Answer:
Step-by-step explanation:
AC² = AD² + DB ²
25 = AD² + 9
AD²= 25 - 9
AD² = 16
AD = 4
Area = 4*3 /2
= 6cm
The differentiation of the function g(t) = 7/t⁴ will be equal to g¹(t)=-28/t⁵
<h3>What is differentiation?</h3>
The method of determining the derivative, or rate of change, of a function in mathematics.is termed as the differentiation.
Given that:-

The derivative will be calculated as:-

Therefore the differentiation of the function g(t) = 7/t⁴ will be equal to g¹(t)=-28/t⁵

Answer:
ok
Step-by-step explanation:
Answer:
Step-by-step
i) a² - 2ab + b² = (a + b)²
a² = p² ; a = p
b² = 16 = 4² ; b = 4
2ab = 2*p*4 = 8p
p² - 8p + 16 = (p - 4)²
ii) a² + 2ab + b² = (a +b)²
a² = 121x² = (11x)² ; b² = 4y² = (2y)²
2ab = 2 * 11x * 2y = 44xy
121x² + 44xy + 4y² = (11x + 2y)²
Answer: 30
Step-by-step explanation:
105 + 45 =150
180 - 150 = 30
30 +90 = 120
180 - 120 = 60
2x = 60
x =30
