Answer:

(a) 42.25 - 13.2

(b)  The old drill would have dug 19.367 ft in the same length of time (2 hours).

Step-by-step explanation:

(a) In the two hours, 12 Noon to 2 p.m., the new drill dug

42.25 - 13.2 =

29.05 feet.  

(b) Let r = the old drill dig rate in units of ft/hour

Then, 1.5r = the new drill dig rate.

So, 1.5r (2 hours) = 29.05, so that

r = (29.05)/(1.5 * 2) = 9.6833333 ... ft/hour.

So, the answer is: 9.683333 ... * 2 = 19.367 ft, rounded to the nearest 1000th.  Thus, the old drill would have dug 19.367 ft in the same length of time (2 hours).  

The required expression and the length of hole are 1.5( 42(¹/₄) - 13.2) and 43.57 feet respectively.

In order to solve a problem for two different values of a quantity, its unit value is first derived. This method is known as unitary method.

The given problem can be solved by unitary method as follows,

(a) The expression that represents the length of hole dug by new drill is given as,

The length of hole dug by old drill in 2 hours is given as,

42(¹/₄) - 13.2

For new drill it is  1.5( 42(¹/₄) - 13.2) feet.

(b) The length of drill dug by old drill is,  

42(¹/₄) - 13.2

=  42.25 - 13.2

=  43.57 feet.

Hence, the expression for hole length by the new drill and the length of hole dug by old drill are given as  1.5( 42(¹/₄) - 13.2) and 43.57 feet respectively.

Answer:

y=3x2−2x+2

Step-by-step explanation:

Standard form of equation of a parabola is [tex]y=ax^2+bx+c[/tex]

As it passes through points (−2,18), (0,2) and (4,42), each of these points satisfies the equation of parabola and hence

18=a⋅4+b⋅(−2)+c or 4a−2b+c=18 ........(A)

2=c ........(B)

and 42=a⋅16+b⋅4+c or 16a+4b+c=42 ........(C)

Now putting (B) in (A) and (C), we get

4a−2b=16 or 2a−b=8 and .........(1)

16a+4b=40 or 4a+b=10 .........(2)

Adding (1) and (2), we get 6a=18 or a=3

and hence b=2⋅3−8=−2

Hence equation of parabola is [tex]y=3x^2 -2x+2[/tex] and it appears as shown below

Given function:

Find its inverse, substitute x with y and f(x) with x:

Substitute y with f⁻¹(x):

Correct choice is B

Interchange x and y and solve for y

That's the inverse

Option B

B= (3,6) and D= (18,9)

Step-by-step explanation:

To find the midpoint of two given points add X1 and X2 together, then divide by 2 to get the X value of the midpoint and do the same thing for the Y value. That will get you B. From there you can see to get from point A to point C you add 10 to the x value and add 2 to the y value. Because C is the midpoint just double what you had to add to get point D (add 20 to x and add 4 to y)

Answer:

D

Answer:

If PQRS is a parallelogram, then — PQ ≅ — RS and — QR ≅— SP . If a quadrilateral is a parallelogram, then its opposite angles are congruent. If PQRS is a parallelogram, then ∠P ≅ ∠R and ∠Q ≅ ∠S.

PQ=RS and PQ||RS implies PQRS is a parallelogram by showing that the diagonals bisect each other at O.

A quadrilateral with opposite sides equal and parallel but the angles are not right angle is called parallelogram.

Given that PQ=RS and PQ||RS .

Draw the parallelogram PQRS as in figure

To prove: PQRS is a parallelogram.

Construction: Join PS and QS as diagonals.

From the ΔORS and ΔOPQ,

PQ=RS (Given)

∠SOR=∠POQ   (opposite angles)

∠PQO=∠OSR  (since PQ=RS and PR is a traversal)

∴ΔOQS≅ΔOPQ

Hence, Op=OR and OQ=OS

Therefore , the diagonal of quadrilateral PQRS bisects each other.

Hence the given quadrilateral PQRS is a parallelogram.

It's 2 4 7

Step-by-step explanation:

The first column says "one number is correct and well placed," so it's number two, because the third column says "One number is correct but incorrectly placed," which means number 2 is in the same place, and number 4 is in the last, but the fourth column says "Two numbers are correct but incorrectly placed," means 4 and 7 are in the first and second columns, but supposed to be in the 2nd and 3rd place, respectively. As a result, it's 2, 4, 7, and I hope you understand because I'm terrible at explaining things.

So, the sum of the 3 angles in a triangle is 180.

What you would do is:

180= 73+6x-4+7x+7.

Then, you add the common coefficients:

180=76+13x

Then you subtract:

104=13x

Then you divide:

x=8.

Then substitute the x value into the A value to get 44, meaning that C is the correct answer.
