sukhopar [10]

Answer:

(f-g) (3x)=27x^3+12+2

Step-by-step explanation:

First lets write the following:

(f-g) (3x)= f(3x)-g(3x)

Now we need to find equivalent expression for f(3x) and for g(3x), we will obtaine them by evaluating 3x instead of x in every 'x' appearance.

Wi have>

g(3x)= -27x^3+4

f(x)=12x-2

Now, lets perfomr the desired operation.

f(3x)-g(3x)=27x^3+12+2

5 Calculate 67% tax on $2.305.

quester [9]

Answer:

$3849.35

Step-by-step explanation:

2305/100 = y/167

2305 = 100% price

167% = +tax

167/100=1.67

do the same to the top.

2305*1.67=3849.35

the answer is $3849.35

Given:

The lengths PQ = 4x + 2, QR = 7x – 19, and QU = 34

We need to determine the value of ST.

Value of x:

By two tangent theorem, we have;

PQ = QR

Substituting the values, we get;

$4x+2=7x-19$

$-3x+2=-19$

$-3x=-21$

$x=7$

Thus, the value of x is 7.

Length of PQ and QR:

Substituting x = 7 in the expressions of PQ and QR, we get the lengths.

Length of PQ = $4(7)+2=28+2=30$

Length of QR = $7(7)-19=49-19=30$

Radius of the circle:

The radius of the circle PU can be determined using the Pythagorean theorem.

Thus, we have;

$QU^2=PQ^2+PU^2$

Substituting the values, we get;

$34^2=30^2+PU^2$

$1156=900+PU^2$

$256=PU^2$

$16=PU$

Thus, the radius of the circle is 16.

Length of ST:

The length of ST is $ST=SU+UT$

Substituting SU = UT = 16 because the radius of the circle is 16.

Thus, we have;

$ST=16+16$

$ST=32$

Thus, the length of ST is 32.
