Mario tried to solve an equation step by step.

Zarrin [17]

Answer:

Step 2

Step-by-step explanation:

Mario made a mistake in Step 2 when substracting $\frac{1}{3}$ from $\frac{4}{3}$ . When substracting his result ended up being $\frac{2}{3}$ but it is actually....

$\frac{4}{3} - \frac{1}{3} = \frac{4-1}{3} = \frac{3}{3} = 1$

so the right answer is $q = 1$

Secant TP and tangent TR intersect at point T Chord SR and chord PO intersect

DochEvi [55]

Answer:

(C)x=11.6, y=23.2

Step-by-step explanation:

Using Theorem of Intersecting Secant and Tangent

$TQ$ X TP=TR^2$

$10(10+x+4)=16^2\\10(14+x)=256\\140+10x=256\\10x=256-140\\10x=116\\$Divide both sides by 10\\x=11.6$

Next, we apply Theorem of Intersecting Chords

PV X VQ=SV X VR

4 X x= 2 X y

Recall: x=11.6

2y=4 X 11.6

2y=46.4

y=46.4/2=23.2

Therefore: x=11.6, y=23.2

The correct option is C

X is -4 f(x)= 5x^8-3x The ^8 is the exponent for 5x!!!

hichkok12 [17]

Answer:

327692

Step-by-step explanation:

$65536 = (-4)^{8} \\ \\ 65536 \times 5 = 327680 \\ \\ 327680 - 3(-4) = 327680 + 12 = 327692$

According to the Order of Operations [GEMS(A)\BOMDAS\PEMDAS etc.], in this case, you evaluate the exponent BEFORE multiplying. This is a common mistake people make.

I am joyous to assist you anytime.

C²+5c-24=0 cant figure out how to solve this

frosja888 [35]

Just solve the quadratic, you need to figure out what value you can use to FOIL and get c^2+5c-24=0. so you need to figure out what values you can add together to get 5 and multiply together to get -24 so try (c+8)(c-3) here 8 and 3 make sense since 8-3 = 5 and 8*-3=-24 so the answer is (c+8)(c-3).
