For what values of x will the function f(x) = 3x² + 13x - 10 equal zero?

Mathematics

Answer:

x = - 5 , x = \frac{2}{3}

Step-by-step explanation:

the values of x that make f(x) zero are the zeros

to find the zeros let f(x) = 0 , that is

3x² + 13x - 10 = 0

consider the factors of the product of  the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.

product = 3 × - 10 = - 30 and sum = + 13

the factors are + 15 and - 2

use these factors to split the x- term

3x² + 15x - 2x - 10 = 0 ( factor the first/second and third/fourth terms )

3x(x + 5) - 2(x + 5) = 0 ← factor out (x + 5) from each term

(x + 5)(3x - 2) = 0

equate each factor to zero and solve for x

x + 5 = 0 ⇒ x = - 5

3x - 2 = 0 ⇒ 3x = 2 ⇒ x = \frac{2}{3}

Carlolyn determines that the area of a white triangle is half the area of a shaded triangle because the ratio of the side length
rjkz [21]
Ok so

area=1/2 times base times height
lets say base and height=3 for one triangle and
base and height=6 for another
area1=1/2 times 3 times 3=9/2
area2=1/2 tmes 6 times 6=18
areas are

9/2 to 18=9:36=1:4
3:6=1:2
is 1:2=1:4? no

ratio is 1:4

Step-by-step explanation:
Given : Number = 8
To Find : find the square root of 8 upto 2 decimal places​
Solution :
We are supposed to find the square root of 8
Group the digits into pairs
For digits to the left of the decimal point, pair them from right to left.
For digits after decimal point, pair them from left to right).
So, we have , 08
Refer the attached figure for further steps
√8 = 2.828
Hence the square root is 2.828
Since , you asked for 2 decimal places so the answer is:
Answer:
2.82
Step-by-step explanation:
√8=2*√2= 2*1.41= 2.82

ratelena [41]

Answer:

D is not a supported statement

Step-by-step explanation:

Let take them one by one:

A: from table: 0.57; in statement: 0.5

0.57 > 0.5 so this is supported

B: from table: 0.2+0.16=0.36; in statement: 1/3=0.33,

0.36>0.33 so this is supported

C: 0.07 is the least, so this is supported

D: the table DOES NOT show number of students, but proportions. So statement '7 students' IS NOT supported

E: from table 0.20 overslept. 0.2 < 1/4=0.25, so this is supported
