Answer:

Option: B is the answer.

Step-by-step explanation:

As we know that an obtuse angle is an angle whose measure is greater than 90° but strictly less than 180°

Now the complement of such a angle could not exist because complement of an angle B is defined as:

A+B=90

A=90-B

now here B has measure >90° so on subtracting this quantity with 90° we will get a negative quantity and measure of any angle can't be negative.

<em>Hence, It is not possible for an obtuse angle to have both a complement and a supplement.</em>

We are asked about the incorrect statement.

Hence option B is the answer.

( B. It is possible for an obtuse angle to have both a complement and a supplement )

yarga [219]

Answer:

t = 21d

Step-by-step explanation:

Here tension and distance are denoted t by d and respectively. Since t varies directly with d , then the relation between t and d is k=td Given that, for the tension 42 pounds, the spring is stretched 2 inches. Substituting t = 42 and d= 2 into t = kd find the value of k . Therefore,

42= K (2)

$K=\frac{42}{2}$

K= 21

Thus the relationship is t = 21d

Tatiana [17]

Answer:

(9) $339076.60 (10) $72000 (11) $220800

Note: Kindly find an attached copy of the complete question given below. i solved for 9,10,11 only.

Step-by-step explanation:

Solution

Given that:

Betty set aside $200/month

With a 401 (k) savings

t = 40 years

APR = 5.4%

Now we find the balance in her account after 40 years.

Now,

A = PMT [(1 +r/n)^nt -1]/(r/n)

A = 200 [ (1 + 0.054/12)^(12)(40) - 1]/(0.054/12)

A= $339076.60

(10) Recall that:

t = 40 years

Per month deposit = $150 dollar

The total deposit becomes

t = 40 * 12 = 480 Month

Total deposit = 480 * 150

=$72000

(11) Now we find the less money she received in her paychecks

Thus

Without monthly saving paycheck is =$2300

Now,

For 40 years becomes = $2300 * 40 * 12

=$1,104000

So,

20% of tax deducted = 20/100 * $1,104000

=$220800

Therefore the less amount received in 40 years is $220800

Developing it says constructing equations from a table

12345 [234]

The equation is y=2x+1.
to find b in y=mx+b you simply look for a point where x=0 which was (0,1) making the y-intercept or "b" equal to 1. to find the "m" or slope plug in any point for x and y. (9)=m(4)+1 is 2=m. so y=2x+1 is your answer.
