Which equation is y = 6x2 12x – 10 rewritten in vertex form? y = 6(x 1)2 – 11 y = 6(x 1)2 – 10 y = 6(x 1)2 – 4 y = 6(x 1)2 – 16
The vertex form of the given quadratic equation is:
[tex]y = 6*(x + 1)^2 - 16[/tex]
How to rewrite the equation in vertex form?We have the quadratic equation:
[tex]y = 6x^2 + 12x -10[/tex]
First, we need to find the vertex. The x-value of the vertex is:
h = -12/2*6 = -1
To get the y-value of the vertex, we need to evaluate the function in h, so we get:
y = 6 - 12 - 10 = -16
Then the vertex is (-1, -16)
This means that the vertex form is:
[tex]y = 6*(x + 1)^2 - 16[/tex]

The angle k will be 100 in the triangle KJL and the side HI will be 4.
What is triangle?
A triangle is a plane figure formed by the three sides having sum of the angles 180 degree.
Here in triangle KJL we can see that it is a isosceles triangle So the angle j and angle L will be 40.
Now we can solve
[tex]\angle L + \angle J + \angle K=180\\\\\\40+40+\angle K=180\\\\\\\angle k=180-80\\\\\\\angle k=100[/tex]
Now the side HI in the triangle HGI
We can see that the triangle HGI is the equilateral triangle so the all sides will be equal so

a car travels at 49 km/hour how far does it travel in a 12 hour day
Answer: 2.88 km.
Step-by-step explanation:
We will discuss here how to find the distance when speed and time are given.
When speed and time are given, the distance travelled is calculated by using the formula:
Distance = Speed × Time
The unit of time in speed should be the same as that of the given time.
Solved examples to calculate distance when speed and time are given:
1. How much distance will be covered in 5 hrs at a speed of 55 km per hour?
Solution:
Distance covered in 1 hour = 55 km.
We know, Distance = Speed × Time
Distance covered in 5 hrs = 55 × 5
= 275 km.
Therefore, distance covered in 5 hrs = 275 km.
2. A bus travels at a speed of 45 km/hour. How far will it travel in 36 minutes?
Solution:
Speed = 45 km/hour
Time = 36 minutes
= 36/60 Hour (Since we know, 1 hour = 60 minutes)
= 3/5 hour
Distance = speed × time
= 45 × (3/5) km
= (45 × 3)/5 km
= 27 km.
3. How much distance will be covered in 7 hrs at a speed of 62 km per hour?
Solution:
Distance covered in 1 hour = 62 km.
We know, Distance = Speed × Time
Distance covered in 7 hrs = 62 × 7
= 434 km.
Therefore, distance covered in 7 hrs = 434 km.
4. Mike drives his car at a speed of 70 km per hour. How much distance will he cover in 3 hours 30 minutes?
Solution:
Speed of the car = 70 km/hr
Time taken = 3 hours 30 minutes
= 3 ½ hours.
Distance covered in 1 hour = 70 km
Distance covered in 3 ½ hour = 70 × 3 ½ km
= 70 × 7/2 km
= 245 km.
5. How much distance will be covered in 1 ½ hour at a speed of 32 m per minute?
Solution:
[1 ½ hr = (60 + 30) minutes = 90 minutes].
Distance covered in 1 minute = 32 metres.
Distance covered in 90 minutes = 32 × 90 = 2880 m.
We know, 1 m = 1/1000 km.
= 2880/1000 km.
= 2.88 km.

Answer:
A) 75°
Step-by-step explanation:
It is the property of a polygon that the sum of the external angles is equal to 360°.
===============================================================
Solving :
⇒ p + 55 + 30 + 75 + 55 + 70 = 360
⇒ p + 85 + 130 + 70 = 360
⇒ p + 285 = 360
⇒ p = 360 - 285
⇒ ∠p = 75°
Answer :
A) 75°
because the property of polygon is equal to 360° the sum of external angles.

find the value of each variable
x=
y=
z=
Answer:
Step-by-step explanation:
A 45 degree angle in a right triangle produces 2 equal sides. In this case z and the perpendicular line are equal. So that's were we'll start. Then you move on to the 60 degree angle to get x and y.
Finding z
z^2 + z^2 = (24√2) Combine the left
2z^2 = 24^2 * 2 Divide both sides by 2
2z^2/2 = 24^2/2
z^2 = 24^2 Take the square root of both sides
√z^2 = √24^2
z = 24
Finding x and y
The perpendicular = 24. Because it is a 60 degree angle that's given, we can do this without a calculator.
Tan 60 = opposite over adjacent
sqrt(3) = Perpendicular / z Multiply both sides by z
z*sqrt(3) = perpendicular
The above calculation tells us the perpendicular is 24
z*sqrt(3) = 24 Divide by sqrt 3
z = 24/√3
z = 24/1.73
z = 8√3
Finding x
Use Pythagoras to determine x
Perpendicular^2 + (8√3)^2 = x^2
24^2 + 8^2*3 = x^2
576 + 192 = x^2
768 = x^2
√x^2 = √768
x = 27.71

There are 5 blue blocks, 7 red blocks, 2 yellow blocks, and 12 green blocks. What is the ratio of yellow blocks to total blocks?
Answer:
2:26.
Step-by-step explanation:
There are 26 blocks total, and compared to the yellow blocks, there are only two. So that would be 2:26.
Answer:
2:26
Step-by-step explanation:
A ratio is just a mathematical way to show a relationship between things. I wrote it with a colon (:), but you can write it as a fraction or words "x to b."
Most of the time in math, the order of how the question is asked doesn't matter. When it's a ratio, it does matter. Because they ask about the yellow blocks first, that has to be the first part of the ratio.
There are 2 yellow blocks.
Next, it asks for the total. That will be the other part. Add all the total blocks together: 5+7+2+12= 26.
There are 26 total blocks.
Technically, we can simplify this down to 1:13, but it's not asking to simplify it, so let's just leave it as 2:26.
