what is the y-intercept for 3x^2 + 2x - 1

Answers

Answer 1

Answer:

y- intercept = - 1

Step-by-step explanation:

To find the y- intercept , let x = 0 in the equation and evaluate for y

y = 3(0)² + 2(0) - 1 = 0 + 0 - 1 = - 1

y- intercept = - 1 or (0, - 1) in coordinate form

Answer 2

Answer:

Plug x=0 into the equation and solve the resulting equation

The y-intercept:

3x^2 + 2x - 1

3(0)^2 + 2x(0)- 1

0+0-1

-1

y=−1 is intercept for y  

(0,−1)

A cube block has sides 8cm long. A cylindrical hole of radius 3.6 is drilled through the block. Find the volume of the block that remained

Answers

Answer:

186.45 cm^3

Step-by-step explanation:

Given data

Side lenght of cube block= 8cm

Radius of cylindrical hole= 3.6cm

Volume of entire Shape= l^3

Volume of entire Shape= 8*8*8

Volume of entire block= 512cm^3

Volume of cylindrical hole= πr^2h

Volume of cylindrical hole= 3.14*3.6^2*8

Volume of cylindrical hole= 3.14*12.96*8

Volume of cylindrical hole= 325.55cm^3

Hence the volume of the block

=volume of entire shape- volume of cylinder

=512-325.55

=186.45 cm^3

Answer:

Table D

Step-by-step explanation:

Looking at the tables, we observe that:

A. Total number is 27, but should be 17 ⇒ incorrectB. First column total is wrong; 2 + 5 = 10 ⇒ incorrectC. Total is 19, but should be 17 ⇒ incorrectD. All look correct

The answer is D.

Step-by-step explanation:

Which linear function has a y-intercept of -5?

Answers

Answer: Upper right corner (northeast corner)

x-3y = 15

===================================================

Explanation:

The y intercept always occurs when x = 0.

If we plug x = 0 into 2x+y = -10 (northwest corner), then we solve for y to get...

2x+y = -10

2(0)+y = -10

0+y = -10

y = -10

We see that the y intercept here is -10, but we want -5 instead. So we can rule this out.

In the northeast corner, plugging x = 0 leads to,

x-3y = 15

0-3y = 15

-3y = 15

y = 15/(-3)

y = -5

We get the correct y intercept we're after. So we can stop here.

If you plugged x = 0 into the equation of the southwest corner, you'll get y =  5 which is fairly close but not quite what we want. The southeast corner equation leads to a y intercept of y = 5 as well.

Answer:

x - 3y = 15

Step-by-step explanation:

x - 3y = 15

-3y = -x + 15

y = 1/3x - 5

-5 is the y-intercept.

At Shoe Line, there are 132 boots, which make up 24% of the shoes in the store. At Shoe Warehouse, there are 120 boots, which make up 15% of the shoes in the store.
Which store has more shoes? Justify your answer by showing your work or the strategy you used.

Answers

Answer:

Shoe warehouse

Step-by-step explanation:

24% of ____ is 132

15% of ____ is 120

first lets solve what there is at shoe line. since 24% times something is 132, something is 132/24%. Since % means out of 100, do 132/24*100 is 550.

Next we do the same thing to get 120/15 * 100 = 800. So, there are more at shoe warehouse.

hope this helped, and brainliest would be appreciated :)

also the steps to doing it.

Answers

Answer:

4

Step-by-step explanation:

I don't really know how to show the steps, but one of the easiest ways to do this is to see how many times 0.8 goes into 3.2.  So 0.8 + 0.8 + 0.8 +0.8 = 3.2  So 3.2/0.8 is 4

Or you can multiply the numerator and denominator by 10, which keeps the value of the fraction but gets rid of pesky decimals: 32/8 this should be fairly straight forward and a key reason to memorize your times tables.  8*4=32

There are 29 students in Mrs. Dixon's science class. On the last test, only 1 student earned the median score of 84.
How many students scored an 84 or lower?

A - 15
b - 14
C - 13
D - 12

Answers

Answer:

A

Step-by-step explanation:

Median can be described as the number that occurs at the middle of a set of observations.

for example, in the set of numbers, 1 2 3 4 5, the median is 3

median = (first number + last number) / 2

If there are 29 students,

median = (1 + 29) / 2 = 30/2 = 15

the 15th students scored 84

and students between 1 - 14 scored lower than 84

so, 15 students scored an 84 or lower

Calculate the volume of the composite solid.

Answers

Answer:

about 33.52 in^3

Step-by-step explanation:

Volume of composite figure = volume of cone + volume of hemisphere

Volume of a cone = 1/3(nr^2h)

n = 3.14

r = radius  

h = height

1/3 x 3.14 x 2^2 x 4 = 16.74 inches^3

volume of a hemisphere = (2/3) x (n) x (r^3)

n = 3.14

r = radius

2/3 x 3.14 x 2^3 =  16.74 inches^3

16.74 inches^3 +  16.74 inches^3 = 33.49

Your value of z is 71 degrees. The value of x is 11.

Step-by-step explanation:

You can determine the value of z by knowing that z and the 71 angle are vertical angles. Vertical angles are congruent to each other. We know that the x angle and the 71 angle are supplementary, or that they equal 180. So, set up the equations, and solve for x. :
