The answer is letter c. If we talked about arithmetic sequence it has the explicit formula: A(n)= a+(n-1)d. So it showed in the choices that letter c has the correct formula for arithmetic sequence. It is the only formula if you are going to find nth term of an arithmetic sequence.

If Log x (1 / 8) = - 3 / 2, then x is equal to.<br><br> A. - 4<br> B. 4<br> C. 1 / 4<br> D: 0
Softa [21]

log_{x}(1/8)=-3/2

This is equal to...

x^{-3/2}=1/8

We want "x" so we need to isolate it using laws of exponents...

x^{(-1)(3/2)}=1/8

x^{3/2}=8 because x^{-a}=1/x^{a}

x=\sqrt[3]{8^{2}} because x^{a/b}=\sqrt[b]{x^{a}}

x = 4

answer: B

The expression 2.85+2.70M gives the taxi fare in dollars for a trip of M miles. On Thursday you got a find Miss Hearst took a ta
horrorfan [7]

<u><em>Answer:</em></u>

Total fair of the two trips was $32.7

<u><em>Explanation:</em></u>

<u>We are given that the expression that taxi fair is:</u>

2.85 + 2.7M where M represents the number of miles

<u>1- For Thursday:</u>

Number of miles covered = M = 6 miles

<u>Substitute with M=6 in the given equation to get the fair on Thursday as follows:</u>

Fair on Thursday = 2.85 + 2.7(6) = $19.05

<u>2- For Friday:</u>

Number of miles covered = M = 4 miles

<u>Substitute with M=4 in the given equation to get the fair on Friday as follows:</u>

Fair on Friday = 2.85 + 2.7(4) = $13.65

<u>3- The total fair:</u>

Total fair = fair on Thursday + fair on Friday

Total fair = 19.05 + 13.65 = $32.7

Hope this helps :)

Find the HCF of 960 and 432​
sdas [7]

Answer:

48

Step-by-step explanation:

Using Uclid's division algorithm, the HCF of 960 and 432 can be obtained as follows:

Here, 960 is greater and 432 is smaller. We divide 960 by 432.

STEP 1:

960 = 432*2 + 96

STEP 2:

Divide divisor (432) by remainder (96)

432 = 96 * 4 + 48

STEP 3:

Divide divisor (96) by remainder (48)

96 = 48 * 2 + 0

Since, remainder at this step is zero (0), so the HCF would be the divisor of this step which is 48.

Thus, HCF of 960 and 432 is 48

You are visiting a Redwood tree forest and want to verify the height of one of the trees. You measure its shadow along the groun
padilas [110]

Answer:

(a)55^o

(b)350.1ft

Step-by-step explanation:

The sum of the angles inside a triangle must be 180°, but from the right angle we already have 90°, so the sum of the two acute angles is 90°, then:

90^o-35^o=55^o

Let s be the length of the shadow and h the height of the three, so tan(35) is

tan(35^o)=\frac{h}{s}

Solving that last equation for h:

h=s*tan(35)=500(0.7002)=350.1ft
