LiRa [457]3 years ago
5 0

Answer:

272

Step-by-step explanation:

note that (f • g)(x) = f(x) × g(x) = (3x - 7)(4x - 5)

To evaluate substitute x = 3 into (3x - 7)(4x - 5)

(f • g)(- 3) = (- 9 - 7)(- 12 - 5) = - 16 × - 17 = 172

Yellowstone Lake, in Wyoming, is the largest high-altitude lake in North America, measuring 20 miles long and 14 miles wide. How
agasfer [191]

Answer:

6.67in long and 4.67in wide

Step-by-step explanation:

Given the amp of the scale 1 inch = 3 mi?

If the measured length is 20miles

Let x be the dimension of the length on the map

1 inch = 3 mi?

x = 20miles

3x = 20

x = 20/3

x = 6.67in

For the width,

Width =14miles

Let y be the dimension of the width on the map

1 inch = 3 mi

y = 14miles

3y = 14

y = 14/3

y = 4.67in

Hence the Yellowstone Lake appears 6.67in long and 4.67in wide on the Map

Please help solve this
notsponge [240]

Answer:

1/6

Step-by-step explanation:

so what you want to do first to create a common denominator:

1. multiply 2/3 by 2 to get a denominator of 6

2. Now you have 4/6, to solve for x you subtract 4/6 from the total

\frac{5}{6} - \frac{4}{6} = \frac{1}{6}

thats how you get your answer!

Hope this helped :)

Match the given conditions to the number of triangles that can be constructed from them. The lengths of the three sides are 4 ce
rjkz [21]

Answer:

See below  

Step-by-step explanation:

<u>No. of ∆s </u>       <u>         Conditions            </u>      

      0               Sides 4 cm, 2 cm, 7 cm

      1                ASA = 30°, 12 in, 30 cm

     ∞                Angles 25°, 75°, 60 °

Reasons:

0 — The two shorter sides are not long enough to meet and form a triangle

1 — The two angles and the included side define a single triangle. The two angles define a single point at which their opposite sides will meet.

∞ — The three angles define the shape of the triangle but not its size. You can dilate the triangle to a larger or smaller size and still have the same angles.
