Answer:

A general exponential equation is written as:

f(x) = A*(r)^x

Where:

A is the initial value, this is the value that the function takes when x = 0.

r is the rate of growth

x is the variable.

In this case, the function is:

f(x) = 2*(4)^x

The initial value is:

f(0) = 2*(4)^0 = 2*1 = 2

The initial value is 2.

And the rate of growth is 4.

So Martin seems to mixed these two values (he said initial value = 4, and rate  = 2, which is the opposite of what we found)

Step-by-step explanation:

here's your solution

=> cost of 10 apple = $ 8.95

=> cost of 1 apple = $8.95/10 = $ 0.895

=> cost of 4 apple = $ 0.895*4

=> cost = $3.580

Answer:

The error in rounding a number is half of the unit of measure. The number was rounded to the nearest 0.1 unit so the error is half of 0.1 which is 12⋅0.1=0.05

​  

⋅0.1=0.05. Since 3.7+0.05=3.753.7+0.05=3.75 and 3.7−0.05=3.653.7−0.05=3.65, then the error interval is \boxed{3.65\le x<3.75}.

Answer:

m<3 = 97

m<10 = 97

m<9 = 83

m<5 = 97

m<7 = 83

m<16 = 97

Step-by-step explanation:

m<3 = m<2 because of vertical angles

m<10 = m<2 because of corresponding angles

m<9 + 97 = 180

m<9 = 83

m<5 + 83 = 180

m<5 = 97

m<7 = m<6 because of vertical angles

m<16 = m<5 because of alternate exterior angles.

Answer:

[tex]2\dfrac{1}{3}\ \text{cups}[/tex]

Step-by-step explanation:

Amount of chopped onions required = [tex]3\dfrac{2}{3}\ \text{cups}[/tex]

Amount of onions Katrina has already chopped = [tex]1\dfrac{1}{3}\ \text{cups}[/tex]

Amount of onions that are required to be chopped is given by

[tex]3\dfrac{2}{3}-1\dfrac{1}{3}\\ =\dfrac{11}{3}-\dfrac{4}{3}\\ =\dfrac{7}{3}\\ =2\dfrac{1}{3}\ \text{cups}[/tex]

Hence, the amount of onions that are required to be chopped is [tex]2\dfrac{1}{3}\ \text{cups}[/tex].

Step-by-step explanation:

first, group the terms with the same power together and it would become (-9n⁵-4n⁵)+(n³-9n³)+(11n+6n). then, combine the terms in each group together which would get -13n⁵-8n³+17n as the answer

Explanation:

The vectors representing the diagonals are ...

  AC = C - A = (9, -3) -(-3, 1) = (12, -4)

  BD = D - B = (2, -4) -(4, 2) = (-2, -6)

The dot-product of these vectors is the sum of the products of corresponding coordinates:

  (12)(-2) +(-4)(-6) = -24 +24 = 0

When the dot-product is zero, the vectors are perpendicular. These vectors are different lengths (BD = 1/2·AC), so they are not the diagonals of a square.

__

The midpoints of the diagonals will be in the same place if the quadrilateral is a rhombus.

  (A +C)/2 = (B +D)/2

We can simplify our effort a bit by multiplying by 2.

  A+C = B+D

  (9, -3) +(-3, 1) = (2, -4) +(4, 2)

  (6, -2) = (6, -2) . . . . . . . . . . . . . . . . yes, the midpoints are the same point

__

We have shown the diagonals of the quadrilateral are different lengths and perpendicular bisectors of each other, so the quadrilateral IS A RHOMBUS, NOT A SQUARE.

$60,000

Step-by-step explanation:

Given data

Base salary=$35000

commssion= 10%

Sales=  $250,000

Let us find the commission

=10/100* 250,000

=0.1*250,000

=25000

Hence the total income is

=25000+35000

=$60,000

Answer:

Area of the cabinet to be painted =    56 ft²

Step-by-step explanation:

The cabinet is shown in the diagram. To find the surface area of the cabinet we will find the surface area of the rectangular cuboid.

Surface Area= 2 lb+ 2hb + 2lh

where l = length , b= breadth and h= height.

From the figure we see that the area of the bottom is given by length * breadth  so deducting this from the total surface area of the cuboid gives the surface of the cabinet.

Area of the cabinet  to be painted=  lb+ 2hb + 2lh

Putting the values we get

Area of the cabinet to be painted =  lb+ 2hb + 2lh

                                              = 3* 1 1/3 + 2( 6 * 1 1/3) + 2( 3* 6)

                                                = 3* 4/3 + 2( 6 * 4/3) + 2( 3* 6)

                                              = 4+ 2(8) +2(18)

                                               = 4+16+ 36

                                               56 ft²

This is the outside area of the cabinet which is found front,back, top and two sides that need to be painted.

Step-by-step explanation:

The sum of the temperatures is S = -2°C

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

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

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.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

Let the temperatures on different days be represented by the table

Now , total temperature is S = -6 + 3 + 4 - 2 - 1

On simplifying the equation , we get

S = -2°C

Hence , the temperature is S = -2°C

Answer:

35 degrees and 50 degrees

Step-by-step explanation:

The sum of all the angles in a triangle must be 180 degrees. So 180 - 95 = 85 leftover for the other two angles. Since we have a ratio of 7:10, we can add that up to get 17 total pieces of that 85-degree angle. 85 / 17 = 5, so each piece is 5 degrees. Therefore, the other two angles are 7*5 = 35 degrees and 10*5 = 50 degrees.
