1. P(x)=x^2+2 2. P(x)= 2x +10

Mathematics
1 answer:
ruslelena [56]4 years ago
4 0

Answer:

see explanation

Step-by-step explanation:

Since p(x) = x² + 2 , if x ≤ 4

For x = 4 then this is included in the inequality x ≤ 4

whereas x > 4 does not include x = 4 but values greater than 4

Thus to evaluate x = 4 use p(x) = x² + 2

Write the percent as a decimal.
Alinara [238K]

Answer:

12% = 0.12

Percent means 'per 100'. So, 12% means 12 per 100 or simply 12/100. If you divide 12 by 100, you'll get 0.12

A right triangle has base x meters and height h meters, where h is constant and x changes with respect to time t, measured in se
aksik [14]

The relationship between dθ/dt, the rate of change of θ with respect to time, and dx/dt, the rate of change of x with respect to time is \frac{d\theta}{dt}  = \frac{h}{x\sqrt{x^2+y^2} }\frac{dx}{dt}

Given the following parameters:

  • Adjacent side = x
  • Opposite side = h
  • The angle of elevation = θ

According to SOH CAH TOA identity;

tan \theta =\frac{Opposite}{Adjacent}

Substitute the given values into the formula

tan \theta =\frac{h}{x}

\theta= tan^{-1}\frac{h}{x}

Differentiate with respect to x

\frac{d \theta}{dx} = \frac{h}{x\sqrt{x^2+y^2} }

According to the chain rule,

\frac{d\theta}{dt} =\frac{d\theta}{dx} \times \frac{dx}{dt}\\\frac{d\theta}{dt}  = \frac{h}{x\sqrt{x^2+y^2} }\frac{dx}{dt}

Hence the relationship between dθ/dt, the rate of change of θ with respect to time, and dx/dt, the rate of change of x with respect to time is \frac{d\theta}{dt}  = \frac{h}{x\sqrt{x^2+y^2} }\frac{dx}{dt}

A hamster weighs 100 grams, and it eats 200 decigrams of food. How many decigrams does the hamster weigh after eating?
Rina8888 [55]
1 gram is 10 decigrams so 200 divided by 10 is 20 and 100 plus 20 is 120 and 120 multiplied by 10 is 1,200 so it now weighs 1,200 decigrams
