Critique the reasoning of others. Sally states that the equation g(x) = x2 + 3x − 10 represents a quadratic function that is the product of the expressions that define the two linear functions a(x) = x + 2 and b(x) = x − 5. Is Sally correct? Explain.
Answer:
Step-by-step explanation:
No, not quite. She's close.
The middle term (often called the linear term) is + which means that the absolute value of the factors must be plus.
(x + 5)(x - 3) is what should should think.
x + 5 = 0
x = - 5
x + 2 = 0
x = - 2
(x + 5)(x - 2)
x^2 - 2x + 5x - 10
x^2 + 3x - 10

Answer:
no
Step-by-step explanation:
Using the converse of Pythagoras' identity.
If the square of the longest side is equal to the sum of the squares of the other 2 sides then the triangle is right.
longest side = 30 , then 30² = 900
20² + 23² = 400 + 529 = 929 ≠ 900
Then the triangle is not right.

You throw a ball at a height of 5 feet above the ground. The height h (in feet)
of the ball after t seconds can be modeled by the equation h=-16tsqaured +44t +5
A. After how many seconds does the ball reach a height of 15 feet?
B. After how many seconds does the ball hit the ground? Round your answer
to two decimal places.
Answer:
A. After 2.5 sec and .25 sec the ball was at a height of 15 ft.
B. 2.86 sec is the time it takes to hit the ground
Step-by-step explanation:
A. let h = 15
then 15 = -16t^2 + 44t + 5
16t^2 - 44t + 10 =0
2(8t^2 - 22t + 5) = 0
2(2t - 5)(4t - 1) = 0
t = 5/2 = 2.5 or t = 1/4 = .25
After 2.5 sec and .25 sec the ball was at a height of 15 ft.
B. Let h = 0.
-16t^2 + 44t + 5 = 0
Use the quadratic formula to find t. (I will let you do that)
t = 2.85929... or t = -.10929...
t cannot be negative, so 2.86 sec is the time it takes to hit the ground
The answer of A is After 2.5 sec and 0.25 sec the ball was at a height of 15 ft and the answer of B is 2.86 sec is the time it takes to hit the ground.
A. let h = 15
What is the quadratic equation?
[tex]ax^2+bx+c=0[/tex]
a, b, c = known numbers, where a ≠ 0
x = the unknown
then 15 = -16t^2 + 44t + 5
16t^2 - 44t + 10 =0
2(8t^2 - 22t + 5) = 0
2(2t - 5)(4t - 1) = 0
t = 5/2 = 2.5 or t = 1/4 = 0.25
After 2.5 sec and 0.25 sec the ball was at a height of 15 ft.
B. Let h = 0.
-16t^2 + 44t + 5 = 0
Use the quadratic formula to find t.
t = 2.85929... or t = -.10929...
t cannot be negative, So 2.86 sec is the time it takes to hit the ground.

A helicopter flies from the airport on a course with a bearing of 21 degrees. After flying for 99 miles, the helicopter flies due east for some time. The helicopter flies back to the airport with a bearing of 227 degrees. How far did the helicopter fly on the final leg of its journey?
Answer:
Step-by-step explanation:
From the question we are told that:
Initial bearing [tex]\angle _1=21 \textdegree[/tex]
Initial distance [tex]d_1=99miles[/tex]
Final bearing [tex]\angle _2=227 \textdegree[/tex]
Let [tex]\triangle OAB[/tex] be the perimeter travailed
[tex]\angle OAB=90+21=111 \textdegree\\\angle ABO=270-227=43 \textdegree[/tex]
Generally the equation for OB using sine rule is mathematically given by
[tex]OB=99*\frac{sin111}{sin43}[/tex]
[tex]OB=135.52miles[/tex]

Please help asap
Answer:
9.7cm
Step-by-step explanation
According to the sine rule;
a/sinA = c/sinC
8/sin55 = c/sin82
Cross multiply
csin55 = 8sin82
c(0.8192) = 8(0.9903)
c = 8(0.9903)/0.8192
c = 7.9221/0.8192
c = 9.67
Hence the value of c to the nearest tenth is 9.7cm
I’m trying to bring my grade up by doing some makeup work so can someone please answer this for me please
Answer:
A and B (answer #2)
Step-by-step explanation:
right triangles: c^2 = a^2 + b^2
c is the largest side
for A: c = 5, a = 3, b = 4
5^2 = 3^2 + 4^2
25 = 25, so A is a right triangle
for B, c = 13, a = 5, b = 12
13^2 = 5^2 + 12^2
169 = 169, so B is a right triangle
for C, c = 4, a = 2, b = 3
4^2 = 2^2 + 3^2
16 ≠ 13, so C is not a right triangle
So, A and B are right triangles.

Ordena los términos del 1 al 5, de tal manera que
cada término se construya del término (s) anterio
Explica por qué cada figura está en el lugar que
eliges. Los términos son: cuadrilátero, cuadrado
rombo, rectángulo y paralelogramo
Answer:
El orden es;
1) Cuadrilátero, 2) Rombo, 3) Paralelogramo, 4) Rectángulo, 5) Cuadrado
Step-by-step explanation:
Los términos dados son;
Cuadrilátero; Una forma con cuatro lados
Rombo; Un cuadrilátero con cuatro lados iguales
Cuadrado; Un cuadrilátero con cuatro lados iguales y cuatro ángulos iguales y dos lados paralelos opuestos
Rectángulo; Un cuadrilátero con cuatro ángulos rectos y dos lados paralelos opuestos
Paralelogramo; Un cuadrilátero con un par de lados paralelos opuestos
Observamos que todos los términos son cuadriláteros, por lo tanto, el cuadrilátero es el primer término
Por lo tanto, tenemos,
La primera forma es el cuadrilátero,
El cuadrilátero se transforma en un rombo (un cuadrilátero con lados iguales)
El ángulo del rombo se ajusta para dar un paralelogramo
El ángulo de paralelogramo dado cuatro ángulos iguales de 90 ° para dar un rectángulo
El rectángulo se ajusta para dar un cuadrado con todos los lados iguales
solve 3(2x-5)-2x=3(X+7)
Answer:
x = 36
Step-by-step explanation:
Given
3(2x - 5) - 2x = 3(x + 7) ← distribute parenthesis on both sides
6x - 15 - 2x = 3x + 21
4x - 15 = 3x + 21 ( subtract 3x from both sides )
x - 15 = 21 ( add 15 to both sides )
x = 36
