Find the value of c so that the polynomial p(x) is divisible by (x-3). p(x) =-x^3+cx^2-4x+3. c=?

Answers

Answer 1

Answer:

[tex]\boxed{\textsf {The value of c is $\sf \dfrac{-14}{3}$. }}[/tex]

Step-by-step explanation:

A polynomial is given to us . We need to find the value of c so that it is divisible by (x-3 ) .The given polynomial to us is ,

[tex]\sf \implies p(x)=- x^3+cx^2-4x+3 [/tex]

And the factor is ,

[tex]\sf \implies g(x) = x + 3 [/tex]

Now , according to factor theorem , p(x) will be divisible by g(x) if p(-3) = 0

[tex]\sf \implies p(x)= - x^3+cx^2-4x+3 \\\\\implies\sf p(-3) = 0 \\\\\sf\implies -(-3)^3+c(-3)^2-4(-3)+3 = 0 \\\\\sf\implies 27 + 9c +12+3=0 \\\\\sf\implies 9c +42=0 \\\\\sf\implies 9c = (-42) \\\\\sf\implies c = \dfrac{-42}{9}\\\\\sf\implies \boxed{\pink{\sf c = \dfrac{-14}{3}}}[/tex]

Hence the value of c is (-14)/3 .
Answer 2

The value of c will be equal to -14/3.

What is an expression?

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that the expression is p(x) =-x³+cx²-4x+3. The value of c will be calculated as,

p(x) =-x³+cx²-4x+3

p(-3) =-(-3)³+c(-3)²-( 4 x -3) +3

p(-3) = 27 + 9c +12 + 3

27 + 9c +12 + 3 = 0

9c = -42

c = -42/9

c = -14/3

Therefore, the value of c will be equal to -14/3.

If 0 < f ≤ 90 and cos(22f − 1) = sin(7f + 4), what is the value of f?
f=3
f=4
f=5
f=6

Answers

Answer:

A

Step-by-step explanation:

We are given:

[tex]\cos(22f-1)=\sin(7f+4)[/tex]

Recall the co-function identity:

[tex]\sin(\theta)=\cos(90-\theta)[/tex]

Let θ = 7f + 4. So:

[tex]\sin(7f+4)=\cos(90-(7f+4))[/tex]

Substitute:

[tex]\cos(22f-1)=\cos(90-(7f+4))[/tex]

Remove the cosine:

[tex]\displaystyle 22f-1=90-(7f+4)[/tex]

Distribute:

[tex]22f-1=90-7f-4[/tex]

Subtract:

[tex]22f-1=-7f+86[/tex]

Add 7f and 1 to both sides:

[tex]29f=87[/tex]

Therefore:

[tex]f=3[/tex]

There are 195 adults and 320 children at a zoo. The zoo makes a total of $6,515 from the entrance fees, and the cost of an adult and a child to attend is $27, how much does it cost each for a parent and a child? Let a represent an adult. Let c represent a child. Enter a system of equations to represent the situation, then solve the system.

Answers

Answer:

a+c=27

195a+320c=6515

Step-by-step explanation:

adult (a): 195

children (c): 320

total $: $6515

child $: 27

a+c=27 --> c=-a+27

195a+320c=6515

sub the first equation into the 2nd equation to get a=17

sub a=17 into c=-a+27 to get c=10

so, an adult ticket is $17 and a child ticket is $10.

What is the equation for the nth term of the sequence
And what is the 52nd term of the sequence. -8,-12,-16

Answers

Given:

The sequence is -8, -12, -16.

To find:

The nth and 52th term  of the given sequence.

Solution:

We have,

-8, -12, -16

It is an AP because the difference between consecutive terms are equal. Here, first term is -8 and the common difference is

[tex]r=a_2-a_1[/tex]

[tex]r=-12-(-8)[/tex]

[tex]r=-12+8[/tex]

[tex]r=-4[/tex]

The nth term of an AP is

[tex]a_n=a+(n-1)d[/tex]

Where, a is first term and d is common difference.

Putting a=-8 and d=-4, we get

[tex]a_n=-8+(n-1)(-4)[/tex]

[tex]a_n=-8-4n+4[/tex]

[tex]a_n=-4-4n[/tex]

Putting n=52, we get

[tex]a_{52}=-4-4(52)[/tex]

[tex]a_{52}=-4-208[/tex]

[tex]a_{52}=-212[/tex]

Therefore, the equation for the nth term of the given sequence is [tex]a_n=-4-4n[/tex] and the 52nd term of the sequence is -212.

  33 ft²

Step-by-step explanation:

Each triangle's area is given by the formula ...

  A = (1/2)bh

  A = (1/2)(3 ft)(4 ft) = 6 ft²

The square base area is given by ...

  A = s²

  A = (3 ft)² = 9 ft²

__

The total area of the pyramid is the area of the base plus the area of four triangular faces.

  Total Area = (9 ft²) + 4(6 ft²) = (9 +24) ft²

  Total Area = 33 ft²

AABO=AOCD. Which of the following statements
is NOT true?”

Answers

Answer:

The statement that is not true is;

c) m∠ABO = m∠ODC

Step-by-step explanation:

With the assumption that the lengths AO, and OD are equal, we have that in ΔABO and ΔOCD, the following sides are corresponding sides;

Segment AO on ΔABO is a corresponding side to segment OD on ΔOCD

Vertices B and C on ΔABO and ΔOCD are corresponding vertices

Therefore;

Segments AB and OB on ΔABO are corresponding sides to segments OC and OD on ΔOCD respectively

Therefore, ∠ABO on ΔABO is the corresponding angle to ∠OCD on ΔOCD

Given that ΔABO ≅ ΔOCD, we have that ∠ABO ≅ ∠OCD

Therefore;

m∠ABO = m∠OCD by definition of congruency
