Find the value of c so that (x+1) is a factor of the polymonial p(x)=5x^4+7x^3-2x^2-3x+c
Andru [333]

Answer:

BRAINLIEST PLZZZZ

Step-by-step explanation:

Also given that (x+1) is factor of given polynomial p(x).

Need to determine value of constant c.

We will be solving above problem using factor theorem.

Factor theorem says that if ( x – a) is a factor of any polynomial f(x) , then f(a) = 0.

As in our case f(x) = p(x) and factor of p(x) is (x + 1) , which can be rewritten as (x – ( -1)) , so "a" in our case is -1 .

According to factor theorem p(-1) = 0

On substituting x = -1 , in given expression of p(x) we get

Hence value of c in the given polynomial is 1

The first four numbers hexa said were 16 32 48 and 64 if she keep counting this way what is the 99th Number hexa will say
rewona [7]

Answer:

316,912,650,057,057,350,374,175,801,344

Step-by-step explanation:

You can see that this sequence is geometric so you need to know the geometric sequence which is x_{n} =r^{n-1} and if you plug in every thing you get x_{n}=2^{99-1} which would be 2^{98} which is 316,912,650,057,057,350,374,175,801,344

In a study of parents' perceptions of their children's size, researchers asked parents to estimate their youngest child's height
maks197457 [2]

Answer:

B) TS = -6.51, p-value = 0.0000

Step-by-step explanation:

Sample size, n = 39

μ = 7.5 cm

Null hypothesis, H₀ = 7.5 cm

(I.e. Average height of youngest child is 7.5 cm)

Alternative hypothesis, H_{a}\neq  7.5 (The youngest child's age is underestimated by 7.5 cm)

Standard deviation, \sigma = 7.2 cm

In order to be able to reject the null hypothesis,

the formula for the test statistic:

t = \frac{- \mu}{s/\sqrt{n} }

t = \frac{- 7.5}{7.2/\sqrt{39} }

t = -6.51

P - value

P(x < 7.5) = P(z < -6.51)

Checking the p-value for z < -6.51 in the normal distribution table

P(z < -6.51) = 0.0000

p - value = 0.0000
