H(x)=x²-5 Find h(-7)

Mathematics

Answer:

h (-7) = 44

Step-by-step explanation:

when working with a function, when we place a value, replacing x, in parentheses next to the function, we are to find the function by replacing x with that value.

Essentially, we need to replace x with -7. [replace meaning substitute]

h (x) = x² - 5

h (-7) = (-7)² - 5

h (-7) = 49 - 5

h (-7) = 44

so, h (-7) = 44

note: ² means to square a number (to multiply that number by itself)

(-7)² ->  - 7  ·  - 7 = 49

hope this helps!!

Answer:

h(x) = 44

Step-by-step explanation:

h(x) = x² - 5, h(-7) means x = -7

h(x) = (-7)² - 5

h(x) = 49 - 5

h(x) = 44

The density of glass is 2.6 g/cm3 and the density of lead is 11.3 g/cm3. Does this mean there are more particles of lead in 1 cm
Colt1911 [192]
The answer is that there are more particles in 1 cubic cm. this is because within 1 cubic cm lead has 11.3g in compared to the 2.6 glass has. m/v= density. divide the masses over the volume and that will prove your answer.

mrs_skeptik [129]

Answer:

(Measure ) L+W :  11 and 8 inches.

These L + W measures are of each triangle and when either halved as proven below will show (A): 44inch^2

Step-by-step explanation:

Two congruent triangles of 44 sq inch = base 8  height  11  

or base 11 height 8

Finding that both numbers find the same area.

Note for future areas either measure for triangle base + height

8 x 11 or 11 x 8 = 88  when halved its the same answer.  

where 7 x 10 = 35

13 x 10 = 65

and so on;

No other number multiplies its length and height to show 44
