Given:
The quadratic equation is :
[tex]16x^2-20x-6=0[/tex]
To find:
The quadratic formula for the given equation after substituting the values.
Solution:
If a quadratic equation is [tex]ax^2+bx+c=0[/tex], then the quadratic formula is:
[tex]x=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]
We have,
[tex]16x^2-20x-6=0[/tex]
In this equation, [tex]a=16,b=-20,c=-6[/tex].
Substituting [tex]a=16,b=-20,c=-6[/tex] in the above formula, we get
[tex]x=\dfrac{-(-20)\pm \sqrt{(-20)^2-4(16)(-6)}}{2(16)}[/tex]
Therefore, the required quadratic formula for the given equation after substituting the values is [tex]x=\dfrac{-(-20)\pm \sqrt{(-20)^2-4(16)(-6)}}{2(16)}[/tex].
In the figure, AB is tangent to circle C. Find the length of DB.
Answer:
8.5
Step-by-step explanation:
First we need to get BC using the pythagoras theorem
BC² = AC² + AB²
BC² = 8² + 15²
BC² = 64+225
BC² = 289
BC = √289
BC = 17
DB = 1/2BC
DB = 1/2 * 17
DB = 8.5
Hence the length of DB is 8.5

help me pls, question is on the picture
Answer:
I just learned this about a few weeks ago I hope this helps.
Step-by-step explanation:
Since it's cosine you're only looking at Adjacent and the hypotenuse which the adj is 20 and the hyp is 25 so since cosine is adj/hyp you do 20/25 then simplify it to 20/25 divide both by 5 so it's simplified to 4/5.
Then you do Cos-1(4/5)=36.869 which is rounded to the tenth 36.9 but rounded to the hundredth 36.87.
Hope this helps

Rahim was asked to make p the subject of this formula
Q = -7
He started his answer as follows
3Q = p - 21 hence p =
Complete Rahim's final answer.
Answer:
P =3Q +21
Step-by-step explanation:
Given: Rahim was asked to make p the subject of this formula
Q = p/3 - 7
He started his answer as follows
3Q = p - 21 hence p =
To Find, Complete Rahim's final answer.
Solution:
Q = p/3 - 7
Multiply both sides by 3
3Q = 3(p/3 - 7)
3Q = 3 × p/3 - 3 × 7
3Q = p - 21
Adding 21 both sides
3Q + 21 = p -21 +21
3Q + 21 = p
interchange sides
p = 3Q + 21
hence p =3Q +21

A rocket is launched from a tower. The height of the rocket, y in feet, is related to the time after launch, x in seconds, by the given equation. Using this equation, find the maximum height reached by the rocket, to the nearest tenth of a foot.
y=-16x^2+212x+139
Answer:
841.6 ft
Step-by-step explanation:
Solve this using the quadratic formula.
y=-16x^2+212x+139 becomes -16x^2 + 212x + 139. The x-value of the axis of symmetry is
-212
x = ----------- = 6.625 (This time measurement is in seconds.)
2(-16)
The maximum height reached by the rocket is the y value when x = 6.625 and is y(6.625) = 841.6 ft

A batch of 24 cupcakes requires 9 ounces of flower. Julio made 132 cupcakes for the bake sale. How many pounds and ounces of flower did he use?
Answer:
49.5 ounces the flower
3 pounds, 1.5 ounces
Step-by-step explanation:
Given that :
24 cupcakes 9 ounces of flower
Number of ounces of flower required for 132 cupcakes will be x
Using cross multiplication method :
24 cupcakes = 9 ounces
132 cupcakes = x ounces
Cross multiply :
24 * x = 132 * 9
24x = 1188
divide both sides by 24 to isolate x
x = 49.5
Hence, 49.5 ounces the flower is required for 132 cupcakes
To express in pounds :
1 pound = 16 ounces
49.5 ounces = 3 pounds 1.5 ounces

How many right angles are there in an angle that turns through 360º?
4 right angles
90 + 90 + 90 + 90 = 360
However, it that figure is a circle-- it may include 0 right angles since circles have no angles.
For every 1 circle there are

Find the measure of angel 3
Answer:
100
Step-by-step explanation:
Remark
If two opposite arcs are given by being opposite vertically opposite angles, then the value of both the vertically opposite angles are equal to
Vertically opposite angle = 1/2 (arc1 + arc2)
Givens
Arc1 = 60
Arc2 = 100
Solution
The red dot angle = 1/2 (60 + 100)
The red dot angle = 1/2(160)
The red dot angle = 80
Because the red dot angle and <3 are on the same line with the same common point, they are supplementary.
<3 and red dot = 180
<3 + 80 = 180 Subtract 80 from both sides
<3 = 180 - 80
<3 = 100
What is the measurement of R ?
Answer:
in a rhombus opposite angles are equal therefore it's also 135
A classmate buys and resells scooters. If they original buy a scooter for $45.85 and mark it up 90%. What is the new selling price?
Answer:
$87.12
Step-by-step explanation:
To mark up the price you are basically doing 45.85×190%.
If you take a percentage and make it a normal number you need to divide by 100.
190÷100= 1.9
So you multiply 45.85×1.9=87.115
Because this is money you cant have $87 and 11 and a half cents. So you need to round
You need to round up because it is 5, which means that you get $87.12
