Answer:
The vertex of the graph is (-3,1)
Step-by-step explanation:
Here, we want to rewrite the given quadratic equation in the vertex form
We have the vertex form as;
y = a(x-h)^2 + k
where the vertex is (h,k)
Now, by completing the square, we have to divide the coefficient of x by 2, then square; after which we add to both sides; prior to this, we have to replace y by 0
Thus, we have it as follows;
x^2 + 6x + 10 = 0
x^2 + 6x + 10 + 3^2 = 3^2
x^2 + 6x + 19 = 9
x^2 + 6x + 9 = 9-10
(x + 3)^2 = -1
(x + 3)^2 + 1 = 0
So we have the vertex as ;
(h,k) = (-3,1)
can someone explain the answer ?
Answer:
x = 9.5
Step-by-step explanation:
Since you are given the adjacent side and need to find the hypotenuse then you need to use cos = adj/hyp so cos (47) = 6.5/x
So x = 6.5/.682, since cos 47 = .6819983601
x = 9.5
if a cricket makes 36 chirps in a minute, how many chirps can it make in 15 seconds?

write an equivalent expression for each of the following by combining like terms
3a+4(5a - 4)=
5b -2(5a -b) + 10a
Answer:
17a - 16
7b
Step-by-step explanation:
Given the following expressions
3a+4(5a - 4)=
Expand
3a + 4(5a)- 4(4)
= 3a + 20a - 16
= 17a - 16
For the expression
5b -2(5a -b) + 10a
Expand
5b - 2(5a)-2(-b) + 10a
5b - 10a + 2b + 10a
= 5b + 2b -10a + 10a
= 7b + 0
= 7b

3w - 10>-4
Answer:
If your trying to find w then it'll be 2
Step-by-step explanation:
3w - 10 > -4
+10 +10
3w > 6
3 3
w > 2
So I added 10 on both sides and guess positive 10 is bigger than -4, it'll be a positive 6. Then I divide 3 on both sides after I got 6 and thats how I got 2

<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3
Answer:
Let's solve your equation step-by-step.
11x − 2x + 15 = 8 + 7 + 9x
Step 1:
Simplify both sides of the equation.
11x − 2x + 15 = 8 + 7 + 9x
11x + −2x + 15 = 8 + 7 + 9x
( 11x + −2x ) + ( 15 ) = ( 9x ) + ( 8 + 7 )
( Combine Like Terms )
9x + 15 = 9x + 15
9x + 15 = 9x + 15
Step 2:
Subtract 9x from both sides.
9x + 15 − 9x = 9x + 15 − 9x
15 = 15
Step 3:
Subtract 15 from both sides.
15 − 15 = 15 − 15
0 = 0

What is the difference in area between a circle with a diameter of 3 meters and a square with a side length of 3 meters? Use 3.14 for pie.
pls help me
Answer:
The area of a circle with a diameter of 3 meters:
A = πr² = π(d/2)² = 3.14(3/2)² = 7.065 m²The area of a square with a side length of 3 meters:
A = a² = 3² = 9 m²The difference:
9 - 7.065 = 1.935 m²The square has greater area by 1.935 m²
Answer:
the difference in area between a circle with a diameter of 3 meters and a square with a side length of 3 meters=d²-π/4d²
=3²-3.14/4×3²=1.935m²
I need help with my hw
Answer:
x = 13, angle = 37
Step-by-step explanation:
The full angle will be a right angle, so 90 degrees.
You are given 53, on one side, so you just need to find the other bit.
Here, you can do 90 - 53 and get 37, which has to be equal to your unknown angle.
2x + 11 = 37
2x = 26
x = 13
Answer:
x=13
Step-by-step explanation:
we know that the 2 angles add up to a 90° right angle
53+ (2x+11) = 90
solving that, we're left with 2x= 26
26÷ 2= 13=x
hope this helps!

g(x) = 3x + 4; Find g(-4)
A) 10
B) -2
C) -17
D) -8
Answer:
-8
Step-by-step explanation:
so g(x) = 3x+4
to find g( -4) , it simply mean that to replace the x in the function g by the value given which is -4
so when u replaced it give you
g(-4) = 3(-4) +4
= -12 +4
= -8

One method that meteorologists could use to find the height of a layer of clouds about the ground is to shine a bright spotlight directly up onto the cloud layer and measure the angle of elevation from a known distance away. Find the height of the cloud layer in the diagram to the nearest tenth
Answer:
367.6 mStep-by-step explanation:
Use trigonometry
Let the height of the cloud be x, then we have:

Ayuda es un examen determinado raíz cuadrada entera de cada número y el residuo en cada caso º60 º86 º96 Raíz:_residuo:_ raíz:__residuo__ raíz__residuo
Answer:
Los pasos para calcular la raíz cuadrada entera y su residuo o resta se dará en la explicación;
Step-by-step explanation:
-60: Para saber exactamente cuál es su raíz cuadrada entera debemos buscar entre que cuadrados perfectos se encuentra comprendida este valor;
Tenemos que 7x7=49 y 8x8 = 64 (60 está comprendido entre 7 y 8) ,pero como la raíz de 49 se aproxima más a 60 entonces la raíz de 60 es 7 y su residuo o resta será el valor que falta para llegar a 60; así que tenemos:
[tex]\sqrt{60}[/tex]=7 ; residuo: 60-49 =11
-86: 9x9 =81 ;81 se aproxima más a 86 ,entonces la raíz cuadrada entera de 86 es 9 y su residuo es 5:
[tex]\sqrt{86}[/tex]=9; residuo : 86-81= 5
-96: 9x9=81 ; 81 por tanteo se aproxima más a 91,entonces la raíz cuadrada entera de 96 es 9 y su residuo es 15.
[tex]\sqrt{96[/tex]= 9x9 =81 ; residuo : 96-81= 15.
