

$4 / 1 ft = 28 / 12

ADD THE TOTALS

60+24+1.2+28 = 113.2

Students do not have enough money to cover the cost of making the window.

Given that, the window will be 3 feet tall and 4 feet wide.

The area occupied by a rectangle within its boundary is called the area of the rectangle. The formula to find the area of a rectangle is Area = Length × Breadth.

Area of a rectangle =3×4

= 12 square feet

Now, the total cost = 5+2+0.10+4

= $11.1

The cost per 12 square feet area

= 12×11.1

= $133.2

Therefore, students do not have enough money to cover the cost of making the window.

Step-by-step explanation:

Answer:

(13.26/h) cm = base

Step-by-step explanation:

Formula for area of triangle

= 1/2* base*height

Base = b

Height = h

And the area = 6.63 square centimeters

Area = 6.63cm²

6.63cm²= (1/2)*b*h

6.63*2= bh

13.26= bh

13.26/h = b

(13.26/h) cm = base
