Answer:

Interest = $63

Balance = $2,063

Step-by-step explanation:

Compound Interest Formula

[tex]\boxed{\sf I=P\left(1+\frac{r}{n}\right)^{nt} -P}[/tex]

where:

Given:

Substitute the given values into the formula and solve for I:

[tex]\implies \sf I=9000\left(1+\dfrac{0.014}{2}\right)^{2 \times 0.5}-9000[/tex]

[tex]\implies \sf I=9000\left(1+0.007\right)^{1}-9000[/tex]

[tex]\implies \sf I=9000\left(1.007\right)-9000[/tex]

[tex]\implies \sf I=9063-9000[/tex]

[tex]\implies \sf I=63[/tex]

Therefore, the account earns $63 interest in the first six months.

The balance after six months is $2,063.

Answer:

angle 1 = 51

angle 2 = 39

Step-by-step explanation:

The sum of two angles is equal to 90° since they are complementary angles

angle 1 + angle 2 = 90° rewrite equation using given values

x + 38 + 3x = 90 add like terms

4x + 38 = 90 subtract 38 from both sides

4x = 52 divide both sides by 4

x = 13 now to find the measure of each angle replace x with 13

angle 1 = 51

angle 2 = 39

and

[tex]m[/tex]∠[tex]CAB[/tex]=[tex]m[/tex]∠[tex]CAD[/tex]+[tex]m[/tex]∠[tex]BAD[/tex]

so

[tex]m[/tex]∠[tex]CAB[/tex][tex]= 29[/tex]°+[tex]29[/tex]°

[tex]m[/tex]∠[tex]CAB=58[/tex]°


Hope this helps!

Step-by-step explanation:

the graphic shows that the angle at A is split in half by the line AD (because the angles at both sides of the line are marked as equal, so the whole angle must be 2 times of one of these parts).

so, as CAD = 29°, CAB = 2×CAD = 2×29 = 58°

The solution set is 1 < x < 7.

According to the formula speed = distance / time The rate in miles per hour is 4.54

If you know how far something has traveled and how long it took to get there, you can calculate its average speed. Speed is calculated as follows: speed = distance * time. Knowing the units for distance and time is necessary to calculate the units for speed.

Rachel jogs 20 feet in 3 seconds

then by the formula

speed = distance/time

speed = 20 feet / 3 seconds

speed = 6.666667 feet per hour

but this speed is in feet per seconds to convert the speed from feet per seconds to miles per hour we need to multiply by 0.681818,

speed = 6.66667*0.681818

speed = 4.5454 miles per hour

Answer: -18 ==> C

Step-by-step explanation:

-9 + (-24) + 15 =

-9-24+15=

-(9+24)+15=

-33+15=

-(33-15)=-18 ==> C

Answer:

c) -18

Step-by-step explanation:

Given that,

→ x = -3

→ y = -6

Let's solve the problem,

→ 3x + 4y + 15

→ (3 × -3) + (4 × -6) + 15

→ -9 - 24 + 15 = -18

Thus, the solution is -18.

The polynomial of 3rd degree whose zeros and degree are given as for zero of (-2), multiplicity 1 and for zero of (3), multiplicity 2 is [tex]f(x)=(x^{3}-10x^{2} -15x+18)[/tex]

As per the question statement, a 3rd degree polynomial has a zero of (-2), multiplicity 1 and another zero of (3), multiplicity 2.

We are required to determine the polynomial.

Since, (-2) is a zero of the polynomial, then [tex][x-(-2)]=(x+2)[/tex] will be a factor of the polynomial. And since for zero of (-2), multiplicity is 1, this means that the factor of (x + 2) is only multiplied once.

Similarly, as (3) is another zero of the polynomial, then [tex](x-3)[/tex] will be a factor of the polynomial. And since for zero of (3), multiplicity is 2, this means that the factor of (x - 3) will be multiplied twice, i.e., [tex](x-3)^{2}[/tex].

Therefore, our function, say, f(x) will be [tex](x+2)(x-3)^2[/tex]

[tex]or, f(x) = (x+2)(x-3)^2\\or, f(x) = (x + 2)(x^{2} +9-12x)\\or,f(x) =x^{3}+9x-12x^{2} +2x^{2} +18-24x\\ or, f(x)=x^{3}+(2x^{2}-12x^{2})+(9x-24x)+18\\or, f(x)=(x^{3}-10x^{2} -15x+18)[/tex]

Hence, our required polynomial is [tex]f(x)=(x^{3}-10x^{2} -15x+18)[/tex]
