Consider the quadratic function f(x) = -2x^2 + 5x – 4. The leading coefficient of the function is​

Answer:

11) 9

12)10.27

13)4.05

14)8.1

Step-by-step explanation:

In Δ LMN

angle N = 90 degrees, angle L = 45 degrees

The sum of measures of a triangle is 180 degrees.

45 + 90 + angle M = 180

angle M = 180 - (90+45)

angle M = 45 degrees

This goes under 45 - 45 - 90 degree theorem,

therefore, This is an isoceles triangle.

Therefore the two adjacent sides would be equal.

11) LN = MN

if LN = 9

then, MN = 9

This goes under 45 - 45 - 90 degree theorem,

12) LM = 1/√2 * LM ............(hypotenuse)

9 = 1/√2 * LM

LM = 9 * √2

LM = 9 * 1.414. ........(as value of √2 is 1.414)

therefore, LM = 10.27

In Δ OPQ

angle Q = 90 degrees, angle P = 60 degrees

The sum of measures of a triangle is 180 degrees.

60+ 90 + angle O = 180

angle O = 180 - (60 + 90)

angle O = 30 degrees

This goes under 30 - 60 - 90 degree theorem,

14) side opposite to 60 degree is OQ,

OQ = √3/ 2 * OP

7 = √3 / 2 * OP

OP = 7* 2 / √3

OP = 14/ √3

OP = 8.1

13) This goes under 30 - 60 - 90 degree theorem,

side opposite to 30 degrees is PQ,

PQ = 1/2 * OP

PQ = 1/2 * 8.1

= 4.05

Answer: $48.06

Step-by-step explanation:

Simply take the sales price minus the unit cost, and divide that number by the unit cost. Then, multiply by 100 to determine the markup percentage. For example, if your product costs $50 to make and the selling price is $75, then the markup percentage would be 50%: ( $75 – $50) / $50 = . 50 x 100 = 50%.

Answer:

You would pay $48.06

Step-by-step explanation:

27*0.78 = 21.06

27 + 21.06 = 48.06

Answer:

D. One square and four triangles

Step-by-step explanation:

Cece is finding the surface area of a square pyramid by finding the sum of the areas of its faces

Square pyramid has a square base.

each edge of the square base joins at the top of the vertex to make a pyramid

The sides of the pyramid is a triangle

the square has 4 sides, so four triangle on the sides of the pyramid

Hence one square and four triangles forms a square pyramid

We multiply two because the ration for adults is 2

We are to check the options and choose which applies to the triangle

The options which applies is option C, Scalene and option For, Acute

Obtuse: It is not an obtuse angle because none of the angles are greater than 90°

Isosceles: It is not an isosceles triangle because it has no two equal sides

Scalene: It is a scalene triangle because all the sides are not equal sides

Equilateral: It is not an equilateral triangle because all the sides are not equal

Right: It is not a right angle because none of the angles form a straight line equivalent to 90°

Acute: It is an acute angle because the angles measures less than 90°

The correct answer is Scalene and acute

Answer:

700

Step-by-step explanation:

1/2 Square equals to 1/4 equals to x over 5 2 Square

therefore 1/4 equals to x over 5 2 square

Equals to 1/4 equals to x over 5 * 4 you know that 2 square equals to 4

So now I'm going to solve for 1/4 equals to x of over 5 * 4 equals to 20

1/4 equals to x over 20

1/4 equals to 20 cross multiply

= 1\4 = x/20

= 4 * x = 20*1

4x = 20

divide both side by the coefficient of x

4x/4 = 20/4

x =5

Answer: 1/20

Step-by-step explanation:

1/20 liters because 5 times 4/1 (5 divided by 1/4) equals 1/20

Answer:

5

Step-by-step explanation:

Ask your self which equation you should use. Since it says F(3) then we have to find an equation that would fit this correctly. For example if we look at -X^2, X<-2 we could see that 3 is clearly not less than -2, leading to the conclusion that this is not the right equation.. If you look at the last equation it says that x has to be greater/equal to 0 which is true. So then we are left with the equation...

F(3)=x+2

F(3)=3+2

F(3)=5

Answer:

110cm

Step-by-step explanation:

With the slice, we know that we need to find the area of a triangle with a base of 10cm and a height of 22cm.

Let 10 be x and 22 be y.

Substitute this into the equation for finding the area of a triangle.

[tex]\frac{x*y}{2}[/tex]

Which now becomes

[tex]\frac{11*20}{2}[/tex]

Which now becomes

[tex]\frac{220}{2}[/tex]

Now solve.

[tex]\frac{220}{2} = 110[/tex]

Your answer is 110cm.
