Answer:

A) y ≥ -4

Step-by-step explanation:

The range of a function basically represents all of the y values that a function encompasses (I hope that makes sense, if not, please let me know).

In this graph, since the parabola has a vertex at (1, -4), the range includes y values only greater than or equal to -4. The function does not include y values lower than -4. Therefore, the range must be y ≥ -4.

Answer:

189

Step-by-step explanation:

If you mean this, my answer is 3x63= 189

${x}^{2} + {y}^{2} = 57 \\ xy = 3$

${x}^{2} + {y}^{2} + 2xy = 57 + 2 \times 3$

${(x + y)}^{2} = 63$

$3 {(x + y)}^{2} = 3 \times 63 = 189$

For each of the following integrals, indicate whether integration by substitution or integration by parts is more appropriate, o

Andrei [34K]

Answer:

a. ∫ xSinx dx

iii. integration by parts

u =x and dv= sinx

b. ∫ x⁴/(1+x³). dx

ii. neither

Long division is an option here before integration is done

c. ∫ x⁴. e^x³. dx

i. substitution

where u = x⁵

d. ∫x⁴ cos(x⁵). dx

i. substitution

where u = x⁵

e. ∫1/√9x+1 .dx

i. substitution

where u = 9x+1

PLEASE HELP ASAP!!! CORRECT ANSWER ONLY PLEASE!!!

Answer: $\bold{(A)\ a_n=7n-2}$

<u>Step-by-step explanation:</u>

The explicit rule for an arithmetic sequence is: $a_n=a_1+d(n-1)\quad \text{where}\ a_1\ \text{is the first term and d is the difference}$

In the sequence provided {5, 12, 19, ... }, the first term is 5 and the difference (d) is 12 - 5 = 7

$a_n=5+7(n-1)\\.\quad=5+7n-7\\.\quad=7n-2$
