Answer:

Solution given:

y=-1/2 x²

for

f(x)=-1/2 x².

differentiating each term with respect to x

f'(x)=-x

when

x=-4

f'(-4)=4>0 increasing

when

x=-2

f'(-2)=2 >0 increasing

when x=0

f'(0)=0 stationary point.

other points are decreasing

so

largest interval of increasing is

A.X<-2

Step-by-step explanation:

Part A:

(8x+6)/4= 2x+ 1.5

Part B:

72= (8x+6)

8x= 72-6

8x= 66

x= 8.25

the side length = 2x+1.5= 2(8.25)+1.5= 18 centimetres

Answer:

m = 1

Step-by-step explanation:

slope intercept form --> y=mx+b

y=1x+0

therefore the slope is

m = 1

Answer:

M< D = 105⁰

Step-by-step explanation:

the sum of the opposite angles of a cyclic quadrilateral is 180⁰

hence, <ADC + <ABC = 180⁰

<ADC + 75⁰ = 180⁰

<ADC = 180⁰ - 75⁰

< ADC= 105⁰

Answer:

B. 1.32 h : 1 point 3 2 h

Step-by-step explanation:

Year 1 = h hits

Year 2 = 132 % of the hits it received the first year

Number of hits the company's website received the 2nd year = 132% of h

= 132/100 × h

= 1.32 × h

= 1.32h

A. 1 + 0.32h : 1 plus 0 point 3 2 h,

B. 1.32 h : 1 point 3 2 h,

C. ( 1 + 1.32 ) h : open paren 1 plus 1 point 3 2 close paren times h,

D. h + 1.32 h : h plus 1 point 3 2 h,

Answer:

Answer:

x = 1.3

Step-by-step explanation:

Eliminate fractions first.  Multiply all four terms by 100.  The result will be:

380 + 450x - 140 = 825

Combine like terms:

240 + 450x = 825, or

585 = 450x, or:

x = 1.3

Propiedad distributiva de la multiplicación sobre la suma

Step-by-step explanation:

Spanish

Propiedad distributiva de la multiplicación sobre la suma

2 × (4 + 7)

Aquí vemos que el número 2 se multiplica por 4 y 7

2 se distribuye a 4 y 7

= 2 × 4 + 2 × 7

Después de la multiplicación se suman ambos

= 8 + 14 = 22

Esta propiedad se llama propiedad distributiva de la multiplicación sobre la suma.

English

No development of multiplication 2 × (4 + 7) = 2 × 4 + 2 × 7 = 8 + 14 = 22, which property was used?

Distributive property of multiplication over addition

2 × (4 + 7)

Here we see that the number 2 is multiplied with both 4 and 7

2  is distributed  to both 4 and 7

= 2 × 4 + 2 × 7

After multiplication both are added

= 8 + 14 = 22

This property is called distributive  property of multiplication over addition.

Answer:

$122

Step-by-step explanation:

Let total money in his pocket = $ x

12.5% of x = $ 15.25

[tex]\frac{12.5}{100}*x= 15.25[/tex]

Multiply both sides by 100

12.5 *x = 15.25*100

125.5 *x = 1525

Divide both sides by 125.5

[tex]x = \frac{1525}{12.5}\\\\[/tex]

x = $ 122

B 7.2

Step-by-step explanation:

the coordinate of C: (1, 3)

the coordinate of E: (5, -3)

the distance formula: [tex]\sqrt{(x2 - x1)^{2} + (y2 - y1)^{2} }[/tex]

= [tex]\sqrt{(5-1)^{2} + (-3-3)^{2}}[/tex]

= [tex]\sqrt{16+36}[/tex]

Answer:

Exterior = 22.5 degrees

Interior = 157.5 degrees

Step-by-step explanation:

Exterior angles = 360/16 = 22.5

Interior Angles = 180 - 22.5 = 157.5

Respuesta:

27,22 metros

Explicación paso a paso:

Dado :

Sombra del poste = 21 metros

Altura de la persona = 1,75 metros

Sombra de la persona = 1,35 metros

Altura del poste =?

Usando la relación:

Altura de la persona / sombra de la persona = altura del poste / sombra del poste

1,75 / 1,35 = x / 21

Cruz multiplicar

1,35 * x = 1,75 * 21

x = (1,75 * 21) / 1,35

x = 27,22

Step-by-step explanation:

Answer:

function 2 only

Step-by-step explanation:

The Function that have a slope have 1 is Function 1.

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the

change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx where, m is the slope

From function 1, the slope is

Slope = (0-2)/ (1- 3)

Slope = (-2)/ (-2)

Slope = 1

Now, for function 2 the slope is

Slope = 2

and, for Function 3 the slope is

Slope = 0

and, For function 4 the slope is

Slope = 3/2

Thus, Slope of function 1 have slope 1.

Answer:

9/2 = 4 1/2 , 2/3 = 3/2

Step-by-step explanation:

The reciprocal of a fraction is switching the numerator and the denominator.

2/3, switched is 3/2.

To find the mixed form of an improper fraction, you divide the numerator by the denominator.

Like this, 9/2 = 4.5

4 is the whole.

So, 4 would be the whole number.

Then there is 1 left over.

You keep the denominator.

So it would be 4 1/2.

Answer:

the answer is an obtuse triangle

The triangle in the image is an obtuse triangle.

In any triangle, the sum of the three angles is always 180 degrees.

Here, the sum of the two angles is 30 + 30 = 60 degrees.

Now, Adding the 120 degrees angle

= 60 + 120

= 180 degrees, which is consistent with the sum of angles in a triangle.

Now, let's consider the types of triangles:

1. Acute triangle: All three angles in an acute triangle are less than 90 degrees.

2. Right triangle: A right triangle has one angle that measures exactly 90 degrees.

3. Equilateral triangle: An equilateral triangle has all three angles equal to 60 degrees.

4. Obtuse triangle: An obtuse triangle has one angle that is greater than 90 degrees.

Thus, the triangle in the image is an obtuse triangle.

Answer:A

I just took assignment on edge.

Answer: x=-6 and x= -2/3

Answer:

The correct option is option;

A. Flip

Step-by-step explanation:

When both sides of an inequality is divided by a negative number, it changes the sign of both numbers while their magnitude remain the same;

Therefore, if the right hand side of the inequality is lesser than the left hand side, when the signs of the left and right hand sides of the inequality changes after a division , by a negative number, we have;

The smaller right hand side of the inequality will then have a lesser negative magnitude than the left hand side of the inequality with a higher negative value and the left hand side (with the higher negative value) becomes lesser than the right and therefore, the symbol (sign) of the inequality is flipped

Therefore, when you divide both sides of an inequality by a negative number, you need to flip the inequality symbol.
