Mathematics
1 answer:
zhuklara [117]3 years ago
5 0

Answer:

see below

Step-by-step explanation:

9 ^-5 * 9^-3

When multiplying these we ADD the exponents:

9^-5 * 9^-3

= 9^(-5 + -3)

= 9 ^-8

= 1/9^8  Option A


2.    2^14 / 2^7   This is a division so we SUBTRACT the exponents:-

= 2^(14 - 7)  

= 2^7   (answer)

3.    If the triangle is a right angled one then it will obey Pythagoras Theorem so:-

13^ = x^2 + 5&2

x^2 = 13^2 - 5^2

x^2 = 144

x = 12    (answer)


4.   The last choice is a crucial step.

The total area of the triangles is the same in both large squares so  the area of the large  square e^2 = a^2 + b^2 ( the 2 squares in the left side large square).

What is the solution set -4.9x +1.3 > 11.1
Irina18 [472]

Answer:

x < - 2

Step-by-step explanation:

given - 4.9x + 1.3 > 11.1 ( subtract 1.3 from both sides )

- 4.9x > 9.8 ( divide both sides by - 4.9 )

Remembering to reverse the direction of the inequality symbol as a result of dividing by a negative quantity.

x < - 2 ← inequality reversed

solution set : x ∈ ( - ∞, - 2 )

tiny-mole [99]

Step-by-step explanation:

By the formula of slope, we have

( \frac{y  _{2}  - y_{1} }{x _2 - x _{1} }) \\ (  \frac{ - 1 - 1}{ - 2 - 6}  ) \\ ( \frac{ - 2}{ - 8} ) \\ (  \frac{1}{4} )
