The temperature of a freezer started at 18 degrees Celsius.After cooling for a few hours, the freezer had a temperature of -12 degrees Celsius. What is the difference between the new,colder temperature and the original temperature?

Answers

Answer 1

Answer:

Step-by-step explanation:

Difference = New temperature - original temperature

                  = -12 - (18)

                 = - 30

New temperature is 30° less than the original temperature

Let the function f be continuous and differentiable for all x. Suppose you are given that f(−1)=−3, and that f'(x) for all values of x. Use the Mean Value Theorem to determine the largest possible value of f(5).

Answers

Answer:

Step-by-step explanation:

By MVT,

[tex]f'(c) = \frac{f(5)-f(-1)}{5-1}[/tex]

[tex]4f'(c)= f(5) + 3\rightarrow f(5) = 4f'(c) - 3[/tex]

Moreover, [tex]f'(x)\leq 4~~~~~~ \forall x,[/tex]

[tex]f(5) \leq 16 - 3 =13[/tex]

Hence the largest possible value of f(5) is 13

divide 5kg in the ratio 13:7​

Answers

Answer:

1.75 kg

Step-by-step explanation:

13/20 of 5 = 13/20 x 5= 3.25 kg

and, 7/20 of 5 = 7/20 x 5=1.75 kg

so, divide, 5 kg in ration of 13:7 is:

3.25 kg : 1.75 kg

Answer:

3.25 Kg : 1.75 Kg

Step-by-step explanation:

Sum the parts of the ratio, 13 + 7 = 20 parts

Divide the amount by 20 to find the value of one part of the ratio.

5 Kg ÷ 20 = 0.25 Kg ← value of 1 part of the ratio, thus

13 parts = 13 × 0.25  =3.25 Kg

7 parts = 7 × 0.25 = 1.75 Kg

1) 3 + 2 = 5       [Since the result is a natural number, it is a rational number]

2) [tex]\sqrt{19} + \frac{7}{2}[/tex]    [ It has a square root that cannot be simplified further so the sum of this is an irrational one ]

Rational numbers can be integers, fractions, and whole numbers.

Rational numbers can be expressed as fractions p/q, where p and q are whole numbers.

Write the equation of the line that has the indicated slope and contains the indicated point. Express the final equation in standard form. m = 1/2 , (3, 4)

Answers

Answer:

x - 2y = - 2

Step-by-step explanation:

Given the following :

1/2 , (3, 4),

The equation of a line :

y = mx + c

m = slope ; c = gradient

m = 1/2

c = (y1 - x1) / 2

c = (4 - 3) / 2 = 1/2

Hence, y = 1/2x + 1/2

In standard form:

Ax + By = C

A and B integer Coefficient of x and y respectively

y = 1/2x + 1/2

1/2x - y = - 1/2

Multiply both sides by 2

x - 2y = - 2

Hence, standard form of the equation is :

x - 2y = - 2

find the missing end point if H is the midpoint of PS. P(2,5) and H (3,4) find S (endpoint)

Answers

Answer:

(4,3)

Step-by-step explanation:

To find the midpoint add the end points and divide by 2

P(2,5)    S ( sx, sy)  and the midpoint is and H (3,4)

X coordinate

( 2+ sx) /2 = 3

Multiply each side by 2

2+sx = 3*2

2+sx = 6

Subtract 2

sx = 4

Y coordinate

( 5+ sy) /2 = 4

Multiply each side by 2

5+sy = 4*2

5+sy = 8

Subtract 5

sy = 3

The end point is

(4,3)

Answer:

[tex]\huge \boxed{\mathrm{S(4,3)}}[/tex]

Step-by-step explanation:

We can use the midpoint formula to solve for the endpoint.

The midpoint of PS is H.

[tex]\displaystyle \frac{2+x_2 }{2} =3 \ \ \ \frac{5+y_2}{2} =4[/tex]

Find the value of $B - A$ if the graph of $Ax + By = 3$ passes through the point $(-7,2),$ and is parallel to the graph of $x + 3y = -5.$

Answers

Answer:

  -6

Step-by-step explanation:

The parallel line can be written using the same x- and y-coefficients, but with a different constant:

  x +3y = constant

For the line to go through the given point, the constant must be ...

  (-7) +3(2) = constant

  -1 = constant

In order for the constant to be +3 instead of -1, the entire equation must be multiplied by -3:

  -3x -9y = 3   ⇒   A = -3, B = -9

Then the expression B-A is ...

  B -A = (-9) -(-3) = -6

The value of B - A is -6.

Take the information given and create an equation that add up to 360.

Step-by-step explanation:

You might assume the smallest angle to be the given 55, so that would make the third term 120+55. The fourth angle is unknown, x

The equation sets up as

55+65+(55+120)+x = 360

Add all the numbers to get 295.

295+x=360

Subtract 360-295 = x

x=65

The four angles are 55°,65°,175° and 65°

estimate the height of a tree using the following measurements:height of the rod:180 cm,length of the shadow of the rod is 116 cm,length of the shadow of the tree:840 cm,calculate the height of the tree

Answers

Answer:

1303.45 cm

Step-by-step explanation:

The triangles formed by a rod and its shadow and a tree and its shadow are similar triangles, so the ratios of their heights to the lengths of their shadows are equal.

Let x be the height of the tree. Setting the ratios equal, we get:

180/116 = x/840

Solve for x:

x = 840 * (180/116)

x ≈ 1303.45 cm
