2√3 - 2√5

Using the law of radicals

√a × √b = √ab

√2(√6 - √10)

= √12 - √20

= √(4 × 3) - √(4 × 5)

= (√4 ×√3) - (√4 × √5)

= 2√3 - 2√5

  √2(√6 - √10)

= √12 - √20

= \sqrt{2*2*3} - \sqrt{2*2*5}

= 2\sqrt{3} - 2\sqrt{5}

Answer: A

The function ƒ(x) = 6x is vertically shrunk by a factor of ½ and translated 9 units in the negative y- direction. Select the cor
vredina [299]

Answer:

option C.

Step-by-step explanation:

since the graph y = 6x is shrunk by a factor of ½

it becomes y = 3x

to find one coordinate of this graph we put x = 1 so that we get y = 3

so one point we have is (1, 3).

and the other point is origin

[ for if you keep x = 0 then 3 × 0 = 0 so y comes 0 too.]

now this graph is translated 9 units in the negative y direction

so the point that initially was (0, 0) now becomes (0, -9).

we see that the only graph passing thru (0, -9) is C.

so the answer is <u>option C.</u>

What is the relationship between the conversion factors used in Part A of Model 2? Whatabout the conversion factors used in Part
Lelu [443]

Given:

The conversions from meter to inches and inches to meter are shown in part A of model 2.

The conversions from liters to quarts and quarts to liters are shown in part B of model 2.

Required:

To find the relationship between the conversion factors used in Part A of Model 2.

To find the relationship in the the conversion factors used in Part B of Model 2.

Explanation:

We have given that 1 meter = 39.4 inches.

Thus, from the calculations shown in part A of model 2, we can conclude that the quantity from meters to inches is converted as:

1.5\times39.4=59

Thus, 1.5 m =59 inches.

Also, the quantity from inches to meters is converted as:

\frac{59}{39.4}=1.5

Hence, 59 in = 1.5 m.

Next,

We have 1 L = 1.06 qt.

Thus, from the calculations shown in part B of model 2, we can conclude that the quantity from quarts to liters is converted as:

\frac{186}{1.06}=175

Thus, 186 quarts = 175 L.

Also, the quantity from liters to quarts is converted as:

175\times1.06=186

Hence, 175 L = 186 qt.

Final Answer:

We conclude that:

While converting from meters to inches, we multiply the quantity 1.5 by the equality quantity given.

While converting from incehs to meters, we divide the quantity 59 by the equality quantity given.

Also, While converting from quarts to liters, we divide the quntity 186 by the equality quantity given.

While converting from liters to quarts, we multiply the quntity 175 by the equality quantity given.

4r-3=3(3r+4) what is r
baherus [9]

Answer:

r=-3

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

4r−3=3(3r+4)

4r+−3=(3)(3r)+(3)(4)(Distribute)

4r+−3=9r+12

4r−3=9r+12

Step 2: Subtract 9r from both sides.

4r−3−9r=9r+12−9r

−5r−3=12

Step 3: Add 3 to both sides.

−5r−3+3=12+3

−5r=15

Step 4: Divide both sides by -5.

−5r

−5

=

15

−5
