Use a graphing calculator to approximate the zeros of the function. Round to the nearest hundredth, if necessary.
f(x) = 4x² + 4x – 35

-2.5 and 3.5
a. -2.5 and -3.5
b. 2.5 and -3.5
c.
d. no zeros

step-by-step explanation:

this is not possible to solve with the info given.   you need at least an one angle somewhere.

answer: i'm not sure

step-by-step explanation:

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
