find the x-intercepts of the function g(x)=8x^{2} −10x−3
Answer: [tex][-\frac{1}{4}, \frac{3}{2}][/tex]
Step-by-step explanation:
Factor:
[tex]g(x) = 8x^{2} -10x-3[/tex][tex]g(x) = x^{2} -10x-24[/tex] ---> multiply constant (3) by coefficient of first term[tex]g(x) = (x+\frac{2}{8})(x-\frac{12}{8} )[/tex] ---> factor (multiplies to 24 and adds to -10. Divide factors by 8 since you multiplied by 8 in previous step)[tex]g(x) = (x+\frac{1}{4})(x-\frac{3}{2})[/tex] ---> simplify[tex]g(x) = (4x+1)(2x-3)[/tex] ---> move denominator of fraction to be coefficient of xSolve:
[tex]0 = (4x+1)(2x-3)[/tex] ---> set equation equal to 0.[tex]0 = 4x + 1[/tex] ---> make each parentheses equal to 0.[tex]-1 = 4x[/tex] [tex]-\frac{1}{4} = x[/tex] ---> x intercept[tex]0 = 2x - 3[/tex] [tex]3 = 2x[/tex] [tex]\frac{3}{2} = x[/tex] ----> x interceptNelson is planning out his monthly budget and estimates that he spends $250 on food each month. When he got his bank statement, he discovered that his actual food expense for the month was $315. Calculate his percent error. Round to the nearest whole percent.
Answer:
21
Step-by-step explanation:
250 / 315 = 0.79
0.79 x 100 = 79
100 - 79 = 21

But it's 120+20[tex]\pi[/tex]
Because the 3 boxes in the middle are cubes, all three are 10x10, and perimeter of a cube is each side added up.
All together it would be 40+40+40 which equals 120.
Then for the semi-circles, the perimeter formula is 1/2([tex]\pi[/tex]d) d standing for diameter. Since we can tell that the diameter takes up 2 full cubes, we know that the diameter is 20. However since it's a semi-circle we cut that in half. So 10[tex]\pi[/tex]
10[tex]\pi[/tex]+10[tex]\pi[/tex]=20[tex]\pi[/tex]
So then your final answer is 120+ 20[tex]\pi[/tex]

Answer:
The measure of the first angle is 32° and the measure of the second angle is 49°. (h = 32° & c = 49°)
Step-by-step explanation:
For the first triangle, we know that when you add up all the angles in a triangle, you'll end up with 180°. Keeping that in mind, all you have to do to find the third angle is add up the two we already know and subtract it from 180°.
1. 58° + 90° = 148° --> I know that the second angle is 90° because it's a right
180° - 148° = 32° triangle.
2. 82° + 49° = 131°
180° - 131° = 49°
Hope this helps,

Which of the relationships below represents a function with the same rate of change as the function y=x-4?
Answer:
D
Step-by-step explanation:
The slope for the first one is 1 since x stands alone. You have to find the slope for each, and find the one that matches, so divide the change in y over change in x, or for the graphs find where the points are, find the difference in the y and x values and do change in y over change in x. For A, the slope would be -1, so it wouldn’t work. For B, the slope would be -5/4, so it wouldn’t match. For C, the slope would be -4/2, so it wouldn’t be a match. D the slope would be 1 so it is the only one that matches.

Evelyn is a member of her school’s track team. She competes in the mile run. Last week in practice Evelyn ran 3 1/4, 2 1/8, 2 7/8, 1 3/4, and 1 3/4miles.
A. Estimate how many total miles she ran in practice last week.
B. Exactly how many miles did Evelyn run last week in practice?
Answer:
A. You have to complete your own estimation however, by looking at it, mine is about 11 miles.
B. 11.75 or 11 3/4 miles
We can estimate that Evelyn ran about 11.5 miles in practice last week and Evelyn ran exactly [tex]11\frac{3}{4}[/tex] miles in practice last week.
What is Fraction?A fraction represents a part of a whole.
To estimate how many total miles Evelyn ran in practice last week, we can round each of the distances to the nearest half-mile and add them up:
[tex]3\frac{1}{4}[/tex] = 3.5, [tex]2\frac{1}{8}[/tex] = 2, [tex]2\frac{7}{8}[/tex] =3, [tex]1\frac{3}{4}[/tex] =1.5 and [tex]1\frac{3}{4}[/tex]=1.5
Adding these rounded distances, we get:
3.5 + 2 + 3 + 1.5 + 1.5 = 11.5
Therefore, we can estimate that Evelyn ran about 11.5 miles in practice last week.
The exact total number of miles Evelyn ran last week in practice, we need to add up the distances exactly.
[tex]3\frac{1}{4}[/tex] =13/4,
[tex]2\frac{1}{8}[/tex] = 17/8,
[tex]2\frac{7}{8}[/tex] =23/8,
[tex]1\frac{3}{4}[/tex] =7/4 and
[tex]1\frac{3}{4}[/tex]=7/4
Adding the fractions, we get:
[tex]\frac{13}{4} +\frac{17}{8}+\frac{23}{8}+\frac{14}{8}+\frac{14}{8}[/tex]
LCM of denominators is 8
[tex]\frac{26}{8} +\frac{17}{8}+\frac{23}{8}+\frac{14}{8}+\frac{14}{8}[/tex]
= [tex]\frac{94}{8}[/tex]
Evelyn ran exactly [tex]11\frac{3}{4}[/tex] miles in practice last week.
Hence, we can estimate that Evelyn ran about 11.5 miles in practice last week and Evelyn ran exactly [tex]11\frac{3}{4}[/tex] miles in practice last week.
