A designer places 4 identical squares on a surface and spaces them 3 5/16 inches apart. Each square is 7 1/4 inches wide. If you
Anon25 [30]

Number of spaces would be number of squares - 1

You would have 12 squares and 11 spaces.

Multiply number of each by their size then add the two together:

12 x 7 1/4 = 87 inches

11 x 3 5/16 = 36 7/16 inches

Total = 87 + 36 7/16 = 123 7/16 inches

Answer: 123 7/16 inches

Grade 12<br>mathematics<br>(√98-√50)² ​
allsm [11]

Answer:

8

Step-by-step explanation:

Two different approaches:

<u>Method 1</u>

Apply radical rule √(ab) = √a√b to simplify the radicals:

√98 = √(49 x 2) = √49√2 = 7√2

√50 = √(25 x 2) = √25√2 = 5√2

Therefore,  (√98 - √50)² = (7√2 - 5√2)²

                                         = (2√2)²

                                         = 4 x 2

                                         = 8

<u>Method 2</u>

Use the perfect square formula: (a - b)² = a² - 2ab + b²

where a = √98   and   b = √50

So            (√98 - √50)² = (√98)² - 2√98√50 + (√50)²

                                      = 98 - 2√98√50 + 50

                                      = 148 - 2√98√50

Apply radical rule √(ab) = √a√b to simplify radicals:

√98 = √(49 x 2) = √49√2 = 7√2

√50 = √(25 x 2) = √25√2 = 5√2

Therefore,     148 - 2√98√50 = 148 - (2 × 7√2 × 5√2)

                                                 = 148 - 140

                                                 = 8

Write a recursive formula for a_na n ​ , the n^{\text{th}}n th term of the sequence 16, -8, 4, ...16,−8,4,....
julia-pushkina [17]

Answer:

aₙ = -2aₙ₊₁

Step-by-step explanation:

According to the sequence given 16, -8, 4, ...

a1 = 16

a2 = -8

a3 = 4

From the values, we can conclude thst;

a1 = -2(-8)

Since a2 = -8, then;

a1 = -2(a2)

Similarly

a2 = -2(4)

a2 = -2a3

The subsequent sequence are;

a3 = -2a4

The nth term will ne;

aₙ = -2aₙ₊₁

Hence the required recursive function is aₙ = -2aₙ₊₁

Find the slope of the line that passes through the points (-2, 3 ) and (5, 7) .
nika2105 [10]

Answer:

1. b. 4/7

2. c. 3

Step-by-step explanation:

To find the slope

m = (y2-y1)/(x2-x1)

m= (7-3)/(5 - -2)

   = (7-3)/(5+2)

   = 4/7

m = (y2-y1)/(x2-x1)

m= (5-2)/(2 - 1)

  = 3/1
