Given that the zeros of a quadratic function are −2 and −5, what is the standard form of the quadratic function? A) f(x) = x2 + 5x + 10 B) f(x) = x2 + 7x + 10 C) f(x) = x2 − 5x + 10 D) f(x) = x2 − 7x + 10

Answers

Step-by-step explanation:

x = -2 and x = -5

x + 2 = 0 and x + 5 = 0

(x + 2)(x + 5) = 0

x² + 5x + 2x + 10 = 0

x² + 7x + 10 = 0

f(x) = x² + 7x + 10

The  quadratic equation is x² + 7x + 10.

What is Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

We have the zeroes of Quadratic Equation as -2 and -5.

So, the factors of the equation is (x +2 ) and (x + 5).

Then, the Quadratic equation is

= (x+5)(x+2)

= x² + 5x +2x + 10

= x² + 7x + 10

Thus, the quadratic equation is x² + 7x + 10.

if a system of linear equations has infinitely many solutions

Answers

If the two lines have the same y-intercept and the slope, they are actually in the same exact line. In other words, when the two lines are the same line, then the system should have infinite solutions. It means that if the system of equations has an infinite number of solution, then the system is said to be consistent.

x = t - q

Step-by-step explanation:

because to make q, you need to add x and t

so to make x the subject, you should subtract q

Example

x + t = q

t = 7

q = 36

x = t - q

y = 12x + 2
y = 2x + 2
y = 12x + 12
y = 2x + 12

Answers

Answer:

y = 12x + 2

Step-by-step explanation:

To know:

     [] These equations are in y = mx + b form

           () Also known as slope-intercept form

           () m is the slope

           () b is the y-intercept

Now, let's solve

     [] Slope / m

           () Slope is "change in y over change in x," let hours be our x and distance by our y

           () [tex]\frac{62 - 14}{5 - 1}=\frac{48}{4}=12[/tex]

     [] Y-intercept / b

           () We will plug in a set of points into our current equation, then solve for b

           () y = mx + b -> y = 12x + b -> 14 = 12(1) + b -> 14 = 12 + b -> 2 = b

Last, we will find our answer

Our b is 2, and our m is 12. This leaves us with option 1, y = 12x + 2

Two pillars of height 8 ft each with four faces of the gate of a stadium have one-one pyramid of height 4 ft each having same base on their tops. The base of each pillar is 6 ft × 6 ft. If the pillars with pyramid are painted at rate of Rs 89 per sq.ft , what will be the total cost? [ Please include figure too]

Help!! ~Thanks in advance! :)​

Answers

Answer:

₹ 44856

Step-by-step explanation:

There are 2 pillars, two right prisms of dimensions 6x6x8 ft, two right pyramids of dimensions 6x6x4 ft on top of prisms.

There will be 4 faces of each painted.

Area of each prism face:

6*8 = 48 ft²

Total area of prism faces:

8*48 = 384 ft²

Slant height of pyramid faces:

s = √h²+(a/2)², where h- height of pyramid, a - side of bases = √4²+(6/2)²= √16+9 = √25 = 5 ft

Area of each face of pyramid:

A = (1/2)*6*5 = 15 ft²

Total area of pyramid faces:

8*15 = 120 ft²

Total area to be painted:

384 + 120 = 504 ft²

Cost of paint:

504*89 = 44856

Answers

Answer:

Step-by-step explanation:

first work out using this triangle.

distance= speed x by time

so if we're trying to find out the speed we reaarange the triangle to :

   distance

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

speed x   time

so speed = distance divided by time

distance = 45cm

divided by time = 90 seconds

But the units are cm and should be metres per second

change 45cm to m

that is 45cm = 45/ 100 = 0.45

0.45/ 90= 0.005cm

answer = 0.005 metres per second( m/s)

What is a straight line?

A straight line is a combination of endless points joined on both sides of the point.

The slope 'm' of any straight line is given by:

A linear equation has the form y = mx + b in the slope-intercept format. X and Y are the variables in the equation. The values m and b represent the line's slope (m) and the value of y when x is 0.

Triangle is scalene (indicated by the 2 dashes on the triangle)

d = 180 - (58*2)

d = 64°

c = 58°

use either 180- (64+58)

which is angles in a straight line = 180 total

or

alternate angles

b = c = 58

f) x = 50°

alternate angles

y+z = 180-50

y+z = 130

we know that y = z

scalene triangle indicated by arrows (both bases are same angle)

so 130/2 = y and z

65 = y

65 = z

g) x = 55

alternate angles

on the diagram take the triangle which has x and y

you can see 95° outside the triangle, it’s on a straight line and will help us find the third angle for that triangle

180-95 = 85

180 - (85+55) = y

y = 40

z = y = 40

alternate angles

h)

180-78 = 102

beside angle a would be the angle 2a

alternate angles (look at the photo)

180 = 102 + a + 2a

180 = 3a + 102

78 = 3a

a = 26°

2a = 52

b = 26

use either alternate angles

a = b

or total angles in a triangle = 180°

102 + b + 56 = 180

b = 180-52-102

Step-by-step explanation:

because if the towel of the width that is 3 feet less so you do 28/3=9.333

Answer:

length = 7 ft

Width = 4 ft

Step-by-step explanation:

length = l

Width = l -3

Area = 28 sq.ft

length *width = 28

l*(l-3) = 28

l*l - l*3 = 28

l² - 3l - 28 =0

l² - 7l + 4l - 28 = 0

l(l - 7) + 4(l - 7) = 0

(l -7) (l + 4) =

l -7 =  0  {Ignore l + 4 = 0 as , it gives a negative value}

l = 7 ft
