Answer:

x-intercepts -1, 5.

Vertex is at (2, -9).

Step-by-step explanation:

y = x^2 - 4x - 5

Completing the square:

y = (x - 2)^2 - 2^2 - 5

y = (x - 2)^2 - 9   which is vertex form.

So the coordinate of the vertex are (2, -9).

Finding the x-intercepts:

(x - 2)^2 - 9 = 0

(x - 2)^2 = 9

x - 2 = +/- 3

x =  3 + 2  or -3+2

= 5, -1.

Given:

Volume of a cube = 1.5 m³

To find:

The length of its edge to the nearest tenth of a meter.

Solution:

Let a be the length of its edge.

We know that, volume of a cube is

[tex]V=a^3[/tex]

where, a is edge.

Volume of a cube = 1.5 m³

[tex]a^3=1.5[/tex]

Taking cube root on both sides, we get

[tex]a=\sqrt[3]{1.5}[/tex]

[tex]a=1.14471424[/tex]

Approximate the value to the nearest tenth (one decimal place) of a meter.

[tex]a\approx 1.1[/tex]

Therefore, the length of the edge of the cube is about 1.1 meters.

Answer:

B is the correct answer

Answer: It took Sandy 11 hours to travel the same distance that Sam took 5 hours. {{{R[s]*11=5*75}}}

{{{R[s]=(5/11)*75}}}

{{{R[s]=34.9}}}{{{mph}}}

Don't ask sometimes i don't make sense...

The final answer is 11 hours... Hope this helps... Stay safe and have a great weekend!!! :D

Answer:

68 1/3

Step-by-step explanation:

Going 82 mph faster for 5 hours, Mary closed a (82 mi/h)×(5 h) = 410 mile gap. That gap was created in 3 hours by Sandy going.

 (410 mi)/(6 h) = 68 1/3 mi/h

Answer:

The quotient of: [tex]\frac{2.64\cdot 10^{-3}}{8.0\cdot 10^0}[/tex] is: [tex]\mathbf{3.3\times 10^{-4}}[/tex]

Step-by-step explanation:

We need to find quotient of: [tex]\frac{2.64\cdot 10^{-3}}{8.0\cdot 10^0}[/tex]

We know that [tex]10^0=1[/tex]

Now solving:

[tex]\frac{2.64\cdot 10^{-3}}{8.0\cdot 10^0}\\=\frac{2.64\cdot 10^{-3}}{8.0}\\=\frac{0.00264}{8}\\=0.00033[/tex]

Writing it in scientific notation

[tex]0.00033\\=3.3\times10^{-4}[/tex]

So, the quotient of: [tex]\frac{2.64\cdot 10^{-3}}{8.0\cdot 10^0}[/tex] is: [tex]\mathbf{3.3\times 10^{-4}}[/tex]

Answer:

Cookie=0.5, Apple=1.5, sandwich= 3

Step-by-step explanation:

Lets say cookie = x, then sandwich = 6x since sandwich is 6 times more expensive, apple = 3x. function: 6x+3x+x =5

                                                                 10x=5

                                                                    x=0.5

Answer:

The cookie costs $0.50, the apple costs $1.50, and the sandwich costs $3.

Step-by-step explanation:

I multiplied 0.50 by 3 (for the apple) and got 1.50, then I multiplied 0.50 by 6 (for the sandwich) and got 3. I then added them all together and got 5.

Step-by-step explanation:

daffy + duck = Daffy Duck :)

Answer:

-8

Step-by-step explanation:

Turn the equation into slope intercept form [ y = mx + b ]

y + 11 = 2(x + 1.5)

~Distribute right side

y + 11 = 2x + 3

~Subtract 11 to both sides

y = 2x - 8

"b" represents the y-intercept, so, the y-intercept is -8.

Best of Luck!

answer: x = 18

have:

75 + 6x - 3 = 180

<=> 6x = 180 +3 -75 = 108

<=> x = 108/6 = 18

Answer:

x=19

Step-by-step explanation:

Basic Algebra.

x - 13 = 6

Simply move the 13 to the right side.

This involves changing the sign to positive, due to it being a negative integer.

The resulting outcome is

x = 13+6

Which concludes to

x=19

Answer:

SRQ=24°

QTS=30°

RST=60°

RSQ=30°

Step-by-step explanation:

All angles in a triangle will always=180.

First we will find RQT

30+24+Q=180

Subtract 54 from each side

Q=126

Since All lines meet in the middle at Q, then each if those angle measures are equal.

We'll find SRQ first:

We don't know S but we know R is 24 and Q is 126

126+24+S=180

subtract 150

S=30°

QTS:

It tells us that T is 70° so that's all we need for this

RST:

We found half of S which was 30, so 30•2= 60 so RST=60

RSQ:

We already found the half of S which was 30°

Answer:

The 6.5​-ounce cans offer the largest size at a fair cost and is the best to buy.

Step-by-step explanation:

Size of the 4.5​-ounce cans of tuna in package = 4.5 × 3 = 13.5 ounce

Cost of the package= ​$4.32

Size of the 3.5​-ounce cans = 3.5 × 4 = 14 ounce

Cost of the package= ​$3.92

Size of the 6.5​-ounce cans = 6.5 × 5 = 32.5 ounce

Cost of the package= ​$9.75

The 6.5​-ounce cans offer the largest size and is the best to buy.

Step-by-step explanation:can i have brainliest?

Answer:

I will answer in English.

Here, we want to find all the 3-digit multiples of 5, that can be formed with the digits:

a) 5, 7, and 8. (i suppose that we can not repeat the digits)

First, we know that all the multiples of 5 end with a 5 or a 0, then the possible ones here are:

875

785

(the five must always be at the end)

b) 0, 3, and 5.

Now we have two options, if the 5 is at the end, we have:

305

(035 is not an option, because is a 2-digit number).

if 0 is at the end, we have:

350

530

Answer: (2, 0)

When y hits zero, that's where you can find the zero thing
