Identify the zeros of the quadratic function! Please help

Mathematics
1 answer:
bezimeni [28]2 years ago
5 0

Answer:

-2.79, -4.21

Step-by-step explanation:

The function seen in the graph is 0.5 (x + 3.5)² - 1.

Hence,

0.5(x+3.5)^{2} -1=0\\0.5(x+3.5)^{2} =1\\(x+3.5)^{2} = 0.5\\x+3.5 = \sqrt{0.5}\\or\\ x+3.5=-\sqrt{0.5} \\

Finding the first answer,

x+3.5=\sqrt{0.5} \\x=\sqrt{0.5}-3.5\\x=-2.79 (3sf)

Finding the second answer,

x+3.5=-\sqrt{0.5}\\x=-\sqrt{0.5} -3.5\\x=-4.21(3sf)

Oksanka [162]
We can use addition and subtraction <span>to put together and separate measures of an angle and its parts by looking for the complementary or the supplementary angles. 

For example, What is the other angle in a complementary angle in which one of the angles is 45 degrees. This is how should be answered. Ccomplementary angles are two angles that forms a total of 90 degrees.
90 = A + B
90 = 45 + B
B = 90 - 45
B = 45
